For the sake of real-time online monitoring the operating state and parameters of electric energy metering devices, detecting the abnormal states of devices, predicting the trend of electric energy metering device error, and changing the traditional management mode for electric energy metering devices, which adopts the cycle test rotation mechanism, this paper has proposed a state management system of electric energy metering device based on NI CompactRIO platform. The proposed system can implement real-time online management for monitoring the measurement error of electric energy meter, data acquisition of electric energy meter, test of Secondary Voltage Drop and Secondary Load of PT, test of Secondary Load of CT, video monitoring, measurement of temperature humidity, measurement of space magnetic, etc. The system combines CompactRIO platform and electric energy metering devices to acquire, monitor and analyze the real-time online data corresponding to electric energy meter, CT, PT and secondary loop. And the Energy metering error and the evaluation of parameters of electric energy metering device are calculated by the CPU, and the data is exchanged with the remote station by communication network. So the system improves the management efficiency and benefits of electric energy metering devices.

Electric Energy Meter

The verification of electronic type electric energy meter is under strict reference conditions, but some special operating conditions at locale will exceed the standard scopes. In order to improve the calculation accuracy and operating reliability of electric energy meter under operating conditions, it is necessary to study the operating conditions. According to the working principle and the standard verification regulation of electronic type electric energy meter, this paper summarizes these operating conditions: low power factor, harmonic waves, dynamic impulsive load, voltage fluctuation and outside magnetic field of power frequency, then analyzes the causes of operating conditions and their influence on electronic type electric energy meter, eventually lays foundation for thorough and systematic study of electric energy meter in the operating conditions, and establishes measurement center database of operating conditions.
