A New Wind Turbine Interface to MVDC Grid with High Frequency Isolation and Input Current Shaping Conference Paper uri icon

abstract

  • 2014 IEEE. This work introduces a new approach using high frequency (HF) isolation for interfacing next-generation offshore wind turbine generators (WTGs) to medium voltage DC (MVDC) collection grids, a necessity for the continued development of offshore wind resources as farms are sited further out to sea. Initial analysis of the proposed approach is provided, as well as a practical design example for reproduction of results and prototype design guidance for further development of the concept. Detailed simulation results demonstrate converter operation from full rated power down to 25% rated power. The WTG displacement power factor is found to be 0.95 leading. Simulation results further confirm near-sinusoidal WTG and transformer current, continuous output current, and stiff DC link voltage, all within specified ripple tolerances.
