Problems solved by technology

[0003] The current voltage stabilization device for distribution network lacks the function of remotely receiving control commands and transmitting local real-time data to the remote client. At the same time, the device lacks a certain alarm mechanism, which cannot timely respond to possible excessive temperature or If the alarm is too low or the voltage is unstable, it will reduce the stabilizing effect of the device on the voltage, affect the normal operation of other devices, and increase the possibility of safety accidents

Description

technical field [0001] The invention relates to the technical field of distribution network, in particular to an automatic voltage regulator based on a control strategy for voltage stability operation of the distribution network. Background technique [0002] The distribution network refers to the power network that receives electric energy from the transmission network or regional power plants and distributes it locally through power distribution facilities or to various users step by step according to voltage. It is composed of overhead lines, cables, towers, distribution transformers, and isolating switches. , reactive power compensator and some ancillary facilities, etc., which play an important role in distributing electric energy in the power network. [0003] The current voltage stabilization device for distribution network lacks the function of remotely receiving control commands and transmitting local real-time data to the remote client. At the same time, the device...
