| 摘 要： | 利用PSCAD对典型500k V同塔双回输电线路建模,通过FAULT模块设置短路故障仿真模拟出了潜供电流和恢复电压波形,从而为重合闸设备的重合时间和相关的继电保护定值相关参数设置提供了依据,并为有效的熄灭线路因静电耦合和电磁耦合产生的二次电弧提供了重要参数。同时深入分析了500k V同塔双回输电线路电抗补偿、短路点位置和土壤电阻率对潜供电流和恢复电压的影响,对500k V同塔双回输变电工程的调试、启动和运行具有一定的指导意义。

| Abstract: | This paper used the electromagnetic transient simulation software PSCAD, setting up the typical 500 kV modeling with double circuit transmission line tower. Through the FAULT element in PSCAD setting relatedSparameter, simulate theSSecondary Arc Current and Recovery VoltageSof endSline in short circuit fault, which provides a basis for theScorrelationSparameter to set toSreclosing timeSandSrelay protection setting of reclosingSdevice. And further analysis the effect of reactance compensation,Sfault location andSsoil resistivity to the 500kV Double CircuitSLine. The Model of 500 kV system has significant significance of design, safe and reliable operation of double circuit transmission line tower. |
