Performance Analysis of boost chopper - Current controlled inverter on PMSG Based Wind Energy conversion Systems

Abstract

Now days in many high performance applications of Voltage source PWM inverters,current control is an important part of the overall control system. In this paper, a new current-control method is proposed for the grid side inverters employed with the PMSG based WEC systems. The main purpose of this proposed method is to provide a pure sinusoidal current to the grid, even in the existence of nonlinear and unbalanced loads. The inverter receives the DC input from the Boost converter .The purpose of connecting boost converter in WEC System and its the mathematical model are clearly presented .To show the improvement in working performance this novel method is compared with the Current hysteresis control ,voltage oriented method . The proposed method is simulated using Matlab Simulink. The Simulation result shows the improved performance of this new inverter current control scheme.
