含微网电源的智能配电网馈线故障自愈控制方法

Self Healing Control Method for Feeder Faults in Intelligent Distribution Networks with Microgrid Power Supply

常规智能配电网馈线故障自愈控制方法多数采用分层多代理原理设计而成。在实际应用过程中,馈线故障自愈控制时间较长,控制效率较低,影响电力系统正常运行。为解决这一问题,开展含微网电源的智能配电网馈线故障自愈控制方法的深入研究。在馈线故障发生后,快速定位馈线故障,准确找出馈线故障所在区间位置,并对馈线故障段区间进行隔离处理。在此基础上,对馈线故障进行自愈控制,恢复非故障区段供电。实验分析可知,提出自愈控制方法应用后,馈线故障自愈控制时间较短,均保持在3 s以内,能够在快速时间内实现故障自愈控制目标,可行性较高。

Most of the conventional self-healing control methods for feeder faults in intelligent distribution networks are designed using the principle of layered multi-agent.In practical applications,the self-healing control time for feeder faults is longer,the control efficiency is lower,and it affects the normal operation of the power system.To address this issue,in-depth research has been conducted on the self-healing control method for feeder faults in intelligent distribution networks with microgrid power sources.Firstly,after a feeder fault occurs,quickly locate the feeder fault,accurately locate the location of the fault section,and isolate the fault section of the feeder.On this basis,self-healing control is carried out for feeder faults to restore power supply to non fault sections.Experimental analysis shows that after the proposed self-healing control method is applied,the self-healing control time of feeder faults is relatively short,all of which are maintained within 3 seconds.It can achieve the goal of self-healing control of faults in a fast time and has high feasibility.
