The limiting resistance in SFCL and the fault detection time impact on peak value of fault current, line voltage of feeders without fault and voltage across SFCL are analysed.
给出了超导限流器的数学模型,着重分析了超导限流器限流电阻和故障检测时间对短路电流峰值、非故障线电压、超导限流器上的电压的影响。
But under fault condition, the system current is greater than the current of equivalent AC current source and the limiting resistance take effect immediately.
故障后,系统电流值远大于等效交流电流源值,限流电阻立刻自动投入限流。
The estimating methods of the values of the discharge capacitor and limiting resistance in design of the constant current source are also given.
