【摘要】：针对分布式电源接入配电系统后使得原有的故障定位原理难以满足故障检测要求的问题,本文采用Petri网原理,根据配电系统的网络结构,利用故障发生时系统检测到的故障信息,建立了含分布式电源配电网的故障定位模型,阐述了推理过程,通过对故障信息的预处理,保证当故障信息丢失时故障定位的准确性。为验证该方法的故障定位能力,利用Matlab中Petri网工具箱,对一个含分布式电源的复杂配电网进行仿真分析。仿真结果表明,在配电系统发生单一或多重故障时,该配电网故障定位模型都能得到正确的故障区段;同时当故障信息缺失时,仍可取得理想的定位效果。因此,该故障定位模型具有一定的实际应用价值。
[Abstract]:For the distributed power access to distribution system makes the original principle of fault location is difficult to meet the problem of fault detection requirements, this paper adopts Petri network principle, according to the network structure of distribution system, fault information using fault detection system to the established fault location model with distributed power distribution network, expounds the reasoning process. The pretreatment of fault information, ensure the accuracy when the fault information is lost. The fault location for fault location capability verification of the method, using Petri toolbox in Matlab, the simulation analysis of a complex distribution network with distributed power. The simulation results show that the distribution system in single or multiple faults, the distribution network fault location model can obtain the fault section correctly; at the same time when the fault information is missing, can achieve the ideal positioning effect. Therefore, the fault set The bit model has some practical application value.
