基于串联电抗器的广东电网短路电流抑制方案

结合国内外大电网运行现状与经验，介绍串联电抗器在短路电流抑制方面的应用及主要问题，并分析广东电网未来几年短路电流的发展趋势。结果表明，过高的短路电流已严重制约方式安排，显著削弱电网可靠性。结合广东电网实际情况，对短路电流超标站点的相关线路进行串联电抗器接入灵敏度分析，归纳出串联电抗器在广东电网的短路电流抑制效果并提出两点串联电抗器配置建议，在此基础上给出适用于广东电网的串联电抗器配置的推荐方案。

Restriction Scheme for Short-circuit Current in Guangdong Power Grid Based on Series Reactor

Combining running status quo and experiences of large power grids at home and abroad,application and main problems of series reactor in restricting short-circuit current were introduced and development trend of short-circuit current of Guangdong power grid in future years was analyzed.Results indicated over high short-circuit current would seriously re-strict way arrangement and obviously weaken power grid reliability.Combing physical truth of Guangdong power grid,accessing sensitivity of series reactors on relevant lines of stations with excess short-circuit current was analyzed.Restriction effect on short-circuit current in Guangdong power grid of series reactor was concluded and two configuration suggestions were proposed.On the above basis,recommendation scheme suitable for series reactor configuration in Guangdong power grid was put forward.
