1:对于所有等级的隶属度之和为1。 2：输出结果随某个变量的增大而qdh1的结果呈现出单调递增或递减 3:最后的等级出[0.2 0 0 0.8]这种情况是正常的，和可拓评判中的对于等级的距离的概念是不一样的。 只表现有变量是属于0.2这个等级的。

并用S函数编制相间距离保护和接地距离保护算法程序,构建相应的保护模块,实现了三段式距离保护。仿真结果表明,所建立的三段式距离保护模型能够正确反映在保护区内的不同类型的短路故障并发出动作信号,使断路器跳闸实现输电线路的保护功能。 (A distance protection simulation model of transmission line was established by using Simulink and SimPowerSystem toolbox inMatlab. S-function was used to programe the distance protection of phase faults and earth faults and the relevantprotectionmodelswere created to build distance protection.The simulation results show that the three-stage distance protectionmodel can respond to allkinds of faultswithin protection zones correctly and send correct signal to the breaker of the line. )
