东北和华北交流联网后电网内部暂态稳定水平变化分析

Theoretical analysis on effect of Northeast-North China Power System interconnection on transient stability levels of two power systems

着重对东北和华北交流联网后2网内部重要输电断面暂态稳定水平变化的主要原因进行理论分析,理论分析结果和对实际东北、华北交流互联系统的仿真结果从定性上看是一致的。

Northeast-North China Power System AC interconnection results in changes in transient stability levels of the two regional systems.This paper analyzes theoretically the causes for the changes.The theoretical analysis corresponds with the results of digital simulation.
