Problems solved by technology

[0004] Traditional flexible AC power transmission technologies such as TSC, SSSC, STATCOM, UPFC and other related equipment architectures can significantly enhance the system voltage stability. The disadvantage is that it can only control a single line, with limited adjustment ability and high cost, which limits its popularization and application.

Abstract

The present application discloses a voltage stabilization control device, method, equipment and medium, the device comprising: a power flow router and a coordination controller; the power flow router is used to transmit the measured voltage signal in the line to the coordination controller, and The line power and voltage are controlled at specified values; the coordination controller is used to analyze the received voltage signal and send control instructions to the power flow router. In this application, the power flow router and the coordinating controller are configured in the power transmission and distribution system, and the coordinating controller controls the power flow router, so as to improve the stability of the system.

Description

technical field [0001] The present application relates to the technical field of power grid voltage control, and in particular to a voltage stability control device, method, equipment and medium. Background technique [0002] With the increase of power grid load and the continuous improvement of the penetration rate of new energy power generation, severe challenges have been brought to power system dispatching and voltage stability, and the problem of source-network coordination has become more and more prominent. In addition, due to the volatility and uncertainty of new energy power generation output, the system needs to be flexible enough to accommodate a high proportion of new energy power generation, and at the same time have a strong transmission capacity to meet the growing load demand. In recent years, the curtailment rate of wind and light in the three north regions of my country's large-scale new energy base has been high. In addition to the problem of insufficient ...
