摘要
针对采用故障指示器实现配电网故障区段定位时,现有算法求解不可靠,提出一种元胞混合蛙跳算法。对经典混合蛙跳算法引入元胞自动机搜索原理以增加算法多样性,提升算法的局部搜索能力,加强求解的效率;并建立复杂配电网故障定位数学模型,验证该算法对于配电网发生单点、多点故障并出现部分畸变信息情况下的求解可行性;最后对比经典混合蛙跳算法,数据表明该算法在局部收敛、寻优能力和求解准确率上具有优势,可以实现高效、准确的故障区段定位。
In view of the unreliable solution of the existing algorithm when fault indicator is used to locate the fault section in distribution network, this paper proposes a cellular shuffled frog leaping algorithm. The shuffled frog leaping algorithm is introduced with cellular automaton search to increase the diversity, enhance the local search ability of the algorithm and the efficiency of solving. Moreover, a mathematical model of fault location for complex distribution network is established to verify the efficiency of the algorithm in the case of single-point and multi-point faults and partial distortion information in distribution network. Finally, compared with the classical shuffled frog leaping algorithm, the data show that the algorithm has advantages in local convergence, searching ability and solving accuracy. This algorithm can achieve efficient and accurate fault location.
