CHAPTER - II

RESEARCH & DEVELOPMENT

CPRI has been taking up R&D programs in various areas of electrical power generation, transmission and

distribution in its endeavor to assist utilities to supply reliable and quality power to the consumers. The broad

objectives with which the research projects are taken up in CPRI are:

1. Offering technical advise and trouble shooting

2. Product development and improvement to meet global standards

3. Bridging gap in testing and develop special testing technologies

4. Large collaborative research projects with utilities and industries.

5. Electrical products and process Improvement

While some are undertaken in collaboration with industries & utilities, while others are taken up in-house to

develop the expertise and infrastructure to serve the power sector. The project proposals are planned well in

advance keeping in mind the needs of the industry / utilities and are cleared by the Committee on Research.

The project monitoring committee was constituted for the purpose of periodical review of the progress and to

suggest measures for timely completion of the projects as per the project implementation plan.

During the year under report 23 projects with total outlay of Rs. 624.81 lakhs were investigated. Among the

projects investigated 8 projects have been completed during the year. Six new projects at a total outlay of Rs. 204

lakhs have been taken up during the year.

Some of the completed projects have resulted in development of products and processes and the end results are

directly available for commercialization, thus benefiting the power industry. List of developments are given

below:

Investigation on application of FACTS devices in Indian Power systemsObjective of the project:

(a) To investigate the control interactions of various Flexible Alternating Current Transmission System

(FACTS) devices.

(b) To explore the optimal location of selected FACTS devices in Indian system

Power system Engineers are currently facing challenges to increase the power transfer capability of the

transmission line. The proven technologies are High Voltage Direct Current (HVDC) transmission & FACTS

devices and the latter one offers an economical solution for maintaining steady state & transient stability margins.

With the recent addition of FACTS devices to Indian power system it is necessary to investigate the control

interactions of FACTS devices in the same electrical area. The frequency ranges of the different control

interactions have been classified as steady state interactions (0Hz), Electromechanical Oscillations (0-3/5Hz),

Control or small signal Oscillations (2-15Hz), Sub-Synchronous Resonance (SSR) Interactions (10-50Hz) &

High frequency interactions (>15 Hz).


12

12

NREB system in India was chosen to investigate the control interactions of various FACTS devices as it comprises

of Static VAr Compensator (SVC) at Kanpur, Thyristor controlled series compensation (TCSC) on Kanpur –

Ballabgarh line and Rihand- Dadri HVDC line. Load flow analysis was carried out in SIMPOW software for the

reduced North region electricity board system and base case was finalized so that they are no steady state

interactions. Eigen value analysis was carried out and different modes of oscillations were found for this multi

machine system. Among the different electro mechanical modes it is found that one mode of 0.8Hz was most

critical. As the standard controller for TCSC is not available, controller was designed in SIMPOW using Dynamic

Simulation Language through small signal analysis. Various signals were considered for design of damping

controller as the choice of input signal was very critical to effectiveness of TCSC and Voltage across transmission

path was found to be most suitable control signal for damping the power oscillations.

Control or small signal Oscillations are investigated by plotting the impedance plots in frequency scanning

method and it is found that there is no parallel resonance. High frequency interactions were studied by considering

the 3 phase to ground faults at different buses & found that the critical inter-area mode was excited and oscillations

were damped out by TCSC damping controller. It was also found through simulation that, SVC located at

KANPUR was not effective in damping power oscillations compared to TCSC damping controller. It was also

observed that HVDC is very good in damping inter-area oscillations but excites local modes.

As critical modes identified and damped with the design of TCSC controller are not excited with the presence

of TCSC & HVDC controls in Northern Region Electricity Board (NREB) system it is concluded that there are

no control interactions in NREB system.

Achieved results:

Developed expertise to investigate application and interaction of multiple FACTS devices in Indian Power

systems.

Benefits:

Studying the controller interactions of multiple FACTS devices is a crucial in the Indian Power Systems with

multiple FACTS devices being added.

Studying the controller interactions of multiple FACTS devices is a subject of research world wide and proposed

study will contribute to the existing knowledge in this field.

This Study enhances the Research and Development strengths of the division and enables us to take up the

additional consultancy services in this area.

Doubly fed induction generators connected to the utility AC grid for disturbances such as

(a) Change in wind speed

(b) Faults within the wind farm

(c) Voltage dips in the utility grid

(d) Variation in frequency in the utility grid

3. Performance of Diesel Generator integrated with wind generator

The above aspects have been studied and compared through simulation studies using MATLAB software.

