| 摘 要： | 将SSSC安装于线路中点，根据SSSC在故障范围之内和之外2种情况，对阻抗继电器的测量阻抗进行了分析，且通过SSSC的不同注入电压和补偿方式，以及过渡电阻的变化，仿真了阻抗继电器的动作特性。结果表明，SSSC在故障范围之内时对阻抗继电器的测量阻抗产生了很大的影响，应该采取措施减小SSSC对阻抗继电器的影响；另外，过渡电阻的影响同样不可忽略。

| Abstract: | With SSSC installed at the mid-point of the line, the current study analyzed the measured resistance with SSSC present in and out the fault loop,respectively. The operation characteristics of the impedance relay was simulated depending on the different voltages injected, compensation modes and change of the fault resistance. The result shows the measured impedance is greatly influenced when SSSC is present in the fault loop, therefore measures should be taken to reduce the impacts of SSSC on the impedance relay. In addition, the influence of fault resistance on the measured resistance should be concerned. |
