| Abstract: | 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. |
