Title: Self-excited reactive power compensator
Inventor: YOSHIDA TAKESHI
IPC: G05F1/70
Filed: 1995-03-27
Abstract: PURPOSE: To eliminate the power factor improving capacitor while avoiding voltage rise upon stoppage of load by compensating the reactive power flowing out from a load to the system when the instantaneous value of reactive power of the load is lower than a predetermined value thereby improving the power factor on the system side. CONSTITUTION: When a self-excited var compensator 7 is operated, a reactive power operating section 5 operates the reactive power of a load 1 based on the current and voltage thereof. When a power factor improving section 8 detects that fluctuation of the load 1 is low by detecting the instantaneous value of reactive power thereof, operational capacity of the war compensator 7 is also low during that interval. Consequently, a bias signal for supplying phase lead reactive power is added to the output signal from an inverter 4 and excess phase lead reactive power is fed from the var compensator 7 to a system bus 2 thus compensating for the reactive power flowing out from a load 1 to the system and improving the power factor on the system side.
