| 摘 要： | 分析比较了故障分量比率差动保护和常规比率差动保护的基本原理，在不同故障情况下对两种差动保护的灵敏度做了比较，得出它们在不同故障情况下各自的优越性。利用MATLAB和SIMULINK构建一动态仿真模型，通过高阻接地故障试验，验证了故障分量差动保护的优越性。

| Abstract: | This paper analyses the basic principle of the differential protection of fault component ratio and the differential protection of normal ratio and compares the sensitivity of these two kinds of differential protection under the differential fault conditions,getting the result that each protection has its own advantages under the different fault conditions.The dynamic emulation model was established by use of MATLAB and SIMULINK and the advantages of the differential protection of fault component were verif... |