Achieved results:

1. This project has helped in increasing the knowledge on the transient/ dynamic behavior of wind farm

systems and their interaction with the rest of the power system under various system contingencies.

2. The study results indicate that integrating of wind farms to the grid necessitates planning/feasibility

studies to be performed.

Benefits:

Consultancy services in this area can also be taken up by the division.

Nano composites for flame retardant applications – Exploratory StudyObjective of the project

To prepare Nanofillers in the laboratory by chemical method.

To develop composites using nanofillers for Fire Retardant Low Smoke Cable application (FRLS).

Achievements:

Combustion method was used for development of nano filler, based on alumina. The characterization of laboratory

prepared nano filler was done using Thermo-Gravemetric Analysis (TGA), Differential Scanning calorimeter

(DSC), Scanning Electron Microscope (SEM), Particle Analysis, X-ray Fluorescence Spectrometer (XRF) and

X-ray Diffracto meter (XRD) . Using Sherr’s equation the particle size of the filler was calculated and was found

to be in the range of 42 nm.

Alumina filler developed was used in Polyvinyl Chloride (PVC) formulations and comparative evaluations were

carried out in respect of mechanical, electrical and Flame retardant and low smoke properties. The new formulation

was comparable in electrical properties with composites made using commercial nanoclay.


14

14

Benefits

Laboratory prepared alumina-nano filler showed superior characteristics as compared to the commercially

available nano clay.

Results indicate the superior PVC composites using the lab prepared nano filler.

Tensile strength and % Elongation were improved to a considerable extent.

Studies on thermoplastic elastomers for halogen free, fire retardant low smoke cablecompounds

Objectives of the project

To develop halofen based Low smoke Flame Retardant Wire & Cable Compounds by using Ethylene

Propylene Di-monomer (EPDM), Ethylene Vinyl Acetate (EVA), Nitrile Rubber and other thermoplastic

elastomers.

Achievements

EPDM based formulations were evaluated for oxygen index, smoke

density, halogen acid and Ultra violet (UV) stability studies. The

formulations showed excellent properties for fire retardant applications.

Trial extrusions were carried out at CIPET Mysore. During extrusion

temperature rise was observed in middle zones of extruder and

indicated the need for additional cooling in these zones for EPDM

based systems.

Benefits:

The developed compositions were satisfactory.

The base formulation developed using EPDM has been filed in the form of a patent.

Insulation diagnosis by high voltage spectroscopyObjective of the project

To characterize the extent of deterioration of dielectrics in

frequency domain with application to Power transformer

and Power Cable Systems, employing HV Dielectric

Spectroscopy.

Adaptation of this technique as a diagnostic tool for

assessing the condition of insulation in Power transformers

and MV Power cable systems in-service.

The results of the investigation to be used to formulate

guidelines on remedial measures.


15

The condition assessment of power station equipment is fast emerging as a diagnostic tool for the maintenance

of the equipment. Most of the utilities are aware of the importance of the condition based monitoring of the

equipment. Transformers and Power cable systems play a vital role in the Power system network.

During the project, detailed investigations were carried out by measuring dielectric parameters in frequency

domain on transformers of various ratings and also on MV Power Cable systems, to evaluate the extent of

deterioration and also to categorize the type of degradation using state of art equipment, HV Dielectric

Spectroscopy. By adapting this technique, an effective diagnostic tool for assessing the condition of insulation in

Power transformers and MV Power cable systems in-service, could be established.

Experiments were carried out in the laboratory on model transformers and on representative power cable samples

of Paper Insulated Lead-Covered (PILC), Cross Linked Poly Ethylene (XLPE) & mixed power cable systems, by

subjecting them to accelerated electrical stress. At various interval of ageing, dielectric parameters like Dielectric

loss, Power Factor, Capacitance & Permittivity in frequency domain were monitored.

Transformers of various ratings and on MV Power Cable systems to assess their healthiness.

Achievements:

After analyzing the data obtained on transformer insulation, both at site and in the laboratory, it was possible to

distinguish the degradation due to each dielectric medium (oil or paper) from a single spectrum. Moisture

content in cellulosic insulation and conductivity of the oil could be estimated. It was also observed that

measurements of dielectric parameters in frequency domain yielded more information on the insulation

system,compared to those monitored at power frequency.

