Abstract

This paper presents a comparative study on the most popular control strategies used to control high power, Direct Drive Wind Turbines. For the generator-side converter, performances of the Field Oriented Control (FOC) and Direct Torque Control (DTC) are compared. Concerning the grid-side converter, Voltage Oriented Control (VOC) and Direct Power Control (DPC) are examined. The comparison is based on various criteria including, implementation complexity, steady-state and transient performances. The simulation and evaluation of control strategies are performed based on a supervision scheme developed for a 2MW Direct Drive wind turbine. In addition, performances are evaluated in terms of accordance with Grid Connection Requirements (GCR) including, low voltage ride through capabilities (LVRT), power limitation and reactive power control.
