ABSTRACT:
In an alternating current electric power system of the type subject to rapid load voltage regulation as a result of variations in reactive load current, reactive load current compensation is provided by fixed capacitors and inductors in parallel with the load, the inductors being in series with static switches which are phase controlled to continuously maintain the net reactive compensating current substantially equal and opposite to the reactive component of load current. Compensation control determines firing time of static switches in accordance with the magnitude of reactive load current. The compensation control includes means rapidly responsive to rapid current disturbances. In one embodiment, the compensation control includes devices for continuously sensing the phase and magnitude of the reactive load current. In another embodiment, the compensation control includes devices for sensing the phase and magnitude of the reactive load current 12 times per cycle of source frequency.
