- Description
- Voltage and current harmonics can have various deleterious effects on the entire power system, from residential households to power utilities. The onus to correct these harmonic problems lies dually with the end user and the power utilities. Active Harmonic Filters are one solution that can ensure the supply of clean power, to end users in a distributed system. Research into active harmonic filters has become an area of growing interest in the recent years. This is due to the increased use of non-linear loads, coupled with greater demand for electricity in general. This paper outlines the development of simulations and low voltage modeling of a pure active harmonic filter. The filter is composed of a three phase inverter direct-connected in shunt with the load and a microcontroller used to implement the control strategy. The control algorithm and filtering are performed in the dq rotating reference frame. This implementation attempts to improve the control scheme proposed by Akagi et. al for “Pure Active Harmonic Filters.” The output stages of the control scheme are replaced with a predictive current controller with space vector modulation. Simulation and experimental results are provided to support the findings of this paper.
