PROJECT TITLE :

Operating Modes and Control Strategy for Megawatt-Scale Hydro-Viscous Transmission-Based Continuously Variable Speed Wind Turbines

ABSTRACT:

A megawatt (MW)-scale hydro-viscous transmission-based continuously variable speed wind turbine is proposed to guarantee a sleek transition among completely different operating regions and hence to improve power efficiency and quality. This turbine is achieved by highly integrating a hydro-viscous element into the turbine drive-train to mitigate the upstream wind-loading fluctuations. This component permits the turbine speed to be directly regulated by continuously changing the oil film thickness in this component. 3 important operating modes of this turbine system are proposed. The management-oriented drive-train model is additionally established and validated primarily based on experimental information. A cooperative control strategy over the complete operating vary is then proposed based mostly on such modes. A series of comparative cosimulations are administered to guage the soundness and effectiveness of the proposed turbine system in speed and power regulations. This proposed system holds many advantages such as massive power capacity, high potency, downsized power converters, and low price. Such benefits build this turbine system notably enticing and promising for medium-to-large-scale wind power applications.
