Abstract
his paper presents a method for obtaining the
desired reference current for Voltage Source Converter (VSC)
of the Shunt Active Power Filter (SAPF) using Synchronous
Reference Frame Theory. The method relies on the
performance of the Proportional-Integral (PI) controller for
obtaining the best control performance of the SAPF. To
improve the performance of the PI controller, the feedback
path to the integral term is introduced to compensate the
winding up phenomenon due to integrator. Using Reference
Frame Transformation, reference signals are transformed from
a − b − c stationery frame to 0 − d − q rotating frame.
Using the PI controller, the reference signals in the 0 − d − q
rotating frame are controlled to get the desired reference
signals for the Pulse Width Modulation. The synchronizer, the
Phase Locked Loop (PLL) with PI filter is used for
synchronization, with much emphasis on minimizing delays.
The system performance is examined with Shunt Active
Power Filter simulation model
