This paper analyzes the changes of active power flow on the communication channel between regional power grids, summarizes the influencing factors affecting the active power flow, and provides a theoretical basis for the analysis of the combined loop conditions of the electromagnetic loop network between regional power grids. From the perspective of the power angle characteristics of the power system, the relationship between the active power and the power angle of the power supply of the two power networks is derived. The influence of the power angle change on the active power flow in the communication channel between the regional power grids is theoretically analyzed. The correctness of the derivation conclusion is verified by ETAP simulation modeling. Finally, the 35kV grid in Shou County, Huainan, is taken as an example to analyze the influence of power angle on the active power of the loop. The research results show that the change of power angle on the communication channel between regional power grids has a direct impact on the change of active power flow, and the power angle can be used as an important criterion for the electromagnetic ring network.
