摘　　要：提出了一种电力系统不对称谐波 (基波 )潮流的分立迭代算法 ,该方法实现了基波潮流与谐波潮流的解耦。不对称基波潮流计算采用三相 P— Q分解法 ,而不对称谐波潮流计算则采用解线性三相节点方程的方法。通过对某一实际电网的计算表明 ,这种不对称谐波 (基波 )潮流计算方法计算速度快、占用内存少、收敛可靠 。This paper presents a separate iteration method for unsymmetrical harmonic power flow calculation. By thismethod, the fundamental power flow and harmonic power flow are decoupled. The unsymmetrical fundamental power flow iscalculated using 3--phase P-Q decoupling algorithm, while the unsymmetrical harmonic power flow is calculated by solving thelinear 3--phase node current equation. An example of an actual power system demonstrates that high-speed calculation. lessoccupied memory and reliable convergence can be obtained by the separate iteration method, and the proposed method may beused for harmonic power flow calculation of large power system.
