Abstract

Reliability of power supply is related, among other factors, to the control and protection devices allocation in feeders of distribution systems. In this way, optimized allocation of sectionalizing switches and protection devices in strategic points of distribution circuits, improves the quality of power supply and the system reliability indices. In this work, it is presented a mixed integer nonlinear programming (MINLP) model, with real and binary variables, for the sectionalizing switches and protection devices allocation problem, in strategic sectors, aimed at improving reliability indices, increasing the utilities billing and fulfilling exigencies of regulatory agencies for the power supply. Optimized allocation of protection devices and switches for restoration, allows that those faulted sectors of the system can be isolated and repaired, re-managing loads of the analyzed feeder into the set of neighbor feeders. Proposed solution technique is a genetic algorithm (GA) developed exploiting the physical characteristics of the problem. Results obtained through simulations for a real-life circuit, are presented.

为提高配电系统可靠性指标，优化配置分闸和控制保护装置

除其他因素外，供电的可靠性与配电系统馈线中控制和保护装置的配置有关。这样，在配电线路的战略点上优化配置分闸和保护装置，提高了供电质量和系统可靠性指标。本文提出了一种具有实数变量和二值变量的混合整数非线性规划(MINLP)模型，用于战略区域的分段开关和保护装置分配问题，旨在提高可靠性指标，增加公用事业账单和满足监管机构对电力供应的需求。优化的恢复保护装置和开关的分配，允许系统的故障部分可以被隔离和修复，重新管理分析馈线的负载到邻近馈线的集合。所提出的求解技术是利用问题的物理特性开发的遗传算法。给出了实际电路的仿真结果。
