摘要

在SVC装置处于运行模式

当电网发生大的扰动时能为系统提供快速的动态无功功率补偿

提高系统的电压稳定性。保护系统控制逻辑是SVC保护的核心

其正确整定是保证SVC在遇到故障时能够正确动作的前提。通过对SVC保护系统控制跳闸逻辑中的节点异常保护与温度保护进行深入分析

通过实例指出节点异常保护跳闸逻辑与温度保护控制跳闸逻辑存在设计缺陷并给予改进措施。能够给其他厂站根据自己的SVC具体使用情况对节点异常保护跳闸逻辑与温度保护控制跳闸逻辑进行深入研究提供借鉴

以保证SVC的正常运行。

Abstract

The SVC can

in case of operation mode and of big disturbance of power grid

provide fast dynamic reactive power compensation to the power system so to improve voltage stability of the power system. The control logics of protection system are the key technology of SVC

its correct setting is the premise to ensure correct action of SVC in case of encountering fault. In this paper

throughout deep analysis of by node abnormity protection and temperature protection in the control tripping logics of SVC protection system

it is pointed out by real example that abnormal protection tripping logics of node and the tripping logics of temperature protection have design defects and improvement measure for such defects are given

which can provide reference to the deep study of node abnormity protection control logic and the temperature protection control logic to specific application of other substations so to assure normal operation of SVC.
