Abstract:
The Doubly-Fed Induction Generators (DFIG) based Wind Turbines (WT) are widely used in WTs connected to power systems. Traditionally the back-to-back converters are used in order to control the DFIG. In this paper, an Indirect Matrix Converter (IMC) is utilized. Compared with back-to-back converters, IMCs have numerous advantages such as: higher level of robustness, reliability, reduced size and weight due to the absence of bulky electrolytic capacitor. According to the recent grid codes it is required that wind turbines remain connected to the grid during grid faults. It means that the plant must be in operation and be able to tolerate the fault conditions. This feature is called Fault Ride-Through (FRT) capability of wind plants. To improve FRT capability of the wind turbine, in this paper an adaptive gain scheduling controller is proposed. The proposed method could increase the damping of fault currents and hence attribute more time to controller for reactive power injection. Therefore, the new FRT standards are satisfied. PSIM simulation results confirm the efficiency of the proposed method.
