摘要
针对原有测距系统故障点位置的检出与实际位置具有较大偏差的问题,提出基于PSCAD/EMTDC的风力发电场集电线路接地故障测距系统研究。构建故障测距系统框架,接收脉冲信号,设计非接触传感器分压单元,转换故障信号;基于PSCAD/EMTDC设定测距流程,获取故障点数据信息,通过最小分辨率给定测量间距,测量集电线路接地故障点发生距离。实验结果表明:以单极接地故障和双极接地故障作为测试类型,系统能够对不同距离接地故障点中的信号能量进行测量,保证故障点测距的精准度,减少测距误差,具有应用价值。
In order to solve the problem that there is a large deviation between the detected fault location and the actual location in the original fault location system,the research on the fault location system for grounding fault of wind farm collector line based on PSCAD/EMTDC is proposed.A fault location system framework is constructed,a pulse signal is received,a non-contact sensor voltage division unit is designed,and a fault signal is converted;a location process is set based on PSCAD/EMTDC,data information of a fault point is obtained,a measurement distance is given through minimum resolution,and the distance of a grounding fault point of a power collecting line is measured.The experimental results show that the system can measure the signal energy of different distance grounding fault points,ensure the accuracy of fault location,reduce the error of fault location,and has application value.
