安全自动装置在高压失稳电网中的配置方案研究

高压电网发生功角稳定、过载等问题时,会严重影响到电网的安全稳定运行,若不及时采取相应措施,轻者会导致元件受损或烧毁,重者甚至会导致整个或局部电网失稳、解列。本文以西北某省330、110kV区域电网为算例,针对高压电网中几种最为常见的安全稳定问题,提出了简单、可靠的解决措施和相应的安全自动装置配置方案。具有较强的实用性和较高的典型性。

Research on Configuration Scheme for Safety Automatic Device in Instable High-voltage Power Grid

The problems of high-voltage power grid,such as power-angle instability,overload,etc,will significantly affect the safety and stability of the grid.If lack of timely measures,it can lead a damage to the component,seriously it can also bring about an instability or splitting accident to a local or even a whole area power grid.This paper,taking the regional grid of 110kV and 330kV in a northwest province as an example,aiming at the most common problems of safety and stability in high-voltage grid,proposes a s...
