Description
technical field [0001] The invention belongs to the technical field of power system operation control, and relates to a reactive power compensation system and a control method thereof. Background technique [0002] The reactive power compensation device is used to supplement the lack of reactive power in the grid, improve the power factor, ensure the safe operation of the power supply system, reduce power loss and save power. Reactive power compensation equipment is very important for some equipment with low power factor and large power consumption. This is for the power system, if reactive power compensation equipment is used in such an environment, improving the power factor has significant economic benefits. At present, in the reactive power compensation system of the power system, there are not many reactive power compensation devices with compensation inductance to make the compensation capacitor continuous.
