What is the reactive power and how to control the reactive
power in power plant
Answer Posted / saleem pasha
reactive power will come in picture when ever the voltage
and current are not in phase in AC CIRCUITS,
POWER THAT CONTINOUSLY BOUNCE BACK AND FORTH BETWEEN SOURCE
AND LOAD IS KNOWN AS REACTIVE POWER , AND IS MEASURED IN VAR.
IN CASE OF POWER PLANT, SUPPLYING POWER TO INDUCTIVE LOAD
LIKE INDUCTION MOTOR WHICH REQUIRE REACTIVE POWER TO PRODUCE
MAGNETIC FIELD FOR THEIR OPERATION, IF AT ANY TIME THE MOTOR
RECEIVE LESS REACTIVE POWER FROM SOURCE THEN VOLTAGE WILL
SAGDOWN AND IT IS NOT POSSIBLE TO PUSH THE POWER DEMANDED
BY THE MOTOR , THEN IT BECOME NECESSARY TO SUPPLY OR
GENERATE REACTIVE POWER WITH THE HELP OF CAPACITOR BANK/OVER
EXCITED SYNCH MOTOR/THYRISTER CONTROL CAPACITIVE
INDUCTOR/VOLTAGE SOURCE INVERTER, IN THIS WAY WE CAN CONTROL
REACTIVE POWER.
