Firstly,the scheme to uncouple500kV/220kV electromagnetic loop network in Harbin-Jiamusi and Harbin-Mudanjiang City sections is presented,based on the analysis on the500kV/220kV electromagnetic loop network in the middle and eastern section of Heilongjiang.Moreover,the influence of uncoupling electromagnetic loop on short-circuit current of500kV substation is analyzed.Finally,security and stability analysis calculations in middle and eastern grids are carried out after uncoupling electromagnetic loop,which enables the power network safely and stably operate.
