Electric power voltage control system and control method thereof

Abstract

The invention discloses an electric power voltage control system and a control method thereof, and belongs to the technical field of electric power voltage control. The electric power voltage controlsystem comprises a background monitoring server, a data collection unit and a reactive adjustment apparatus; the background monitoring server and a data storage server perform power grid voltage regulation and control data storage / reading through the Internet; the background monitoring server comprises a data translation unit, a data classification unit and a data analysis unit; the data collection unit is connected with the background monitoring server; the data collection unit is mounted on a power grid output circuit; the data collection unit comprises a camera, a voltage detection module and a current detection module; the reactive adjustment apparatus and the background monitoring server complete remote data signal transmission through a remote control interface; and the output end ofthe reactive adjustment apparatus is connected with a transformer tap clamping head of the transformer. By virtue of the electric power voltage control system, electric energy quality can be safeguarded, power transmission efficiency can be improved, network loss is lowered, and electric power stable operation and economic operation can be realized.

Description

technical field [0001] The invention belongs to the technical field of electric voltage control, and in particular relates to an electric voltage control system and a control method thereof. Background technique [0002] With the rapid development of social economy and the continuous improvement of people's living standards, users have also put forward higher requirements for voltage quality. The reactive power compensation and reactive power balance of the power system are the basic conditions to ensure the voltage quality. Effective voltage regulation and reactive power compensation can not only improve the voltage quality, but also improve the stability and security of the power system, and give full play to the economic benefits of the power grid. [0003] At present, although some substations have achieved automatic control of voltage regulation and reactive power compensation, most substations are still manually adjusted and controlled, which has obvious disadvantages...

Problems solved by technology

[0003] At present, although some substations have realized the automatic control of voltage regulation and reactive power compensation, most substations are still manually adjusted and controlled, which has obvious disadvantages: it increases the monitoring and operation workload of operators; Reasonable adjustment methods lead to the inability of the adjustment equipment to be fully and reasonably utilized; the operator does not adjust in time, and the station-side control equipment is only beneficial to the secondary voltage of the substation, and the reactive power has no meaning for the optimization of the entire network. If no voltage is added, blocking will occur Side effects of transformer tap regulation
