The system comprises a power quality multi-functional detection system, a power quality power standard source, a high-precision time synchronization source and a calibration host computer.The system is simple in structure and can realize a protocol test, monitoring analysis and field comparison multi-service full-automatic calibration on a power quality monitoring device, and investment on manpower and material resources is reduced. Meanwhile, the method provided by the invention can realize automatic reading of a protocol model, test data, a time code and an IRIG-B signal from thepower quality multifunctional detection system, calculate an error and automatically output a calibration result to a calibration report, so that calibration efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of calibration of a power quality monitoring device, in particular to a multi-service calibration system and a calibration method for a power quality monitoring device. Background technique [0002] At present, there are many power quality monitoring devices newly connected to the network every year. There are relatively mature solutions for the accuracy detection of power quality monitoring devices. The direct method is used, that is, the standard source is used to send corresponding signals to realize the accuracy detection of power quality monitoring devices. The on-site comparison of the power quality monitoring device can perform online calibration on the power quality monitoring device installed in the substation. The on-site comparison requires that the accuracy of the standard power quality monitoring device is higher than that of the tested power quality monitoring device, and the results are require...

AI Technical Summary

Problems solved by technology

At present, there is no corresponding test method that can manually test the above-mentioned functions one by one in the laboratory for multiple services such as protocol testing, monitoring analysis, and on-site comparison of power quality monitoring devices. It is time-consuming, laborious and inefficient, and the detection error cannot be achieved. Therefore, there is an urgent need to develop a calibration system for multi-services such as protocol testing, monitoring analysis, and on-site comparison of power quality monitoring devices to improve work efficiency and achieve multiple automatic calibrations of protocol, accuracy, and timing
