增强电网安全的思路

Thinking for Enhancing the Security of Power Grid

世界范围内的多次大面积停电事故越来越引起人们对电网安全稳定的关注。对电网进行实时的稳定评估,提供紧急控制策略,实现电网安全稳定性的在线监测和预警是位于"三道防线"之前的一个重要分析工作。随着电力市场改革的深入发展,如何提高市场环境下大电网的安全性也是需要深入讨论的问题。对电网安全稳定性的在线监测和预警以及市场条件下的处理输电阻塞等两个方面内容进行研究,为大电网安全防治提供有效的研究思路和初步的解决方案。

Several wide - spread power blackouts have drawn the increasing concerns about the security and stability of power grid around the world. Real - time stability assessment of power grid, online monitoring and forewarning which provide emergency control strategy to achieve the security and stability of power grid are an important analysis prior to ＂three lines of defense＂. How to improve the security of whole grid under the electricity market is also an issue that needs a detailed discussion. The researches about online monitoring and forewarning for the security and stability of power grid and dealing with transmission congestion under market conditions are introduced, which provides an effective research idea and a preliminary solution for the security control of whole power grid.
