Abstract
This article delves into the relevant research on harmonic detection and control technology in the power grid. Firstly, the mechanism and characteristics of harmonic generation in the power grid were analyzed, and the impact of harmonics on the stability of power grid operation and equipment safety was pointed out. Furthermore, traditional harmonic detection methods were reviewed and their limitations in detection accuracy and real-time performance were pointed out. On this basis, this article introduces the development and application of modern harmonic detection technology, providing new ideas for accurate detection of power grid harmonics. This article studies the design and optimization methods, as well as control strategies, of passive filters, active power filters, and hybrid filtering devices for the treatment of power grid harmonics. By evaluating and improving the performance of these filtering devices, effective technical means have been provided for the control of harmonics in the power grid. Finally, this article proposes a harmonic control scheme based on multi-ob jective optimization, designs a distributed harmonic control system architecture, and explores the harmonic collaborative control strategy in the smart grid environment. The implementation of these plans and strategies will help improve the operational efficiency of the power grid, ensure the safe and stable operation of equipment, and reduce the negative impact of harmonics on the power grid. This study not only provides systematic theoretical support and technical guidance for the detection and control of harmonics in the power grid, but also offers new ideas and methods for the construction and development of smart grids.
