The power quality problem is one of the core problems encountered by the current distribution network, so more and more power quality management equipment has been widely used. Faced with the complexity of the current power grid, it is of great significance to analyze the adaptability of active power quality management equipment under different grid intensities. Aiming at the development and application of new technologies under the background of “carbon peak and carbon neutrality” in China, this article starts with grid adaptability and considers four typical scenarios of voltage deviation, frequency deviation, three-phase imbalance, and voltage harmonics, and focuses on equipment The four performance indicators of loss, harmonic emission level, compensation performance and response time are used to analyze the power grid adaptability of the equipment; based on the simulation software, the power grid adaptability analysis of the equipment compensation performance is carried out. Finally, take a certain LCL-APF filter on the market as an example to conduct a grid adaptability test, and it is concluded that as the strength of the power grid decreases, the grid adaptability of the equipment shows an upward trend.
