基于PSO算法构建环状母线电网故障自愈系统
摘要：为了提高电网故障自愈系统所产生的社会效益，对电网故障自愈系统中存在的各个因素进行了详细分析，并提出了影响电网故障自愈系统的社会效益系数。通过将自愈负荷量、分断开关操作代价以及社会效益综合，构建电网故障自愈系统的目标函数，利用多目标PSO算法对目标函数进行了分析和评估，并在环状母线的基础上对电网故障自愈系统目标函数进行了验证，最终得出本文提出的电网故障自愈系统目标函数具有较强的收敛性，社会效益得到大幅提高。

Construction of Self-healing System for Ring-bus Power Grid Based on PSO Algorithm
Abstract: In order to improve the social benefits produced by the power grid self-healing system, the factors existing in the power grid self-healing system are analyzed in detail, and the social benefit coefficient affecting the power grid self-healing system is proposed. The objective function of power grid self-healing system is constructed by combining self-healing load, operation cost of breaking switch and social benefits. The multi-objective PSO algorithm is used to analyze and evaluate the objective function, and the objective function of the power grid self-healing system is verified on the basis of the ring-bus. Finally, it is concluded that the objective function of the power grid self-healing system proposed in this paper has strong convergence, and the social benefits are greatly improved.
