改善开关特性 提高电力系统暂态稳定性

Improving Characteristic of Switing to Enhance Transient Stability of Power Systems

电力系统稳定性就是要保持发电机组输入与输出功率平衡。本文提出了对功率平衡起决定性作用的开关特性进行改善,使开关动态性能可响应发电机组电磁功率的改变,以保持功率平衡,从而提高电力系统暂态稳定性。

The stability of power systems depends on remaining the balance of input and output powers in generating—sets. The paper puts forward that improving the characteristic of switching, which play a determined role in power's balance, could make dynamic characteristic of switching response the change of electromagnetic power in generating—sets in order to remain the balance of power and enhance transient stability of power systems.
