To compensate harmonics from nonlinear load, the controller of Active Power Filter (APF) need to detect harmonic and generate compensation current in high speed. APF controller functions are divided into two parts: outside controller part and inside controller part. Inside controller part detect harmonic current and control the IGBT to generate grid harmonics current. Outside controller part detect common power parameters and generate signal of management in main circuit. An experiment circuit of APF Controller is established. Some experiments are presented here.

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.

Evaluation of the Shunt Active Power Filter apparent power ratio using particle swarm optimizationThe main objective of this present paper is the study of the Shunt Active Power Filter (APF) compensations capability for different perturbations in AC power system such as current unbalance, phase shift current and undesired harmonics generated by nonlinear load and/or by the power system voltage. This capability is determined by the maximum rate of the apparent power that can be delivered. This study is based on the definition of the effective apparent power as defined in IEEE 1459-2000 which was proved to be the suitable amount to be concerned in the design process of different devices.

Non-linear loads generate harmonic current in power system. These harmonics currents can produce various type of effect that is harmful to the power system. A system required to filter out these harmonics. Design and assessment of shunt active power filter (SAPF) for harmonics elimination using intelligent control controller (fuzzy logic) present in this paper. Generally, conventional phase-locked loop (PLL) technique are used for eliminate harmonics. In PLL technique based system contains more harmonic. This paper compared without filter versus with filter at different loads. Results shows that intelligent control controller based system contain minimum harmonic contain as compared to conventional controller

With the wide application of power electronic equipments in power system, more and more harmonic are poured into the power system, which cause power pollution and make the power quality problem increasingly serious. Active power filter (APF) is an important equipment to compensate harmonic and reactive current in power system. One of the key technologies lies in the real-time and accurate control. The fundamental principles of several control strategies of compensate current were presented, and the respective merit and demerit of these control strategies were pointed out with contrast analysis in this paper. Active power filter will achieve a higher performance and a wider application with the continuous development of the control strategy.
