通过研究现有应用的“暂态综合判据法”和“信号源注入法”检测原理,发现这两种方法适用于配电网常见的中性点不接地和经消弧线圈接地系统,且动作准确性高于其他检测原理,应结合故障指示器的原理及网架结构的复杂程度,选择与配网相适应的检测原理及设备。然后通过对故障指示器的应用现状分析,给出了故障指示器系统自身功能扩展及该系统接入配电自动化系统的发展方向的建议。
通過研究現有應用的“暫態綜閤判據法”和“信號源註入法”檢測原理,髮現這兩種方法適用于配電網常見的中性點不接地和經消弧線圈接地繫統,且動作準確性高于其他檢測原理,應結閤故障指示器的原理及網架結構的複雜程度,選擇與配網相適應的檢測原理及設備。然後通過對故障指示器的應用現狀分析,給齣瞭故障指示器繫統自身功能擴展及該繫統接入配電自動化繫統的髮展方嚮的建議。

Studying the exsiting application “transient synthesis criterion method” and “signal injection method” detection principle,found that the two methods is suitable for the common distribution network neutral point grounding and arc-supptession coil ground system? And the accuracy is higher than other principle? We shoud combine the principle of fault indicator with the com-plexity of the space truss structure to select appropriate principle and equipment to distribution network? Then through analyzing the present situation of fault indicator gives the proposal of development direction which is about system itself function extension and acc-sess to the distribution automation system.
