| 摘 要： | 本文将ＥＥＡＣ法与时域法相结合用于电力系统的暂态安全分析。用基于简单模型的极块的ＥＥＡＣ法扫描预先指定的事故集，求出各种情况下的稳定裕度，把明显稳定的情况过滤掉，剩下的情况再用时域法详细仿真。这种两方法的结合，可以快速准确地判断系统的暂态稳定性。

| Abstract: | The combination of step by step method and direct method on transient securite analysis (TSA) of electric power system is presented in this paper. It uses EEAC based on simplified method to scan the prothought faults aggregate, calculates each stability margin and filters the apparent stable cases. SBS is then used to simulate the rests in detail. This technique is tested on an IEEE 9 bus system. The results show that it is a powerful tool on TSA in power systems. |
