摘要
提出了衡量单相接地故障选线方法性能的指标,对其中一种选线方法的性能指标进行了详细分析,给出了分析方法以及误判率的定量表示。结果表明,该选线方法的误判率与系统规模、信号处理电路噪声性能等密切相关。
The performance indexes for measuring the capability of fault line selection methods for single phase earth faults are proposed. Aiming at one of these methods, the performance indexes are analyzed emphatically and minutely. The analysing means and quantificational expression of the misjudgment rate are showed se- quentially. The results indicate that the misjudgment rate of this fault line selection method is closely related to the scale of electric power system, noise performance of the signal processing circuits, etc.
