| 摘 要： | 10 kV线路合环转供电可提高供电的延续性,但由于线路的负荷、合环开关两侧存在电压差、相角差等原因,合环时产生的环流容易导致操作失败。在仿真软件计算的基础上,结合实际的操作经验,总结出中山电网10 kV线路合环转供电的操作原则,对降低合环操作的电网风险和提高供电可靠性具有重要意义。

| Abstract: | Switching the power supply in a closed loop of 10 kV lines can improve the continuity of power supply.However,the operation may fail due to the ring current arising in the closed loop,as a result of the difference of voltages and phases between the two sides of the closed-loop switches and loads.Based on the calculation of simulation software and practical operating experiences,the operating principles of switching the power supply in a closed loop of 10 kV lines in Zhongshan Power Grid are summarized,which plays an important role in reducing the grid risk during closed-loop operation and improving the reliability of power supply. |
