轨道的长度在力量系统为敏感分析方法的雇用作为功能被建议短暂稳定性分析。它到差错空地时间的敏感比精力功能或距离功能的高大约 10 倍。当精确性被维持时,集成的时间被归结为不到 3 s。提供参数限制能也被用来。WSCC 4 机器系统和新英格兰系统上的模拟在短暂稳定性分析验证轨道长度的敏感的有效性。
The length of the trajectory is proposed as a function for the employment of the sensitivity analysis method in power system transient stability analysis. Its sensitivity to the faultclearing time is about 10 times higher than that of the energy function or the distance function. The integrating time is reduced to less than 3 s while the accuracy is maintained. It can also be used to provide parameter limits. Simulations on the WSCC 4 machine system and the New England system verify the effectiveness of sensitivity of trajectory length in transient stability analysis.
