浅谈小浪底水力发电厂母线运行方式改变后的影响

Influence of Busbar Operation Mode Change on Xiaolangdi Hydropower Plant

为提高电网系统稳定、降低母线及线路短路电流、优化电网潮流,以小浪底水力发电厂为例,将220kV四段母线由合环运行改变为4段独立运行,分析了母线运行方式变化后豫西电网潮流特性及对机组运行方式、设备的影响,并采取相关预控措施。

Taking Xiaolangdi Hydropower Plant for an example, the closed-cycle operation mode of 220 kV busbar is changed to four parts for improving the stability of power system, reducing short-circuit current and optimizing power flow. And then, it analyzes the influence of changed busbar operation mode on the power flow feature, generators opera tion mode and device of Western Henan Province. Finally, some relevant control measures are put forward.
