A networking method of an intelligent modular reactive power compensation device

Abstract

An intelligent modular reactive power compensation device and a networking method belong to the technical field of power system power quality control. The intelligent modular reactive power compensation device comprises a cabinet body, a multifunctional digital display monitoring instrument, capacitor switching indicator lamps, an isolating switch, a current transformer, a power surge protector, and intelligent power capacitors. The power surge protector and the intelligent power capacitors are connected with a three-phase power source through the isolating switch. A voltage sampling loop of the multifunctional digital display monitoring instrument is connected with a secondary side of the isolating switch, and a current sampling loop of the multifunctional digital display monitoring instrument is connected with a secondary side of the current transformer. A signal lamp output loop of each intelligent power capacitor is connected with the corresponding capacitor switching indicator lamp. The intelligent modular reactive power compensation device provided by the invention has a simple wiring structure, is spiced in a modular and combined mode, and is intelligent and integrated, and intelligent autonomous networking control can be realized both through operation of a single device and through parallel operation of multiple devices.
