摘　　要：在电源电网一体优化模型中 ,将输电网络规划到 2 2 0 k V电压等级 ,电源和负荷点与实际地理位置相对应。该模型从经济角度将电源电网规划有机结合 ,用最小费用增益网络流算法优化电力网络 ,并利用系统装机容量逐台扩展的方式 ,克服了电源电网一体优化的计算复杂性。同时 ,考虑了输电线直流潮流约束。经实例演算 。In the generalized sources and networks optimum model, the voltage of the transmission networks is planned out 220kV. The source and load points corresponds to their real positions. The sources are combined with the networks planning organically from the economic point of view. The networks are optimized by using the minimum cost gain networks flow method. The difficulties of the generalized sources and networks optimization calculation are surmounted by expanding the capacity of the generating sets in the systems one by one .The D.C. power flow restrains are considered. The results are satisfactory by the actual calculations.
