电力系统暂态稳定影响因素的分析对电力系统暂态稳定性、电力系统的安全运行和暂态稳定预防控制都有着重要意义。影响电力系统暂态稳定的主要因素分别为故障类型、运行方式、微机保护的故障切除时间等。本文通过使用华中科技大学研发的WDT-III电力系统综合自动化试验台进行暂态稳定实验，并对获取的实验数据进行了分析研究，实验结果表明，三种因素对电力系统暂态稳定具有不同的影响。实验结果分析对提高电网暂态稳定分析具有一定的参考价值。

The analysis on the main factors impacting on power system transient stability is of significance for power system transient stability, power system security and the control of the transient prevention. The main factors of impacting on power system transient stability is the type of fault, relay operating time and operation mode, etc. In this paper, we used the appliance of WDT-III universal automatic power system which is designed by Hua Zhong Technology University, and analysied the data and the reason of experiment. The result of experiment indicates that the three elements should not be ignored. The analysis of experimental results have the certain reference value to improve power system transient stability analysis.
