In addition to reactive-power management for power factor correction and voltage regulation, load balancing, and voltage flicker reduction, active power filters (APFs) also provide harmonic filtering, damping, isolation, and termination. APFs are now more economically feasible for commercial applications due to recent decreases in the cost of power semiconductor and signal processing devices. This study uses Synchronous Reference Frame Theory to suggest a new approach for obtaining the necessary reference current for the Voltage Source Converter (VSC) of a Shunt Active Power Filter (SAPF). The method achieves optimal control of the SAPF by utilizing the performance of a Proportional-Integral (PID) controller. The reference signals are transformed from the a-b-c stationary frame to the 0-d-q rotating frame by applying Reference Frame Transformation, desired reference signals for Pulse Width Modulation.

摘要

In addition to reactive-power management for power factor correction and voltage regulation, load balancing, and voltage flicker reduction, active power filters (APFs) also provide harmonic filtering, damping, isolation, and termination. APFs are now more economically feasible for commercial applications due to recent decreases in the cost of power semiconductor and signal processing devices. This study uses Synchronous Reference Frame Theory to suggest a new approach for obtaining the necessary reference current for the Voltage Source Converter (VSC) of a Shunt Active Power Filter (SAPF). The method achieves optimal control of the SAPF by utilizing the performance of a Proportional-Integral (PID) controller. The reference signals are transformed from the a-b-c stationary frame to the 0-d-q rotating frame by applying Reference Frame Transformation, desired reference signals for Pulse Width Modulation.
