摘要:
文章针对PQ 分解法在导线截面较小(r>x)的低压配电网络应用时存在不收敛的问题,根据B.Stott 模型在PQ分解法的基础上提出采用由程序自动进行支路截断的改进PQ 支路截断法,解决了r/x 比值较高的电缆网络及更高的某些三绕组变压器网络的收敛性问题。并分别利用PQ 法和改进的PQ 支路截断法对7 节点及11 节点电力网络进行了仿真分析,实验结果验证了本方法的正确性和可行性,并且减少了迭代次数,加快了潮流计算的迭代速度,更有利于实时准确监测电网参数。
Abstract:
An improved PQ branch decomposition method-the program automatically decomposes tributary was proposed in thepaper. It aimed to offset the deficiency of PQ method in low voltage distribution network with small cross-sectional area of conductor.Also B. Stott model was quoted to prove the applicability of the method in cable and some three-winding transformer network of larger/x value. Emulations between PQ and PQ branch decomposition in seven and eleven node network in order to test and verify the PQbranch decomposition method. According to the simulation results the later method was accurate and feasible also reducing iterations,accelerating the rate of flow calculation, measuring power network faster compared to PQ method.
