The invention provides a reactive power compensation composite system for a substation and a control method thereof. The system includes a master control terminal, a first reactive power compensation terminal and a second reactive power compensation terminal. The master control terminal is used to obtain the amount of reactive power to be compensated on the bus of the substation, and to generate a first control command according to the amount of reactive power to be compensated. Send to the first reactive power compensation terminal and / or generate a second control instruction and send it to the second reactive power compensation terminal. Since there are two reactive power compensation terminals, and the first reactive power compensation terminal is provided with multiple reactive power compensation units, the master control terminal can control each reactive power compensation unit to be connected to or disconnected from the circuit as required. It has many practical advantages such as small classification, convenient installation, large available space, and easy management and maintenance. The second reactive power compensation terminal can fine-tune the reactive power compensation amount, so as to ensure that the busbar of the substation is always in the best operation. status, and can effectively reduce costs.
Description
technical field [0001] The invention relates to the technical field of power grid reactive power compensation, in particular to a reactive power compensation composite system for a substation and a control method thereof. Background technique [0002] In a modern society, electricity has become an indispensable factor in national life, and is closely related to the development of the national economy and the progress of science and technology. Nowadays, the requirements for power quality in all aspects of national life are constantly improving, and more and more new technologies are being applied. in the power system. In the power system, whether it is power transmission or power consumption, reactance is inevitable. Therefore, in the power grid, a large amount of reactive power loss will be generated while active power flows, which is a great hidden danger to the safety of the power system. [0003] Reactive power compensation is an indispensable part in substations. The ...
