6 FAQs about [Thyristor adjustment capacitor]

What is a thyristor controlled series capacitor?

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...

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.

What is thyristor-controlled series capacitor (TCSC)?

Can a thyristor switch be used to bypass a capacitor?

It is impossible to obtain rapid or frequent bypassing and re-insertion of capacitor sections using conventional mechanically operated switchgear, but faster switching can be achieved using thyristor switches for one or more sections, Figure 41.37 (a).

How can a series capacitor be continuously controlled?

In this compensator, the equivalent value of the series connected reactor can be continuously controlled by adjusting the firing angle of the thyristors. As a consequence, this device presents a continuously controllable series capacitor. Various practical systems based on this concept are under operation around the world [13–15].

What is a thyristor switch?

It consists of the fixed series capacitive reactance XC and variable inductive reactance XL(α) and SW refers to the thyristor switches. The firing angle (α) is measured from the peak of capacitor voltage or the zero crossing of line current.
