Abstract

The invention discloses a reactive compensation equipment switching method and device. The method comprises the following steps: counting respective continuous operation time of all reactive power compensation equipment in operation in a transformer substation; and when the continuous operation time of the reactive power compensation equipment in operation reaches a first time threshold value, if the reactive power compensation equipment in operation is quitted and the characteristic parameters of the transformer substation do not exceed the limit, quitting the reactive power compensation equipment in operation. According to the embodiment of the invention, alternate operation of the reactive compensation equipment can be realized, faults caused by long-time operation of the reactive compensation equipment are avoided, and the operation safety of a power grid system is improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of power systems, and in particular to a method and device for switching reactive power compensation equipment. Background technique [0002] In the power grid system, in order to maintain reactive power balance and voltage stability, each substation is equipped with a certain number of reactive power compensation equipment. Existing power grid system scheduling is realized through the AVC system (Automatic Voltage Control, automatic voltage control system), specifically through the scheduling automation SCADA system (Supervisory Control And Data Acquisition, data acquisition and monitoring control system) to collect the busbars of each substation and power plant Centralized monitoring, analysis and calculation of key measurement data such as voltage, and automatic switching of reactive power compensation equipment according to demand. However, the existing control strategy lacks a rot...
