摘要：在进行合环潮流分析时，一般只考虑合环后的稳态量是否引起系统中线路或设备过载，而忽略了合环操作的暂态过程。为了解决这一问题，在对合环潮流中环流分量的暂态过程进行时域分析的基础上，推导了合环网络中环流的数学表达式，并对各环流分量进行了详细讨论，得出了合环潮流大小的主要影响因素。最后用PSS/E对合环过程进行了暂态仿真，暂态仿真实验验证了分析结果的正确性。

Abstract: 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.
Key words: loop power flow; transient analysis; loop flow component; initial phase; transient simulation
