abstract
2016 IEEE. This paper describes a reference algorithm specifically designed for PMU Calibration System. Contrary to existing DFT-based and curve fitting-based methods, which use a single signal model, the proposed algorithm applies an adaptive mechanism, and switches signal models according to specific signal input. Signals are modeled with parameters with apparent and certain physical meaning, fundamentally avoiding error magnification from derivative calculation for frequency and rate of change of frequency estimation. Levenberg-Marquardt algorithm is used for solving the signal parameters. The test results show that the proposed algorithm has a much higher accuracy than the requirements of IEEE standard C37.118.1, and hence can serve as a reference algorithm in a PMU Calibration System.
