An intelligent control for three-phase and four-wire active power filter
نویسنده
چکیده
Abstract. The paper presents a compensating system for the harmonics and the reactive power using active power filter in three-phase and four-wire systems. The conventional active power filters have been designed based on the p-q theory. However, these types of the filter can only compensate for the reactive power for the load and the detection result is not accurate if the three-phase voltage is distorted. To overcome this deficiency, a novel ip-iq algorithm based on the p-q theory is proposed for the control strategy of the active filter. The obtained simulation results show that by using the proposed control strategy, the total harmonics distortion in Matlab/ Simulink can be minimized.

A Hybrid Control Method for Stable Operation of Active Power Filters in Three-Phase Four-Wire Networks
The main goal of this study is the use of Lyapunov’s stability theory to a three-phase four-wire shunt active power filter (SAPF), since this method has been applied effectively to other areas of converter. The dynamic model of the SAPF is first established, after that, a combination of fuzzy tracking control and Lyapunov function is suggested in order to impose a desired transient waveform on ...
