3.1 There were no major Grid Disturbances in the Southern Regional Grid

during the year 2006 – 2007. However, the system occurrences and minor trippings

that took place in the constituent systems were discussed in detail, regularly in the

Protection Sub-Committee meetings and necessary rectification / remedial

measures suggested by the Protection committee were taken up for implementation

by the constituents to avoid its recurrence.

3.2 The Protection Sub-Committee of SRPC analyses the Grid Disturbances,

System Occurrences and other trippings that occur in the Southern Regional Grid

and suggests measures to avoid their recurrence. The functions of the Protection

Sub-Committee in brief are as follows:

a) Analysis of the Grid Disturbances, System Occurrences and other trippings and

to suggest measures to avoid their recurrence.

b) Coordination of settings of protective relays in the Regional System to maintain

the security of the Grid.

c) Periodical review of under frequency load shedding schemes, df/dt load

shedding schemes and other protection schemes adopted in the Grid.

d) Review of the implementation of recommendations made by the inquiry

committee of the grid disturbances in the region concerning to above matters.

e) To suggest, discuss and implement special protection schemes to take care of

major loss of import / generation so as to ensure security of the Grid.

29

During the year 2006 – 2007, the Protection Sub Committee met twice (1st

and 2nd

Protection Sub Committee meeting on was held on 25.07.2006 and

08.12.2006 respectively). The 2nd

Protection Sub Committee meeting was

preceded, by the meeting of the Working group on Protection.

3.3 The following issues were deliberated/ implemented by the constituents in

the Protection Committee of SREB/Protection Sub-Committee of SRPC during the

year:

a) The load relief obtained at different settings of flat under frequency

relays provided in the constituent systems was reviewed for their

correctness during system occurrences / disturbances and

necessary remedial measures recommended by the committee

were implemented by the constituents.

b) The operation of df/dt relays in the constituent systems was

reviewed periodically. The operation of this scheme and the

quantum of load relief obtained is also being monitored regularly for

its effectiveness.

c) Carrier Protection in the Kaiga corridor (Nagjhari-Kodasalli on

17/08/2006, Kadra-Kodasalli on 18.08.2006, Kaiga-Kadra & Kaiga-

Kodasalli on 19.08.2006) has been installed by KPTCL.

d) Bus Bar protection at Somanahalli 220 kV substation has been

commissioned by KPTCL on 08.09.2006.

e) Kaiga have implemented an inter trip scheme at Kaiga generating

station to avoid over loading & tripping of Kaiga – Guttur lines

whenever the power flow gets diverted towards Kaiga due loss

evacuation lines between Nagjhari and Hubli stations. With the

above scheme 220kV Kaiga – Kadra & Kaiga – Kodasalli lines

would trip, whenever the current reaches 750 amp /1.5 sec on

Kaiga-Guttur 220 kV line. The tripping is interlocked with the

availability of one of the 400 kV Kaiga-Narendra lines.

30

f) Islanding scheme for Kaiga generating station is under discussion

in the protection sub committee. The scheme considers islanding of

Kaiga Units I&II along with 250 MW of KPTCL load.

g) Islanding scheme for NTPC, Ramagundam STPS is under

discussion in the protection Sub-Committee. The scheme considers

islanding formation with one unit of 500 MW and one unit of 200

MW of Ramagundam along with radial loads of Andhra Pradesh

connected to ICTs at RSTPS to avoid total shutdown of RSTPS

during grid disturbances. Subsequently APTRANSCO proposed to

form an Island for Hyderbad with Ramagundam generators. Now

the discussions are on for designing an islanding scheme of

Ramagundam generators with local loads as well as Hyderabad

loads of APTRANSCO.

h) Islanding scheme for NTPC, Talcher STPS is also under discussion

in the protection sub committee. The scheme considers the

disconnection of Talcher Stage –II Units from ER grid during under

frequency conditions and forming island with Southern Region

through Talcher-Kolar HVDC link.

i) Special Protection Scheme (SPS) for 2X1000 MW Kudankulam

Nuclear Power Plant (KNPP) is under discussion in the protection

committee. 1000 MW generators at KNPP is biggest size generator

in Southern Region whose outage could pose frequency instability.

SPS for KNPP is being worked out to care of contingency of loss of

generation due to tripping of one/ two units. A special working

group was formed in the 1st Protection Sub Committee meeting and

was entrusted with task of designing the logic scheme of the SPS

with various micro level engineering options. The special working

group submitted its report for approval by Protection Sub

Committee in its 2nd

meeting held on 08.12.2006. The sub

committee agreed to the recommendations of the special working

group except for implementing agency at Kudankulam, so the issue

was put up to TCC/SRPC for their consideration. The matter is still

under consideration of TCC/SRPC.

