Space Vector Modulation Controlled Hybrid Active Power Filter for
Power Conditioning
Abstract:
In this project, presents a control method for hybrid active power filter using Space
Vector Pulse Width Modulation (SVPWM). In the proposed control method, the Active Power
Filter (APF) reference voltage vector is generated instead of the reference current, and the
desired APF output voltage is generated by SVPWM. Proper controller is developed to maintain
power quality with APF.
Passive filters have several drawbacks, which may cause harmonic interaction with the
utility problems with the utility system, in the presence of stiff utility sharp tuning of the LC
filter is required and may not meet the specified harmonic current limits. Now we have great
challenge is to investigation of an active filter topology, which is practically viable, cost effective
and can meet the recommended standard for high power nonlinear loads.
So, in this project, a new controller is proposed to maintain good power quality. The
proposed system is a control methodology for the APF using SVPWM. This method requires few
sensors, simple in algorithm and able to compensate harmonics and unbalanced loads. In the
proposed method generating APF reference voltage vector instead of reference current, and
generating desired APF output voltage by Space Vector Pulse Width Modulation (SVPWM)
based on generated reference voltage. Therefore, the proposed method is simple and easy to
carry out.
