摘要
在结构保持模型的基础上分析了计及励磁调节器和调速器的单机无穷大系统的暂态能量在网络中的分布特点,以及暂态能量的分布与系统的暂态稳定性之间的关系,并推导出单机无穷大系统计及详细模型的网络暂态能量函数。仿真结果表明计及调节器的暂态能量在网络中的分布同样具有聚积性的特点,即全系统的稳定性问题的研究可以映射为网络局部环节稳定状况进行分析。
In this paper, the branch transient potential energy is studied to analyze the energy distribution over network and the transient stability of one-machine infinite-bus system with voltage regulator and speed governor. And the detailed branch transient potential energy function of one-machine infinite-bus system is derived. The simulation results on OMIB ( One Machine and Infinite Bus) demonstrate the effectiveness of the branch transient potential energy method with detailed model.
