Pitch Controlled PMSG Based Wind Energy Conversion System with Control of DC Link Voltage and Load Voltage Variations
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 6
Abstract
In this paper, a novel algorithm, based on dc link voltage, is proposed for a standalone permanent magnet synchronous generator (PMSG)-based variable speed wind energy conversion system. Moreover, by maintaining the dc link voltage at its reference value, the output ac voltage of the inverter can be kept constant irrespective of variations in the wind speed and load. An effective control technique for the inverter, based on the pulse width modulation (PWM) scheme, has been developed to make the line voltages at the point of common coupling (PCC) balanced when the load is unbalanced. Pitch angle control of wind turbine under higher wind speed also implemented with the reference of generator speed. Based on extensive simulation results using MATLAB/SIMULINK, it has been established that the performance of the controllers both in transient as well as in steady state is quite satisfactory and it can also maintain maximum power point tracking.
