FAQs about Advantages and disadvantages of thyristor switched capacitors

What is a thyristor switched capacitor?

It consists of a power capacitor connected in series with a bidirectional thyristor valve and, usually, a current limiting reactor (inductor). The thyristor switched capacitor is an important component of a Static VAR Compensator (SVC), where it is often used in conjunction with a thyristor controlled reactor (TCR).

What happens if a thyristor valve is switched off?

In the off-state voltage, the TSC should be off and there is no current flow in the thyristor-switched capacitor. The voltage is supported by the thyristor valve. If the TSC is switched off for a long time, then the capacitor will fully discharge and the thyristor valve will experience the AC voltage of an SVC bus bar.

Why does a thyristor valve have a lower impedance than a capacitor?

The controlled reactor has a significantly lower impedance than the capacitor so that when the thyristor valve is fully conducting, the overall impedance of the capacitor section becomes inductive; the current through the reactor is greater than the line current and the capacitor current is smaller.

How thyristor switched capacitor is used in EHV lines?

The thyristor switched capacitor is used in EHV lines for providing leading VARs during heavy loads. The current through the capacitor can be varied by controlling the firing angles of back to back thyristor connected in series with the capacitor.
