山西中部电网弱电磁环网高压通道开环检修方式适应性问题研究

Study on the Adaptability of Open-loop Inspection and Repair Method for High-voltage Passage of Weak Electromagnetic Loop in Central Power Grid of Shanxi Province

针对山西中部电网云龙线停电检修方式带来的220kV送电通道不满足N-1运行要求的问题进行了研究,提出了合理的解环措施调整策略。实际运行证明,调整后的运行方式有效地解决了相关过载问题,且满足短路电流运行要求,适应性较好,对解决类似电磁环网打开问题,具有一定参考意义。

Aiming at the problem that 220 kV transmission channel in central Shanxi power does not meet the requirements of-1 principle with the outage of Yunlong line,a reasonable adjustment strategy is proposed.The actual operation proves that the adjusted operation mode effectively solves the problem of power flow overload,and can meet the operation requirements of short-circuit current.The conclusion is helpful for solving the similar problems of electromagnetic ring opening.
