Abstract

The invention provides a three-joint-regulation reactive power compensation system. The three-joint-regulation reactive power compensation system comprises a low-voltage transformer-area reactive power compensation device, a transmission line reactive power compensation device and a transformer substation reactive power compensation device, wherein the low-voltage transformer-area reactive power compensation device, the transmission line reactive power compensation device and the transformer substation reactive power compensation device are respectively connected with a wireless receiving terminal; the wireless receiving terminal is connected with a base station through an antenna; the base station and a gateway are connected for data synchronization; and the gateway is connected with a reactive joint-regulation main station. The three-joint-regulation reactive power compensation system has the advantages that a smart distribution network reactive voltage automatic control system communicates with a distribution network reactive power compensation comprehensive measurement and control device through a wireless encryption private network, remote sensing and remote signaling data of each node are acquired, reactive voltage optimal calculation is performed, a smart reactive voltage optimal control system based on a wireless private network can monitor reactive terminals which are distributed in various regions and can perform dynamic and local compensation, voltage qualification and power factor qualification are ensured, and grid loss is reduced.

Description

technical field [0001] The invention relates to a three-stage joint debugging reactive power compensation system for power grids. Background technique [0002] In the prior art, it is known that in the existing rural power grid, there are dual problems of voltage instability and excessive network loss. Among them, with the development of the rural economy and the implementation of the "Home Appliances to the Countryside" campaign, the power load of the rural power grid has shown explosive growth in recent years. In this case, the phenomenon of voltage instability has seriously restricted the power of the rural power grid. Normal power supply. [0003] In-situ compensation for the power supply station area. According to the actual load conditions, thyristor (or compound switch) switching capacitor (TSC) can be used in the occasion of low power factor, low voltage and three-phase basic balance to ensure the long-term service life of the equipment; in the case of serious thre...