31

j) Up gradation to 400 KV operation of Kaiga-Guttur DC link was

under taken. The Kaiga-Guttur circuit-II has been put into regular

operation from 14.07.2006 after changing all the defective

insulators. Similarly circuit-I was charged 400 KV level w.e.f.

07.03.2007 after changing all the defective insulators.

k) KPCL have implemented a selective tripping scheme at Nagjhari

generating station to save the simultaneous tripping of all units at

Nagjhari in the event of Nagjhari having been cut-off from load

centre Hubli on account of fault & operation of reverse power

protection taking place at Kaiga, tripping Kaiga – Kadra / Kodasalli

lines and thus leaving Nagjhari generators without any evacuation.

A revision in settings on the above scheme suggested by the

protection Sub Committee was implemented by KPCL on

10.08.2006.

l) A review meeting was held at CEA, New Delhi, on 22-12-2006 to

discuss the revised tripping scheme for Talcher STPS II units

during outage of Talcher – Kolar link, proposed by NTPC. The

implemented scheme was based on 450 MW jerk to the ER system

whereas the revised scheme is based on the presumption that the

ER-NR-WR grid bear a jerk of 1100 MW after commissioning of

Tala Transmission system. The meeting was taken by Member

(PS), CEA wherein it was agreed that:

o Revised scheme to be designed to in such a way that the

sudden impact on NER-ER-WR-NR system is less than

1000 MW

o Scheme should cause minimal trippings of Talcher II units.

The unit tripping alongwith run back of other unit(s) could

be implemented in such a way that the total relief comes in

about 4-5 seconds

o NTPC may look into the possibility of designing the scheme

by measuring inrush into ER grid and building the scheme

logic accordingly.

32

m) In view of the system occurrence in Karnataka on 01.11.2006 at

14.08 hrs, wherein one Kaiga Unit got poisoned out, a special

working group was formed in the 2nd

Protection Sub Committee

meeting held on 08.12.2006 for reviewing the relay settings in

Kaiga related corridor. The special working group held a meeting at

Kaiga on 8th and 9

th Feb 2007 and has submitted its report for

approval by Protection Sub Committee.

4.1 ENERGY ACCOUNTING: Availability Based Tariff (ABT) has been implemented in Southern

Region w.e.f. 1st January 2003. Consequently, accounting of energy for the

SR grid is being done by SRPC Secretariat regularly in line with CERC

guidelines / directives. The energy accounting involves preparation of

weekly UI, Reactive Energy Accounts and monthly Regional Energy

Accounts.

4.1.1 Weekly UI and Reactive Energy Accounts:

4.1.1.1 In line with the order of CERC, weekly accounts of Unscheduled

Interchanges (UI) and Reactive Energy are to be prepared and issued by

SREB/SRPC Secretariat every week in a time bound manner. Under the

ABT regime, each day is divided into 96 time blocks of 15 minutes each.

The schedules of generation by each Inter State Generating Station (ISGS)

and drawals by each beneficiary constituents for each time block is

compared with their actual generation / drawal for each block (computed

from the block wise reading of SEMs on all feeders). The charges for

deviation between actuals and schedules are computed on the basis of

frequency linked UI rates stipulated by the CERC from time to time. The

34

weekly UI accounts are compiled from the block wise data for all the 7

(seven) days ( Monday to Sunday ) of a week.

4.1.1.2 Weekly Reactive Energy account is prepared from the reactive

energy injected / drawn by the constituent beneficiaries with reference to

prevailing voltage conditions. Incentives for reactive energy injection at low

voltage and drawals during high voltage conditions and penalty for reactive

energy drawal at low voltage and injection during high voltage conditions

are levied at rates specified by CERC. The Reactive Energy account is also

compiled, like UI accounts, from the SEM readings every week.

4.1.1.3 UI and Reactive accounts were prepared and circulated to SR

constituents on weekly basis, as per the provisions of ABT orders and in

pursuance of CERC directions, with the soft copies of the computed files

uploaded to website so as to enable downloading by the SR constituents.

4.1.2 Monthly Regional Energy Accounts (REA)

4.1.2.1 The monthly REA, issued by SRPC, gives the details of energy

scheduled by beneficiary constituents from ISGSs within and outside the

region. The REA enables the Central Power Utilities to raise the bills on

beneficiaries for charges relating to capacity, scheduled energy, incentives,

transmission, RLDC etc. The monthly REAs, inter-alia comprise details on

the following:

i. Computation of Availability and PLF of thermal ISGSs covered by ABT.

ii. Energy scheduled to constituent beneficiaries from ISGSs for payment of energy charges.

iii. Energy scheduled by beneficiaries from ISGSs beyond target PLF for the purpose of payment of incentives to ISGS.

