摘要
从软仿真角度对配电自动化仿真系统的算法进行分析,提出对模拟的配网线路进行基于结点(支路)分层法的配电网络拓扑分层,常规潮流算法可采用前推回代法,短路电流计算可采用基于节点阻抗矩阵、关联矩阵短路故障算法.并对算法进行了叙述,对比了仿真软件与ETAP、Matlab算例结果,证明了仿真软件数据的准确性.
This paper examines the algorithm of distribution automation simulation system from perspective of soft simulation, proposing that point (branch) topology stratification can be used for simulation of distribution network and that the back/forward sweep method can be employed for conventional flow power algorithm and algorithm for calculating shortcircuit fault based on node impedance matrix and correlation matrix can be used for calculating short-circuit current. A presentation as to the algorithm is provided comparing the results of simulation software, ETAP and Matlab. The results show that the simulation software is accruate.
