Control of reactive power compensator
专利汇可以提供Control of reactive power compensator专利检索，专利查询，专利分析的服务。并且PURPOSE: To compensate for the reactive power of load by giving phase advance reactive power to the connecting point for power system through the reactance of reactive power generation power source unit by means of a forced commuatating type adjustable forward converter having an A.C. input point.
CONSTITUTION: To compensate for the reactive power of the load 2 connected to the power source system I, the pulse width modulation type power inverter 4 by which the DC voltage supplied from the forced commutating type adjustable forward converter 5 is converted into Ac output voltage having base amplitude proportional to the DC voltage and the same base phase as the system voltage and the forced commutating type forward converter 5 operated at advance phase angle are connected through reactor to the system. Using the composite value consisting of the reactive component of the output current base wave of inverter and the reactive component of lod current base wave as a target value, and also the reactive component of the input base wave of the forward converter as an actual value, the control angle of the forward converter is controlled by the control circuit 7 in order to compensate for the reactive power of load.
