摘要

新疆与西北主网750 kV联网通道上配置了分级式可控高抗(SCSR)

需要将SCSR纳入电网自动电压控制(AVC)中并实现SCSR与电网其他无功设备的协调控制。文中提出了一种通过AVC对750 kV电网SCSR进行自动调节控制的新方法。该方法在考虑传统的无功电压自动控制功能的基础上

同时考虑电网安全对SCSR预留容量的需求

协调其他常规无功补偿设备使SCSR在稳态运行时预留出一定的无功容量

从而满足稳态下电压合格和暂态扰动下电压控制的要求。该方法已在西北电网AVC系统中得到应用

满足了750 kV新疆与西北联网通道SCSR的自动控制要求。

Abstract

The stepped controlled shunt reactor (SCSR) has been configured in the Xinjiang-Northwest 750 kV grid channel

which requires taking into account the coordination between SCSR and other traditional devices when performing automatic voltage control. As a solution under the new circumstances

a new method is put forward which not only makes full use of the AVC’s fundamental optimization for reactive power and voltage

but also takes the safety requirement on the SCSR’s reserved capacity into account by coordinating with other traditional reactive power compensation utilities

thus ensuring safe and economical grid operation. An actual system based on the method is studied and applied in the AVC control of 750 kV grid channel between Xinjiang and Northwest China

which has proven feasible and efficient.
