摘　　要：750/330 kV电磁环网的存在不利于电网安全稳定经济运行。研究了甘肃中部750/330 kV电磁环网对甘肃电网的不利影响,通过供电平衡、潮流分布、短路电流等技术经济比较,提出了甘肃中部750/330 kV电磁环网的解环时机和方案。解环后的仿真计算表明,甘肃电网的各项运行指标得到了明显改善。750/330 kV electromagnetic loop network is harm for power system network operating safely, stably and economically. This paper studies the adverse effects of 750/330 kV electromagnetic loop network in central Gansu power network. With analysis and research such as power supply balance, power flow distribution and short -cir- cuit current level, the uncoupling time and scheme of 750/330 kV electromagnetic loop network in central Gansu power network is presented. The simulation result after the uncoupling 750/330 kV electromagnetic loop shows that the operation of Gansu power network is improved significantly.
