FALSE TRIPS IN GAS POWER PLANT DUE TO TRANSIENT VOLTAGE VARIATION
Mahmoud Ismail Mehanna;
Abstract
The sudden isolation of a large combined cycle power plant in Al-Burullus, Kafr El-Sheikh city, Egypt with a capacity of 4800 MW will lead to a defect in the electric grid stability. This sudden isolation occurs due to Trip important sensitive loads in the Gas station of this plant (Fuel Gas Compressors and Auxiliary air compressor).
This thesis presents some of the published researches for power conditioning devices used for compensating the voltage fluctuation problem. (DVR) was selected to monitor the source voltage of these sensitive loads and compare it with the reference voltage. If any voltage drop is detected, this value is injected into the load side.
MATLAB/Simulink program is used to verify the effectiveness of this device in the compensation of the voltage sag with these loads in a duration less than 10msec. which is less than the trip setting of the load C.B.
