ABSTRACT

A mainstream approach of eliminating the loop running is electromagnetic loop rejection to achieve the partitioning operation of power networks (Canizares et al. 1993). Because of the complexity of power system operation, multi-faceted calculation and analysis must be carried out before breaking up the electromagnetic loop, comprising power flow calculation, stability calculation, short-circuit current calculation, and network loss calculation. Moreover, other issues affecting the system operation should also be comprehensively considered to make reasonable and feasible decisions (Dong et al. 2009). Therefore, it has an important theoretical significance and application value to study the scheme of breaking up electromagnetic loop networks.
