Abstract

The invention discloses a ZigBee and RS485 communication mode based quick reactive compensation controller. The controller and an intelligent capacitance module quickly network and quickly exchange state data through the ZigBee wireless communication technology; a control instruction is distributed by RS485 communication, and the control instruction and a state acquiring instruction are performed synchronously, so that the total communication speed can be increased, and as a result, the purpose of quick compensating can be achieved. With the adoption of the controller, two communications can be performed synchronously; the control instruction and the state acquiring instruction are performed through different links, the intelligent capacitance module can be timely responded, so that the communication time can be greatly reduced, the compensation speed can be increased, and the reactive power compensation of a power grid can be quickly and effectively achieved.

Description

technical field [0001] The invention relates to a reactive power fast compensation controller, in particular to a reactive power fast compensation controller based on ZigBee and RS485 communication modes. Background technique [0002] The so-called reactive power compensation means that after installing reactive power compensation equipment such as shunt capacitors in the grid, it can provide reactive power consumed by inductive loads, reducing the reactive power provided by the grid power supply to the inductive load and transmitted by the line. The flow of reactive power in the grid can reduce the power loss caused by transmission of reactive power in lines and transformers, and can also be used to adjust the voltage of the grid and improve the stability of the grid. [0003] The existing connection methods between the controller and the smart capacitor module generally have two types: contact type and RS485 communication type. RS485 communication is a widely used connecti...
