Research on the Control Strategy of the Inter-provincial Electromagnetic Loop Network in Hubei Power Grid

摘要

Hubei-Henan transmission section is the first 1000kV/500kV/220kV three-level electromagnetic loop network in China and the most complex loop network in Hubei. According to the present situation of Hubei-Henan transmission section and Hubei-Hunan transmission section electromagnetic loop, the characteristics of the electromagnetic loop network between provinces and the problems that it brings to the security and stability of Hubei grid are analyzed. With the network structure characteristic of Hubei Grid considered, the exiting problems are studied and the corresponding control strategies are proposed. This work can provide certain practical value for the operation of the inter-provincial transmission sections in Hubei grid.
