Patratu Thermal Power Station
• Panipat Thermal Power Station(PTPS) is governed by Haryana State Electricity Board.• Located at about 10 KMs away from• Panipat on Panipat-Assandh road near• the village Assan.• The total installed capacity at P.T.P.S is• 4*110 MW + 2*210 MW + 2*250 MW• (1360 MW).

Thermal Power Plant
• Thermal Power Stations require a number of equipments performing a number of complex processes with the ultimate aim to convert chemical energy of coal or oil to electrical energy.
• This involves the generation of steam in the boiler by burning coal.
• The steam in turn drives the turbine. The Turbo Generator coupled with the turbine produces electricity which is stepped up with the help of transformers and is fed into grid station through transmission lines.

Basic Idea of ElectricityGeneration
Coal is unloaded by electric traction system at Coal Yard Coal is crushed to finer pieces of order 20 mm
Pulverization of Coal
Coal is send to furnace with the help of FD fan
Steam is generated at 540°C and 135 kg/sq.m
Steam is send to Super heater
Superheated steam is send to turbine
Production of Electricity by the generator coupled with

Instrumentation In Thermal PowerPlant
When the balance is disturbed, all the process variables deviate from their normal valves thus creating the necessity for the following:- i)Instruments : To measure and indicate the amount of deviation. ii)Automatic Control: To correct the deviation and bring back system to normal iii) Annunciation : To warn about the excessive deviations, if any. iv) Protection : To isolate the equipments process from dangerous operating conditions cause due to such excessive deviations.

SELECTION CRITERIA OFINSTRUMENTS
• Required accuracy of measurement• Range of measurement• The form of final data display required• Principle of working• Cost• Calibration and repair facilities required/available• Layout restrictions• Maintenance requirements/availability

Temperature
The degree of hotness and coldness measured on the definite scale.• Methods of Temperature Measurement• Resistance Temperature Detector(R.T.D)• Thermocouple
![Page 13: Patratu thermal power ppt](https://reader036.vdocument.in/reader036/viewer/2022081416/5585b2cad8b42af75f8b45a4/html5/thumbnails/13.jpg)
Resistance TemperatureDetector
• Resistance of certain metals changes as the temp. changes as per formula given below :- Rt=Ro(1+wt)• Where Rt=Resistance at temp. to be measured.
Ro=Resistance at 0 degree C. w=Temp. coefficient of res. Thermometer metal t=Temp. to be measured.• Mainly three metals copper, nickel and platinum
are used as RTD.

Thermocouple
• It consists of a pair of wire of different materials.
• Wires are joined at both ends one junction is kept at a high temp.called hot junction and the other is kept at a fixed at lower temp.called cold junction. Due to which emf is setup in the ckt known as Thermo emf.
