The fault diagnosis problem of active network is studied in this paper with the emphasis upon its solvability and diagnosability.

摘要本文研究有源网络的故障诊断问题，著重研究其可解性与可诊断性。

Moreover, the proposed control system is of some fault diagnosis and protection functions, such as overcurrent, overvoltage-undervoltage, overtemperature and parameter overrun.

同时，该电源控制系统还具有过流、过欠压、过热、参数超限等故障诊断与保护功能。

Based on this, the veracity of the rotor fault diagnosis can be improved through the distance of the information entropy curve chart at the multispeed.

实例计算表明，信息熵距能够较好的区分故障类别，在此基础上，通过多转速下的熵距曲线图可以提高转子故障诊断的准确性。
