Analysis of loop power flow's transient process

In the analysis of loop power flow,the steady-state power floor that would cause the transmission lines or equipments overloaded is focused on and the transient process is ignored.Based on the analysis of the transient process in time domain,the mathematic expression of the loop power flow was established and discussed.The main factors that determined the loop power flow were found.The transient simulation of loop power floor was carried out.The simulation results verify the correctness of the result.
