分析了信号注入法和暂态信号选线法各自的优缺点

提出了两者结合的组合选线方法。同时指出

在基于信号注入法选线装置的基础上进行改进

无需增加设备就可实现该组合方法。给出了算法流程图和硬件装置工作过程

同时对组合算法进行了仿真验证

仿真结果表明

该组合方法有较高的可靠性和准确性。

The superiorities and deficiencies of the fault line selection methods based on signal injection and transient signal are analyzed

then the combined method based on signal injection and transient signal is proposed.Simultaneously

the instrument based on the combined method could be realized by modifying the existing equipment based on the signal injection method

without additional equipments.The flowchart of the algorithm and the progress of the instruments were proposed

and the simulation of the combined method was carried out.The simulation results show that it has high accuracy and credibility.
