Based on a new approach of active harmonic compensation in power system and the filter adaptive control principle, an intelligent active filter system with the core part DSP-TMS320F2812 is proposed. By using this control system, the grid datas are collected, tested, processed and calculated. As the calculation results, high harmonic parameters are achieved and converted to the control signals. Then these control signals are sent to IPM driver circuits and used to control active filter to compensate for all the harmonics in the grid. As a result, the effectiveness of power quality is improved. Furthermore, the monitoring data from the grid and filter can be real-time displayed in the LCD. The simulation and actual experimental results of this system show that it has good effectiveness on power quality compensation.
