Study and Control of Direct Driven Type-4 Grid Connected Wind Energy Conversion System

The main aim of this research is to develop efficient and reliable control strategies for a direct drive PMSG based variable speed wind turbines topologies which ensure an efficient and reliable grid integration of off-shore/onshore wind farm under normal and abnormal conditions. The main objectives of his work to develop a mathematical modeling and analysis of permanent magnet synchronous generator based variable speed wind energy system. Build a control strategy for maximum power point tracking algorithm for generator side converter and another control strategy for optimum utilization of grid side inverter rating under non-linear load and ensure unity power factor operation. The Simulation model and its control have been implemented in MATLAB SimPower System software.
