A new method of calibration signal implementation in power quality monitoring devices based on heterogeneous equivalence of similarity theory is proposed in the paper. Timing-shift similarity calculation between the sampling signal sequence of the monitoring device and the output signal sequence of standard source has been carried out so as to analyze calibration signal synchronization method and its composition. Output method of heterogeneous calibration signal has been considered in the case of the whole point sampling and random sampling of the monitoring device. In addition, the calibration software about power quality monitoring devices is developed to measure the accuracy of the devices. Calibration results show that the questions of asynchronous between the sampling signal of the monitoring device and the output signal of standard source, and mutual interference between adjacent calibration signals are completely solved, which will greatly improve the accuracy and reliability of detecting the monitoring device, as well as the level of monitoring grid and user power quality. Moreover, it will play a positive role in upgrading and promoting the technology and industrial development of power quality monitoring devices.
