| 摘 要： | 蚁群算法是一种求解组合最优化问题的新型通用启发式方法,该方法具有正反馈、分布式计算和富于建设性的贪婪启发式搜索的特点。通过建立适当的数学模型,基于故障过电流的配电网故障定位变为一种非线性全局寻优问题。该文将蚁群算法用于配电网故障定位方面的研究,并通过实例证明了该算法的可行性和高效性。

| Abstract: | Ant colony algorithm is a new general-purpose heuristic algorithm for combinatorial optimization problems. The main characteristics of this method are positive feedback, distributed computation and the use of constructive greedy heuristic. By building an appropriate model, the fault location in power distribution network based on the fault overcurrents is transformed into a nonlinear global optimization problem. This paper presents a new algorithm based on ant colony search algorithm to solve the fault location in power distribution network. Numerical examples demonstrate the feasibility effectiveness of the proposed method. |
