AI Customer ServiceA thyristor-switched capacitor (TSC) is a type of equipment used for compensating reactive power in electrical power systems. It consists of a power capacitor connected in series with a bidirectional thyristor valve and, usually, a current limiting reactor (inductor).
Policies and ethics Thyristor switched and controlled series capacitor systems were developed in the late 1980s to enable increased load carrying capacity of existing high voltage transmission lines. Thyristor controlled series capacitors (TCSC) would insert a variable series impedance...
The capacitor will then discharge through the thyristors and the reactor. The effect of this is that the capacitor will appear to be smaller, i.e., it will have a higher impedance. This increases the apparent degree of series compensation for the line thereby boosting the current ow through the line.
Thyristor-controlled series capacitors (TCSC). Fig. 28.17 presents the current and voltage waveforms in the TCSC, showing that although there is a large amount of harmonics in the capacitor and reactor currents, capacitor voltage is almost sinusoidal.
Thyristors are used in power control circuits to regulate the amount of power flowing through a circuit. They are used to switch on and off loads such as motors, heaters, and lights. The amount of power flowing through the circuit can be controlled by varying the pulse width of the gate signal.
The Thyristor Switched Parallel Capacitors (TSPC) circuit belongs to the Controlled Series Capacitor (CSC) circuits. Those circuits have been used in power transmission lines to correct the power factor and improve the performance of the electrical system.
