摘　　要：本文在具有可控电压的多智能体系统(MAS-CV)基础上,提出了带有PID控制器的无线传感器网络(WSN)自愈系统。由极变压器中的传感器完成误差检测,将感测到的数据传输到配电网,通过建立多智能体系统(MAS)受控功率输出分配给用户,以执行负载恢复过程,也就是分布式自愈过程。为了实现高效配电的目标,在此基础上引入了PID控制器,各个智能体可以通过有效的通信进行协调,以恢复停止服务的负载,所有负载恢复后,系统的压降由PID控制器控制。最后同时仿真验证了所提出的方法,结果表明该方法在短时间内为系统的修复提供了最佳解决方案,减少了开关次数,同时减小了配电成本。This paper proposes a self-healing system of wireless sensor network(WSN)with PID controller based on MAS-CV(Multi Agent System with Controllable Voltage).The sensor in the pole transformer completes the error detection,and transmits the sensed data to the distribution network.The distributed self-healing process is implemented by distributing the controlled power output to users through the establishment of a multi-agent system(MAS).In order to achieve the goal of efficient power distribution,a PID controller is introduced on this basis.Each agent can coordinate through effective communication to recover the load that stops service.After all loads are recovered,the system voltage drop is controlled by the PID controller.At the same time,the simulation results show that the proposed method provides the best solution for system repair in a short time,reduces the number of switching,and reduces the distribution cost.