35

iv. Computation of weighted average percentages for the purpose of payment of Regional Transmission charges and RLDC charges.

v. Details of Intra-regional and Inter-regional scheduled bilateral exchanges and wheeled energy on short term open access.

vi. ESCOM / DISCOM wise details for Payment of Capacity / Energy charge and Incentive, wherever applicable.

4.1.2.2 The provisional REA for the current month and the final REA for the

previous month were issued latest by the 6th of each succeeding month.

4.2 UI CHARGES FOR INTER-REGIONAL EXCHANGES WITH

WESTERN & EASTERN REGIONS

4.2.1 At the time of implementation of ABT in SR, viz. 1.1.2003 it was

decided that the UI for inter-regional exchanges with WR will be settled at

the rates of the respective regions, i.e the UI receivable by the exporting

region and the UI payable by the importing region will be at their respective

frequencies. The difference amount between UI payable by the importing

region and receivable by the exporting region will be shared at 50:50 by the

two regions.

4.2.2 In the case of Eastern Region, the weekly UI accounts for inter-

regional exchanges between ER & SR are being prepared w.e.f. 1st April

2003, viz. the date of implementation of ABT in Eastern Region. EREB vide

their communication dated 1st April 2003 had intimated that UI for ER-SR

exchanges will be calculated at ER frequency only and accordingly, the UI

charges for inter-regional exchanges between ER and SR were being

computed at Eastern Region frequency. Subsequently, EREB proposed

vide letter No. EREB/COM-II/GEN/2004/ 2736-41 dated 28th May 2004 that

inter-regional UI between ER & SR be on respective regional frequencies.

EREB’s proposal was considered by SREB in a Special meeting of TCC

36

held on 23rd

August 2004. On the recommendations of TCC, the proposal

was agreed to by SRE Board in the 136th meeting and implemented with

effect from 6th September 2004, for which EREB’s concurrence was also

conveyed.

4.2.3 In view of the above, for exchanges of UI power with ER as well as

WR, amounts corresponding to respective regional frequencies are being

charged. The difference amount between UI payable by the importing

region and receivable by the exporting region were shared at 50:50 by the

two regions.

4.3 MEETINGS OF THE COMMERCIAL COMMITTEE

222nd

meeting of Commercial Committee of SREB was held in April

2006.Subsequently,Southern Regional Power Committee (SRPC) was

established and in line with Conduct of Business Rules, 2006 of SRPC,

Commercial Sub- Committee was reconstituted with representation from

member constituents of SRPC. Meeting of Commercial Sub-Committee of

SRPC were conducted in line with the provisions of revised Indian

Electricity Grid Code (IEGC) issued by Central Electricity Regulatory

Commission (CERC), effective from 1st April 2006. Accordingly, 1

st and 2

nd

meeting of Commercial Sub-Committee were held during the year 2006-07,

for audit of regional UI account and regional reactive account for the period

from 01.04.2006 to 03.09.2006.

Reverse power protection at Kaiga generating station:

Whenever the power flow gets diverted towards Kaiga due to loss

of evacuation lines between Nagjhari and Hubli stations, the increased

power flow on Kaiga – Guttur lines which are operating at 220kV level at

present, results in overloading of these lines with added generation of

42

Nagjhari, Kadra & Kodasalli generating stations and was resulting in

cascade tripping of Kaiga – Guttur lines most of the times.

Thus Kaiga gets islanded along with the above hydel generating

stations and the Units at Kaiga were tripping on loss of evacuation lines.

Earlier Kaiga was provided with a protection scheme to trip Kaiga – Kadra &

Kaiga – Kodasalli lines by sensing over load conditions on Kaiga – Guttur

lines. However the scheme failed to operate certain times due to racing of

relays.

Now Kaiga have implemented an additional protection scheme at

Kaiga generating station so as to trip 220kV Kaiga – Kadra & Kaiga –

Kodasalli lines, whenever the reverse current exceeds 600 amps for 1.0

sec. or 900 amps for 0.2 sec on these lines due to diversion of power flow

from Nagjhari, Kadra & Kodasalli generating stations towards Kaiga and

thus tripping of Kaiga – Guttur lines and islanding of Kaiga generating

station could be avoided.

Selective tripping scheme at Nagjhari generating station:

Whenever 220kV Nagjhari– Hubli lines 1, 2, 3 & 4 trips, it was

resulting in diversion of power flow from Nagjhari, Kadra & Kodasalli

generating stations towards Kaiga and leads to tripping of Kaiga – Kadra &

Kaiga – Kodasalli lines on reverse power protection provided at Kaiga. This

further results in islanding of the Units at Nagjhari, Kadra & Kodasalli

generating stations and trips due to lack of evacuation lines. KPCL have

implementing a scheme to trip the selected generators at Nagjhari

generating station by sensing power flow levels on Nagjari – Kodasalli lines

so as to limit the power flow on these lines towards Kaiga and thereby

avoid the tripping of Kaiga – Kadra & Kaiga – Kodasalli lines on reverse

power protection at Kaiga and which would in turn help in avoidance of total

loss of generation at Nagjhari, Kadra & Kodasalli generating stations. The

scheme helps in minimizing further disturbances and in improving the

system security of Southern Regional grid.

