Abstract :
This paper presents a performance analysis of wind-powered self-excited induction generator (SEIG) and a vector-controlled PWM converter. Three-phase voltage-source converters are the building blocks of a large number of power electronic systems. The origin of difficulties in the control of the above converters is in their nonlinear nature. The PWM current control technique is used to derive the switching signals for the converter. Closed-loop control of the converter utilizes a conventional proportional integral (PI) controller. In order to examine the dynamic performance of the system, its model is simulated and results are analyzed. The simulation results and experimental results are presented. The experimental results were obtained using Dspace DS1104 R&D controller board which confirms good performance of the proposed control system and agree with the simulation results. The results verify the validity of the proposed model and show practical promise in renewable energy applications.
