摘　　要：将电流注入模型引入交流等值法求解交直流电力系统潮流的过程,既保留了传统牛顿型等值法的收敛性,同时又减少了每次迭代的计算量。考虑到换流变压器实际变比的离散性,提出了一种一次性调整分接头的方法,提高了功率因数,减小了系统网损。算例验证了文中方法的有效性。By using a current-injecting model, the AC equivalent approach for AC/DC power system load flow calculation reserves the convergence characteristic of traditional AC equivalent method based on Newton model and reduces computation time per iteration. Taking the discreteness of the converter transformer ratio into account, this paper presents a method of one-time tap determination, which improves power factor, and reduces the loss of system. Numerical examples demonstrate the effectiveness of the proposed method.
