要約(日本語): HVDC grids have gained interest for integrating large amounts of renewable energy such as offshore wind power generation. This paper focuses on a three-terminal bipolar HVDC grid and proposes a partial reconfiguration method that realizes the continuous operation of offshore wind power plants against the dc fault. The proposed method realizes reconfiguration by combining MMCs and low-voltage dc circuit breakers without high-speed and high-current interruption capabilities. The method has the potential to improve the supply reliability while avoiding the increase in costs due to the use of high-performance dc circuit breakers. Computer simulations demonstrate that the wind power plant can continue to operate against the dc fault.