A pilot project was undertaken with one of the utilities to assess the condition of the Power cables in their

distribution network. During this project, a large number of MV Power cable systems with different types of

joints & terminations were monitored for their healthiness. From the analysis of the voluminous data obtained

from the laboratory studies as well as from field measurements, it was possible to estimate the moisture content

in PILC cables and identify the influence of accessories on the cable system. The study also helped to identify

the deterioration of XLPE Power cables due to presence of water trees. The power cables could be ranked based

on the extent of deterioration of the cable insulation system.

Benefits:

The analysis of the large data bank created during the investigation, by conducting measurements in the

laboratory and also on in-service Transformers & Power cable systems, has helped in suggesting guidelines on

remedial measures to be taken for maintenance & replacement strategy based on the extent of degradation of

the dielectric medium.

From this it could be established that the technique using Dielectric Spectroscopy is a sensitive diagnostic tool

to assess the healthiness of in-service Power Transformers & MV Power Cable Systems.

Establishment of research facility for communication protocol applicable to sub stationautomation

Objective of the project

Electric power transmission utilities were among the first industrial

entities to embrace data telemetry and telecontrol on a wide scale.

Remote monitoring and control systems were first implemented

in the early 60’s and have progressively grown and evolved since

then. Early SCADA systems provided very rudimentary monitoring,

logging of digital chances and periodic sampling of analog data.

System integrators were confronted with a difficult challenge

whenever equipment from different vendors was integrated into a

single system. The different control protocols, parameters and operational philosophies often meant that it was

difficult and some times impossible to make the disparate components operate sensibly in a similar combinations

of equipment, their differing operational regimes and priorities sometimes prevented useful cost cutting through

sharing of design or integration information.

In the light of these difficulties, system integrators perceived the need for standardization of interfaces between

control equipment so as to reduce the cost and complexity of control system integration and testing.

Achievements:

CPRI has set up a comprehensive utility Competency Centre to address Product certification to various

protocols like IEC 61850, 60870 etc, Training utility personnel and offering consultancy services.

CPRI represents Indian Utilities’ interest at International forums regarding substation automation protocol.

Became Member in international organization like Modbus, DNP, OPC Foundation and UCA

Benefits:

CPRI conducted one International Workshop for over 350 persons.

The project has created new markets for protocol testing for utilities and manufacturers

Estimation and analysis of radiated electromagnetic emission of switchgears, powerequipment with augmented test facility for EMI measurement

Objective of the project

Development of test facilities for testing of Energy Meter for radiated electromagnetic emission test as per

the new IEC standards

17

Obtaining data on electromagnetic radiation generated by switchgears & power equipment and analysis &

estimation of electromagnetic radiation in the vicinity of these equipments

Achievements:

Test facility for radiated electromagnetic emission in Open Area Test Site as per standard CISPR – 22 has been

developed. Experiments were carried out to obtain electromagnetic radiated emission data of various equipments

– like Motor, Industrial Drilling Machine, Moulded case circuit breaker (MCCB) , Welding Machine, Air circuit

breaker (ACB) etc.

The experiments were carried out in open area test site using the test facilities developed. The experiments

were also carried out using other methods to find out the emission from power line of the equipment. With this

it was found that the noise in most of the case of power equipment was not from the equipment itself but it was

more carried in the power line cable of the equipment. The experiments were carried out in the range of 30 MHz

to 1.0 GHz.

Benefits:

The test facility for testing of Energy Meters as per IEC 62052-11 has been developed. The old standard for

Energy meters IEC 60687 and IEC 61036 have been changed to IEC 62052-11, IEC 62053-21 and IEC 62053-22,

wherein the testing method has been changed. Therefore by developing the open area test site for radiated

emission testing we are able to comply with the new standards and also we could retain the above test in the

NABL scope of accreditation.

Data on radiated emission of various power equipments and switchgear has been obtained which gives the level

of radiation of radiated electromagnetic emission of these equipments. The data can be provided to BIS and

IEC, which could be used for deciding appropriate tests methods for these equipments.

MoP provides funds under RSOP for Applied Research / Technology development to Academic Institutions /

R&D organizations / Institutes / Utilities etc. This Research fund is managed by CPRI since the year 2001.

