Abstract

The invention discloses a reactive compensation control method and device, a storage medium and equipment. The method comprises the following steps: obtaining the circuit parameters of a current three-phase circuit in real time, and calculating the capacitor switching parameters of the current three-phase circuit according to the circuit parameters; determining to switch a capacitor to the current three-phase circuit according to the capacitor switching parameter; and determining a target switched capacitor according to the operation time, the capacitor temperature and the switching times of the plurality of capacitors to be switched in the current three-phase circuit, and controlling the target switched capacitor to be switched into the current three-phase circuit. According to the operation time, the capacitor temperature and the switching frequency of the switching capacitor in the current three-phase circuit, the target switching capacitor is determined, so that the service time, the temperature and the service life of each capacitor are more balanced, the use frequency of the high-frequency capacitor is reduced, the service life of the capacitor is prolonged, and normal operation of a power supply system is ensured.

Description

technical field [0001] The present invention relates to the field of control and power grid, in particular to a reactive power compensation control method, device, storage medium and equipment. Background technique [0002] As a compensation device, the power capacitor reactive power compensator plays the role of improving the power factor of the power grid, reducing the loss of power supply transformers and transmission lines, improving power supply efficiency, and improving the power supply environment in the power supply system. Therefore, the power capacitor reactive power compensation device is in an indispensable and very important position in the power supply system. The power capacitor reactive power compensator completes reactive power compensation logic judgment according to the power factor of the power supply line, drives capacitor switching, and completes reactive power compensation. According to the specific situation of the three-phase reactive power, it is d...
