| Abstract: | The backbone of power grid is made up of 500 kV transmission lines. For ensuring grid operating safely, it is important to improve communication quality and reliability of 500 kV optic fiber protection channel. The paper introduces backbone power communication network in Zhejiang, discusses main protection configuration for 500 kV power line based on the characteristics of current differential protection in each phase. It is proved that the configuration will influence the quality of protection channel directly. |
