Control of Grid Side Inverter in a B2B Configuration for WT Applications

Studenteropgave: Speciale (inkl. HD afgangsprojekt)

  • Alin Raducu
The increase interest in renewable energy production together with higher and higher demand from the energy distribution companies (TSO) regarding grid energy injection and grid support in case of a failure raises new challenges in terms of control for wind turbine (WT) systems. Due to the above mentioned, grid side inverter control in WT systems is one of the main issues in decentralized power production units. This project deals with the design and implementation of one control method for the grid side converter in a back-to-back configuration. This project will review different control techniques for grid inverters systems and an overview of the grid codes will be included. Targeted applications are decentralized grid connected systems, wind turbines in this case, but motor/generator applications may also be considered. A particular control method has been selected and implemented in laboratory using a dSpace setup. The control strategy chose is Voltage Oriented Control (VOC) where the active and reactive power are regulated by controlling the id and iq current components.
