摘要
针对现有不迭代端口补偿法计算误差大、迭代端口补偿法计算工作量大的问题,提出计及并联支路影响的端口补偿改进算法.充分利用配电网辐射状的结构特点,采用基于相分量的端口补偿法计算配电网故障,既提高了计算速度又保证了计算精度.通过算例对所述方法进行测试,并与传统算法的计算结果进行了对比分析,证明了本算法的可行性、有效性和优越性.
In view of the large computational error of the existing non iterative port compensation method and the large computational load of the iterative port compensation method, an improved port compensation algorithm is proposed. To make full use of the radial structure of distribution network, the back/forward sweep method is used to solve the open voltage of the fault port, the new fault port impedance matrix is used simultaneously which consider the influence of parallel branches. It not only improves the calculation speed, but also ensures the calculation accuracy. The method is tested by an example and compared with the traditional algorithm. The feasibility, validity and superiority of the algorithm are proved.
