Abstract
There are provided methods, devices, and systems relating to discharging thyristor-switched capacitors. For example, there is provided a method for discharging the capacitors of a thyristor-switched capacitor (TSC) device coupled to a transmission line. The method includes determining whether an angle of a voltage on the transmission line is within a threshold angle. Further, the method can include operating the device in a discharging mode when the angle is within the threshold angle and the threshold angle is in a predetermined set of threshold angles.

A controller, comprising:
- a processor communicatively coupled to a device including (i) at least one of a pair of thyristors and (ii) a plurality of capacitors, the device being coupled to a transmission line;
- and
- a memory having instructions stored thereon, which when executed by the processor, cause the processor to perform operations comprising:
- determining whether an angle of a voltage on the transmission line is within a threshold angle;
- and
- operating the device in a discharging mode to discharge the capacitors when the angle is within the threshold angle and the threshold angle is in a predetermined set of threshold angles.
