Title:Control and Detecting Method for
Active Power Filter
[Abstract] Recently, energy efficiency is greatly increased due
to the application of many power electronic equipments in electric power system. However, the harmonic pollution caused by those facilities has catched people’s attention. In these facilities used to reduce harmonic pollution, active power filter (APF) will e the focus in the future study because of its favorable dynamic response pensating characteristics..
In this dissertation, first, the APF’s concept, principle and development are separately described in detail, and a practicality real-time precision harmonic current detecting method is presented, which is based on the instantaneous reactive power theory and the balance of power and no need to putation. Secondly, the control loop of APF is optimized and a variable structure control model is adopted, so the dynamic response of power ci
