what is the difference between fc-tcr and tsc in facts

Answer Posted / swapnil

basically fc tcr(fixed capacitor-thyristor controlled reactor)in this device the Q value of the capacitor is constant as the capacitor is a fixed one and we can get the required reactive power by varying the Q of inductor using thyristors.
Q(REQ)=QCAP-QTCR
FOR TSC(THYRISTOR SWITCHED CAPACITOR) here we can vary the thyrisors in only two ways ie full or partial conduction.
but in tcr we can vary the thyristors angle from 0-180(deg)
usally a combination of tcr and tsc,tsr makes a svc
As well as TSC TCR can work in Both region Capacitive to Inductive
