摘　　要：配电网中辐射线路的最优分段处理是一个需要同时考虑经济性和可靠性的非线性组合优化 问题。采用结合了遗传算法的全局搜索特性和禁忌搜索算法的局部搜索特性的混合算法来求解该 问题,所采用模型的目标函数同时考虑了分段开关的年投资与维护费用以及将可靠性效益转化为 经济性指标的用户缺电成本。最后采用一个简单算例验证了文中方法的可行性,并在实际系统中 得到了应用。Optimal sectioned switches placements of radial lines in distribution network systems are a combined optimization problem with non-linear objective, which should satisfy both economy and reliability indexes. A hybrid algorithm based on global searching trait of genetic algorithm and local searching trait of tabu search algorithm is presented to find the global optimal solution. The function of the model in this paper combines annual investment and maintenance costs of sectioned switches and customer outage cost which transforms reliability benefit to economy index in order to arrive at an optimum decision. Finally, the algorithm described in this paper is testified by a simple example, and is suitable to be used in actual distribution systems.
