Optimal Design of Passive Harmonic Filter with High Power Factor

Nowadays, power electronic devices and other nonlinear loads are widely used in low-voltage power distribution system (LVPDS), which will produce a large number of harmonics, reduce the quality of voltage and current, and may also affect the normal operation of other equipments. Passive harmonic filter (PHF) is a main method to suppress harmonics in LVPDS. However, especially under the condition of high power factor, how to give consideration to both harmonic suppression and reactive power compensation must make a compromise between several contradictory objectives. For the above reason, this paper proposes a optimization design method of PHF bank based on improved particle swarm optimization algorithm for LVPDS with high power factor, in order to improve the overall performance of PHF bank. Finally, a design example of PHF bank of LVPDS in a beverage production company is given to illustrate the superiority and feasibility of the proposed method, which has a certain value of popularization and application.
