Design of Active Power Filter Based on DSP
Along with the access of nonlinear load and the development of electric power system, the harmonic pollution in power system is deteriorating. Harmonic not only affects the reliability, safety and economic operation of power system but also poses potential risks to power users. An active power filter with TMS320F2812 DSP as the core is designed for harmonic compensation for power system in this paper. With the hardware circuit configuring, software programming and circuit debugging, the system performances and parameters are tested and studied during normal operation respectively. The testing results show that the designed hardware circuit and software program are correct. The designed filter has the advantages of simple circuit structure and good compensation effect.
