摘　　要：考虑到在交流高压电网中,输电线路的电抗要比电阻大得多,线路两端的电压相角差很小的具体特点,本文提出一种利用直角坐标牛顿法进行简化的P-Q分解法。新的P-Q分解法的迭代过程中各元素不再需要重新计算,从而可大大提高潮流的计算速度,减少潮流计算的时间。仿真实验表明本文所提出的方法的有效性。Considering that in the AC-high voltage power grid, transmission-line reactance is much larger than the resistance, the specific characteristics of small voltage phase angle difference at both ends of the transmission lineo A simplified P-Q decomposition method is proposed through rectangular coordinate Newton method. Each element Each element is no longer need to recalculate in the iterative process of new P-Q decomposition method, which can greatly improve the calculation speed of flow, and further reduce the calculation time. The simulation experiment shows the effectiveness of the method proposed in this paper.
