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。研究了甘青断面750/330 kV电磁环网对甘肃电网的不利影响,通过对短路电流、潮流分布、送电能力等技术经济比较,提出了甘青断面750/330 kV电磁环网的解环时机和方案。仿真计算表明,甘肃电网的各项运行指标得到了明显的改善。750/330 kV electromagnetic loop network is harmful to secure and economic operation of power system network. Study on the adverse effects of Gansu-Qinghai network partition 750/330 kV electromagnetic loop network in Gansu power grid. With analysis and research of short-circuit current level, power flow distribution and transmis- sion ability, the uncoupling time and scheme of 750/330 kV electromagnetic loop network between the Gansu-Qing- hal network partition were presented. The simulation result after the uncoupling 750/330 kV electromagnetic loop shows that each operation index of Gansu power system was improved significantly.
