| 摘要: |
| 分析了分布式电源（DER）的短路电流特征和DER准入容量限制。通过分析有源配电网非故障区段与故障区段两侧开关短路电流的幅值关系，提出利用流过线路区段两侧的短路电流幅值比较进行有源配电网故障定位。MATLAB／ Simulink仿真结果表明，该方法在DER准入容量满足公共连接点处的电压变化量要求的情况下，可以实现有源配电网故障定位。 |

| Abstract: |
| The short circuit current properties of DER （Distributed Energy Resource） and its allowed capacity are analyzed. The relationship of short circuit current amplitude between faulty and healthy zones is analyzed and it is proposed to locate the fault of active distribution network by the comparison of short circuit current amplitude between both sides of a feeder section. The simulative results by MATLAB／Simulink show that，the proposed method can locate the fault when the allowed capacity of DER satisfies the voltage offset of point of common coupling. |
