Purpose. The article aims to improve the control methods for multifunctional parallel active filters (PAFs) to ensure rapid and precise compensation of inactive full-power components in three- and four-wire mixed power systems, particularly for group power supply systems for drives with capacitive energy storage devices. Methods. The paper proposes two methods for PAF control: the instantaneous power method (p-q theory) and the control method in a synchronously rotating coordinate system based on the Park-Gorev transformations. Simulations were conducted to compare the performance of PAFs using these control methods. The article evaluates the effectiveness of these control methods in compensating inactive power components and minimizing reactive power in group power supply systems. Results. The study found that controlling PAFs in a synchronously rotating x-y coordinate system simplifies the selection and control of inactive power components, leading to faster and more accurate compensation. Including zero sequence current in the compensation, reference currents allow PAFs to function in both three- and four-wire systems without additional zero sequence current compensation devices. Simulation results demonstrated the PAF’s effectiveness in compensating reactive power, harmonics (5th, 7th, and 49th), and inactive power components in diode rectifiers and in load symmetry correction. Originality. The study introduces an improved control method for multifunctional PAFs, particularly within group power supply systems using capacitive energy storage. This approach provides a novel way to address energy savings and improve power quality in systems with nonlinear and dynamic loads, reducing energy losses and improving equipment lifespan. Practicality. The results offer practical solutions for enhancing the efficiency of power supply systems in industrial settings. Using PAFs with capacitive energy storage reduces energy exchange between motors and the grid, mitigating losses in transformers, converters, and supply lines. Implementing this method improves energy management, enhances equipment longevity, and ensures compliance with power quality standards.
