Problems solved by technology

[0004] However, through the AVC system, the reactive power compensation equipment group is randomly put into the busbar for reactive power compensation. Although the control of the switching of the reactive power compensation equipment group is solved, the AVC system is based on the random principle when the reactive power compensation equipment group is put into operation. The selection of the input reactive power compensation equipment group is prone to the problem that the running time of a certain reactive power compensation equipment group is longer, and the running time of some reactive power compensation equipment groups is shorter, thereby reducing the reactive power compensation of long-term work. The working reliability of the equipment group is not conducive to the safe and stable operation of the distribution network

Abstract

The invention discloses a reactive compensation equipment operation method and device, equipment and a storage medium. The method is used for realizing on-off control of multiple groups of reactive power compensation equipment on the same group of buses, and comprises the following steps: respectively acquiring the accumulated operation time of each reactive power compensation equipment, wherein the accumulated operation time is the time when each reactive power compensation equipment is put into operation; determining the range of the accumulated operation time, wherein the range is the difference between the maximum value and the minimum value of the accumulated operation time; and adjusting the priority of each reactive power compensation device in operation based on the range. The accumulated operation time of each reactive power compensation device is obtained, then the range of each accumulated operation time is calculated, and the priority of the reactive power compensation devices in operation is adjusted based on the range, so the accumulated operation time of the plurality of reactive power compensation devices can be more balanced; the problem that the system stability is reduced due to the fact that the accumulated operation time of a single reactive power compensation device is too long is solved.
