Abstract:
There are provided methods, devices, and systems relating to discharging thyristor-switched capacitors. For example, there is provided a method for discharging a first capacitor, a second capacitor, and a third capacitor. Each of the capacitors is coupled to respective phases of a transmission line. The first capacitor and the third capacitor are each coupled to their respective phase of the transmission line via a pair of anti-parallel thyristors, and the second capacitor is coupled directly to another phase of the transmission line with no thyristors therebetween. The method can include determining whether an angle of a voltage on the transmission line is within a threshold angle. Further, the method can include discharging the first, second, and third capacitors when the angle is within a threshold angle and the threshold angle is any value from a predetermined set of threshold angles.
