| 摘 要： | 蚁群算法在配电网故障区段定位中应用效果良好,但具有搜索时间长、计算速度慢等缺点,为此对蚁群算法进行了改进。首先构造了动态适应配电网拓扑结构的开关函数,其次提出了蚁群信息素初值设置方法,引入解的扰动规则,最后确定了蚁群算法应用于多电源条件下配电网故障区段定位的方法。算例结果验证了该算法在计算速度和容错性方面的优势。

| Abstract: | Although good application effect of locating faulty section in complex distribution network can be attained by applying ant colony algorithm,however there are also disadvantages such as too long search time and computation time.For this reason,traditional ant colony algorithm should be improved.Firstly,a switching function that can dynamically adapt to topological structure of distribution network is constructed;then a method to set the initial values of ant colony's pheromone and the disturbance rule of th... |