Power relays are installed on Nagjhari – Kodasalli line. Whenever

export through this line is more than 150 MW and less than 250 MW unit

1,2,4 & 5 trips sequentially with 0.1, 0.2,0.3and 0.4 seconds delay

43

respectively. If export is more than 250 MW unit 3,6 trips simultaneously

with 0.1 delays.

5.5 ISLANDING SCHEMES IN SOUTHERN REGION

Due to relatively even distribution of load and generation, the

islanding schemes are provided only in TN system, as an ultimate backup

during very low frequency conditions in Southern Regional grid. In few other

generating stations in the Region, the generators go on house load under

low frequency conditions. The details of the islanding schemes and house

load operation of generating units available in SR grid is furnished in the

5.6 DATA FOR MERITORIOUS PRODUCTIVITY AWARD:

The daily peak hour generation data of the thermal power stations

of Southern Region were collected from the power station authorities on

completion of every calendar month. The data were verified, compiled and

forwarded to OM Division, CEA, New Delhi for consideration for the

meritorious productivity award. The data on planned maintenance schedule

and actual maintenance taken up on the thermal units of Southern Region,

during the year 2006 - 2007 were also collected from the power station

authorities and compiled and sent to OM Division, CEA, New Delhi for

consideration of thermal stations for the award.

5.7 SYSTEM STUDIES:

The System Studies Sub Committee in which all the members of

SRPC represented is entrusted with the task of carrying out studies for

assessing quantum of capacitor requirement in the region, operational load

flow studies or any other technical studies referred by the SRPC/TCC.

Power System Studies for assessment of shunt compensation

required in the Regional grid is done for the annual peak load conditions.

The capacitor requirement is assessed with a view to maintain system

voltage at all the buses in the range of 0.90 to 1.05 per unit. The results of

the studies are brought out in the form of a report, which forms basis for the

constituents in planning the capacitor installation programme in their

respective systems.

During the year 2006-07, 24th meeting of System Studies Group

and 1st meeting System Study Sub-Committee was held on 19.04.2006 and

28.07.2006 respectively to finalise the capacitor requirement for the year

2006-07. The Report on the requirement of Shunt Compensation for March

2007 conditions was issued during August 2006. Action was also initiated to

assess capacitor requirement for the year 2007-08. In this connection,

preliminary data was collected from the constituents for conditions

prevailing on 29.03.2006 at 19:00 hrs in Southern Region. Base Case

45

Studies were carried out and circulated to the members of the System

Study Group for their comments.

The Power Map of Southern Regional Grid showing all 400 kV and

220 kV lines including all the inter-state / inter-regional lines was

periodically updated.

5.8 POWER SYSTEM STABILIZER TUNING:

In the 136th SRE Board meeting held at Hyderabad on 9

th

November 2004, the Board agreed to the carrying out of analytical studies

related to PSS tuning in SR and for forming a core group for this purpose.

For funding of these studies a tentative amount of Rs. 10 lakh, to be shared

equally by all the constituents was approved. The scope of the analytical

studies, among others, was to suggest need or otherwise, of PSS tuning of

the generators in SR. It was approved that the studies could be carried out

either through IISc, Bangalore or IIT, Mumbai, who carried out the studies in

case of WR, as per the needs.

In this context, IISc, Bangalore was approached. They agreed to be

associated for carrying out the analytical studies and also suggested for

involving Prof. R. Ramanujam of Anna University, Chennai and personnel

from CPRI Bangalore.

The core group for PSS tuning in SR was formulated and the first

meeting was core group was held 4th April 2005 in conference hall of SREB

wherein constituents agreed to provide all the relevant data for the studies.

An Interaction between Member Secretary, SRPC and Prof. R.

Ramanujam of Anna University, Chennai was held on 19.05.2006. Prof. R.

Ramanujam suggested the following methodology for doing the study for

PSS tuning in SR:

o Identify two to four base cases to reflect the operating conditions of

SR

o One to two contingency analysis on each base case to be done

46

o Eigenvalue analysis for each base to identify the least damped

mode. If any one of the rotor modes are very close to imaginary

axis then PSS is suggested

o Arrive at PSS parameters for each case and freeze on the one that

is best compromise for all cases identified above

o Perform Transient Stability analysis runs with PSS to check for

large-signal performance.

Further interaction is going on between IISC Bangalore and SRPC

secratariat.
