摘　　要：由于环境位置、季节变化、装机容量、运行状态等因素,小水电并网运行时影响线路损耗。分析了小水电并网模型,得出相应的线路损耗变化量公式,探讨了小水电机组迟相运行对并网线路损耗的影响,并用PSASP进行仿真分析。Due to environmental location, seasonal changes, installed capacity, operating status and other factors, the operation of grid-connected small hydropower units affects the line loss. This paper mainly analyzes the grid-connected model of small hydropower and obtains the corresponding formula of line loss variation, discusses the influence of small hydropower units in lagging power factor operation on the grid-connected line loss, and conducts simulation analysis with PSASP.

关 键 词：小水电 线路损耗 迟相运行 PSASP
