Abstract
The control strategy and design of an AC/DC/AC IGBT‐PMW power converter for PMSG‐based variable‐speed wind energy conversion systems (VSWECS) operation in grid/load‐connected mode are presented. VSWECS consists of a PMSG connected to a AC‐DC IGBT‐based PWM rectifier and a DC/AC IGBT‐based PWM inverter with LCL filter. In VSWECS, AC/DC/AC power converter is employed to convert the variable frequency variable speed generator output to the fixed frequency fixed voltage grid. The DC/AC power conversion has been managed out using adaptive neurofuzzy controlled inverter located at the output of controlled AC/DC IGBT‐based PWM rectifier. In this study, the dynamic performance and power quality of the proposed power converter connected to the grid/load by output LCL filter is focused on. Dynamic modeling and control of the VSWECS with the proposed power converter is performed by using MATLAB/Simulink. Simulation results show that the output voltage, power, and frequency of VSWECS reach to desirable operation values in a very short time. In addition, when PMSG based VSWECS works continuously with the 4.5 kHz switching frequency, the THD rate of voltage in the load terminal is 0.00672%.