NATIONAL PERSPECTIVE PLAN

The Indian Power Sector is facing major challenges today with the introduction of reforms, globalization and

liberalization policy of the government. Despite our country’s the power system planners have given utmost

importance to energy sector since beginning and there being manifold increase in installed generation capacity

and transmission networks. With increase in system expansion stability and security problems have become

challenging. It is of vital importance to focus our attention now on ways and means to build expertise within the

country, to find solutions for the problems existing in the system and also for the problems that may arise in the

future. Research is urgently needed to bridge the knowledge and technology gaps, more so due to changes in

technology today at a more profound and faster pace in the new millennium.

Realizing the importance of Research & Development, The Ministry of Power constituted a Standing Committee

on R&D to frame 15 years national Perspective Plan for R&D in Indian Power Sector under the chairmanship of

Chairman, Central Electricty Authority and CPRI as member convenor. While formulating the National Perspective

Plan, it is important to critically review the growth of power sector, assess the existing R&D infrastructure in the

BRIEF NOTE ON THE NEW PATENT APPLIED

1. A DEVICE FOR CARRYING AND MANIPULATING ULTRASONIC PROBE FORINSPECTION INSIDE A SHAFT/ROTOR BORE

Inspection inside bore of a rotor is often required to assess integrity of shaft or rotor. Since approach is notgenerally available for manipulating the transducer or probe with hand, a mechanism/device is used forcarrying out required movement and other manipulations. Several devices are in use but are disadvantageous.In view of this, a new design was attempted to alleviate some disadvantages of the systems. The result is acompact device, which can perform the task. The basic kinematic arrangement is as described below.

The actuator which carried the inspection head assembly, is supported on two sets of rollers in two differenttransverse planes at ends in such a way that the actuator can slide over the rollers in axial direction. Theactuator support roller assemblies are mounted in radial directions on the flanges of a rotary carrier. Therotary carrier is supported by two roller assemblies. The carrier can rotate in circumferential direction. Thisarrangement allows the actuator to move along the axial and circumferential directions simultaneously andindependently. The carrier support roller assemblies are supported on a frame. While rotating, the entirecarrier unit is prevented to shift in axial direction by means of axial guide rollers resting on a collar extendingfrom carrier.

2. NITROGEN HETEROCYCLE AS AN ACCELERATOR FOR CURING OF EPOXY RESINSYSTEM

With an objective of developing suitable accelerator/curing agent based on nitrogen heterocycles for curingof epoxy resins used for electrical applications, the investigation on nitrogen heterocycles on cure propertiesof epoxy resins has been carried out. Epoxy resins are currently among the most intensively investigatedcompounds as electrical insulators owing to their remarkable chemical resistance, good adhesion,extraordinary toughness high mechanical strength and good heat resistance. The applications of epoxyresin depend on the nature of curing. Generally curing takes place in the presence of a hardener or a curingagent. Chemical reactions that take place during the period of curing determine the properties of the curedthermoset material. A large number of nitrogen heterocycles based on several metals and ligands have beenstudied with regards to their cure behaviour with epoxy resins used for electrical applications.


22

22

The data suggests that the presence of 2-3 bis (benzimidazolyl) pyridine is effective in curing process of theepoxy resin system with appreciable reduction in the cure time of the resin system. At 1400C, it is observedthat at a concentration of 0.0625 phr of the ligand the cure time decreases from 293 minutes to 40 minutes.The reduction of cure time of epoxy resin systems in an industry at the time of manufacturing variousinsulating components is of commercial importance. It is suggested that the manufacturing industries canmake use of the newly developed accelerators, which can efficiently work in place of conventional type ofaccelerators. The effect of this ligand on the electrical properties has been studied and found that at lowerconcentrations no deterioration of the loss factor values was observed even at elevated temperatures.

3. A SYSTEM FOR MEASURING THERMAL ENERGY GAINED BY A WATER STORAGETANK

The main objective of the invention is to measure the thermal energy gained by each isothermal layer ofstorage water heating system and integrating to compute the total energy absorbed in the tank. Anotherobjective is to precisely track the energy inputs and energy outputs to the solar water heaters therebyauditing the energy flows through the system and detecting performance deterioration in thermal systems.The thermal efficiency of the system is computed using the data on solar radiation input and the energyoutput. The metering of thermal energy enables the estimation of the output energy developed by theprocess. Based on measurement of incident solar radiation and its integration and the energy output of thecollector, the thermal efficiency of the collector can be computed for a heating period.

