Design and Implementation of On-Site Calibration Device for Intelligent Power Transmitter Based on ARM+FPGA

Intelligent power transmitters provide important functions such as data acquisition, monitoring and control for power systems. Affected by factors such as the on-site environment, device aging, and uncertainty of wind power and photovoltaic output, power transmitters may have problems such as reduced measurement accuracy and difficulty in calibration. An on-site calibration device for intelligent power transmitter is designed and implemented based on ARM+FPGA, and its key hardware and calibration system software are discussed in detail in the paper. The test results show that the calibration device can meet the calibration and long-term stability requirements. This study provided an effective way for on-site calibration of power transmitters.
