摘要
现阶段,低压配电网在运行中存在低压故障点定位困难、配电变压器非电量信息监测率低及故障频发、电缆终端头非接触式测温不准确、缺乏对多源数据及不同通信网络具有良好兼容性的数据平台等问题,极大地影响了配电网络运行的安全性和可靠性。针对该问题,利用电力物联网技术,研制了配电设备智能诊断分析系统并进行了应用。该系统能够及时预警低压故障并确定故障位置,有效监测配电变压器运行参数,并能实现电缆终端头的接触式测温。研究成果有效提升了配电网的精益化运维水平,对于提高供电可靠性及优化营商环境具有十分重要的促进作用。
At current stage,during the operation of the low-voltage distribution network,there exist various problems,such as low-voltage fault point positioning difficulty,low monitoring rate of non-electricity information of distribution transformers,frequent failures,inaccurate temperature measurement of cable terminal heads,shortage of the data platform with good compatibility to multi-source data and different communication networks,which greatly affect the operation security and reliability of the distribution network.To solve these problems,an intelligent diagnostic analysis system for power distribution equipment was developed and applied by using power Internet of Things technology.The system can timely warn low-voltage faults and determine the fault location,effectively monitor the distribution transformer operating parameters,and can achieve contact temperature measurement of the cable terminal.The results of the project have effectively improved the lean operation and maintenance level of the distribution network,which is very important to promote the reliability of power supply and optimize the business environment.
