全时检验关口计量在线监测与远程故障诊断系统

介绍了一种关口电能计量装置在线监测与远程故障诊断系统,采用GPS同步采样和低压电力线宽带载波通信同步技术,实时采集关口电能表和电压、电流互感器二次回路信号,实现关口计量装置全时检验和运行状态监测。通过计量设备异常事件数据库实现对异常事件的判别、记录、告警,通过故障仿真平台还原现场故障电压、电流波形,实现关口电能表在异常工况下的误差检验,应用智能化专家诊断和状态评估技术,实现关口计量装置的可靠性、剩余寿命的判断。

The All - time Inspection Online Monitoring and Remote Fault Diagnosis System for Gateway Meters

This paper introduces a complete online monitoring and remote fault diagnosis system for electricity meters at gateways.The all-time state monitoring of the metering device is realized by collecting the signals of electricity meters at gateways, CT and PT secondary circuits in real time.The functions of distinguishing, recording and warning of abnormal events are realized by the abnormal event library.The voltage and current waveforms generated by various faults can be reproduced on the fault simulation platform in the laboratory to realize remote error testing.The system can comprehensively improve the level of operation and maintenance management of metering devices at gateways and ensure the safe and stable operation of metering equipment.