The advantages of this meter over other meters are:

a) Static in nature with no moving parts

b) Accuracy upto 10%

c) Maintenance free

d) No costly replacements needed

Accelerated Power Development & Reforms Programme (APDRP)

Central Power Research Institute (CPRI) has been functioning as Advisor-Cum-Consultant (AcC) for the purpose

of capacity building in the State Electricity Boards (SEBs) / Power Utilities of Karnataka, Kerala and Andhra

Pradesh under the ACCELERATED POWER DEVELOPMENT AND REFORMS PROGRAMME (APDRP) of

Government of India since 2001. This prestigious consultancy appointment has been made by the Ministry of

Power, Government of India considering CPRI’s expertise in the areas of Power Transmission and distribution

studies and also similar consultancy services rendered by CPRI to Electricity Regulatory Commissions in India.

Initially, activities were confined to three distribution Circles in each of the above states in which the up gradation

of Sub-transmission and Distribution System were being carried out under the APDRP.


30

30

Since May 2005, the activities of CPRI as AcC have been extended to the entire states of Andhra Pradesh,

Karnataka and Kerala in addition to the three circles per state assigned earlier since majority of towns in these

states were also included in the APDRP Scheme for up gradation.

Benefits due to implementation of APDRP:

Andhra Pradesh: Eastern Power Distribution Co. Ltd (EPDCL) of Andhra Pradesh has achieved AT&C loss of

less than 10% for the entire utility, which is an important landmark achieved for the first time by any utility in the

country.

Karnataka: Zero percent Distribution Transformer failure rate has been achieved in Bangalore Metropolitan

Area of BESCOM. Bangalore is the only city in India to achieve this milestone.

Kerala: The Distribution failure rate in the entire Kerala is less than 4.5%, which is a major achievement.

Due to the focused programme of Energy audits by CPRI in major towns of Andhra Pradesh, Karnataka &

Kerala, the need for AT&C loss reduction has gained momentum in these states.

Average Revenue Realization has increased, the power supply quality has improved, the rate of Distribution

Transformer failure is reduced, and Average Technical and Commercial Losses have consistently reduced

in all the three states.

CPRI has played an important role as AcC in assisting the utilities by monitoring continuously the implementation

of the Distribution reforms, contributing to better practices in Distribution system, Quality assurance etc.

8. AUGMENTATION & MODERNIZATION OF CPRI LABORATORIES

The Testing, Research & Consultancy activities require the laboratories to be accredited and all equipmentcalibrated to carryout testing as per National/ International standards. Since most of the test equipment isoutdated, operation & maintenance of these equipment calls for very high expenditure. Many of the originalmanufacturers/suppliers of the equipment either did not exist or the companies have got merged with othercompanies, it is generally observed that spares and services are not available form the equipment suppliers,hence it is proposed to Augment & modernize some of the CPRI laboratories at a cost of Rs. 2329.5 lakhs.Several laboratories like, The High Voltage, Short Circuit, High Power Lab. Material Technology have beenaugmented and also the Rejuvenation of physical infrastructure is being carried under the scheme.

9. RELOCATION OF REGIONAL TESTING LABORATORY, MURADNAGAR, U.P. TO NOIDA

At present only CPRI has the necessary comprehensive capital intensive testing facilities under one roof fortesting & certification of electrical equipment. There has been persistent demand from manufacturers ofpower apparatus to establish Regional Testing Laboratories to cater to the testing needs of industriessituated in the respective regions of the country. Clients are facing lot of difficulties at present in sendingthe equipment from one end to the other for certification needs. The other important aspect has been thatlack of such adequate testing facilities in the regions to meet the demand which naturally force the useragencies to use untested equipment which may, not only introduce hazards to working personnel, but alsomake the system unreliable with frequent failures. Considering the above aspect and also realising theimportance of the demand of power industry for proper testing facility in the regions, there was a need andurgency for providing such regional test facilities for the benefit of manufacturers of power equipment.To cater to the northern Indian utilities, the Regional Testing Laboratory was started in 1992 at Muradnagar(near Ghaziabad) of UP. The inaccessibility of the testing Lab and worsening power situation has forced toshift the test lab to NOIDA. The project sanctioned at a cost of Rs.869 lakhs is under implementation. TheNOIDA authorities have allotted land near Ghaziabad and the civil works are likely to commence soon.
