Abstract:A reasonable choice of the control strategy for reactive power compensation equipment is the key to the design and operation of reactive power compensation equipment. When the control strategy is not appropriate,problems such as reactive power over-compensation, sub-compensation, etc. will happen. Based on the operation data of a bulk terminal power grid, this paper analyzes the defects of control strategy for the power compensation equipment, and puts forward a reform plan. With a small investment, it can get a great transformation benefit.
