Abstract
With the popularization of power electronic equipment, the harmonic problem of power system is more and more serious, which affects the power quality and system stability. This study focuses on harmonic analysis and governance, deeply studies its generation and propagation mechanisms, and provides theoretical and technical support for harmonic governance. Through the combination of theory and experiment, the Fourier transform and other tools are used to model the harmonic, and the data are obtained through simulation and test to analyze the law of the harmonic change. It is found that the nonlinear load is the main source of the harmonic wave, and the harmonic suppression method based on the adaptive filtering algorithm is proposed, which can compensate the harmonic current in real time and reduce the harmonic content. At the same time, the harmonic monitoring and evaluation system has been developed to realize the comprehensive monitoring. This study innovatively applies the adaptive filter algorithm to the harmonic governance, and constructs the harmonic monitoring system, which provides a new idea for improving the power quality.
