摘　　要：针对五民线无高抗运行的典型情况，利用EMTP程序对发电机自励磁和五民线的工频过电压、潜供电流、操作过电压等问题进行了详细计算和分析，指出了五民线无高抗运行应注意的问题，并提出了限制措施。Concerning the typical operating situation that the Wu-min line is not equiped with shunt reactor, the questions such as generators'self-excitation,power frequency overvoltage,secondary arc current,switching overvoltage,were calculated and analyzed with the use of EMTP program.Some questions,which should be paid attention to under the operationg situation of the Wu-min line without shunt reactor,and some limited methods are pointed out.
