基于D-PMU量测信息的有源配电网故障诊断方法OA北大核心CSCDCSTPCD
Fault Diagnosis Method for Active Power Distribution Network Based on D-PMU Measurement Information
社会经济的发展对快速找出故障源并采取相应措施提出了更高的要求.首先提出了一种基于D-PMU信息和Petri网的有源配电网故障诊断方法,基于多点D-PMU的高频全采样和配合故障信息数据,提取所分析时刻的故障特征向量,并通过可疑故障元件库和故障诊断模型,采用Petri网技术进行故障诊断,获得故障状态.然后考虑实际电网中保护动作具体形式和整定配合原则,给出了基于有源配电网的故障特征获取元件故障模型以及拒动、误动的判定规则的方法,所提方法能够应用于有源配…查看全部>>
The development of society and economy has put forward higher requirements for finding out fault sources quickly and taking the corresponding measures. In the paper,a fault diagnosis method for active power distribution net-work based on distributed phasor measurement unit(D-PMU)information and Petri net is proposed,which extracts the fault characteristic vector at the time of analysis on the basis of high-frequency full sampling data of multi-point D-PMUs a…查看全部>>
