摘　　要：通过推导考虑分布参数效应的任意频率下的等效π模型参数和用于电磁暂态仿真的Bergeron模型参数,从理论上证明了只要已知输电线路的潮流数据,就能直接导出用于谐波分析的分布参数模型和用于电磁暂态仿真的Bergeron模型及Domm el模型,而与线路的真实长度无关,通过PSCAD程序对结论进行了验证。　Through deducing the equivalent π model parameter for orbitrary freguencies withe consideration of the distributed-parameter effect,and the Bergeron model parameter used for eletromagnetic trasient simulations,it is demonstrated that as long as the power flow data of the transmission line are given,the distributed-paramter line model used for harmonic analyses,the Bergeron model,and the Dommel model used for electromagnetic trasient simulations can be obtained directly withou having to know the actual length of the line.The conclusion is verified by PSCAD simulation.
