Abstract:For the current large-scale wind farm, wind & fire bundled DC silos are used for delivery of transportation methods, but for no wind, fire, wind farm baling conditions, especially offshore wind farms, using wind, fire, transport bundling approach will greatly increase investment in wind power, or even feasible. Considering the advantages of thyristor rectifier device side and the inverter side commutation failure-prone fault, combined with full-controlled IGBT characteristics, this paper proposes a control strategy of received multiterminal DC system transporting mixed by the wind. The strategy uses the conventional DC rectifier device, and the inverter side uses VSC device, according to the two characteristics, the paper gives the topology and control flow chart and proposes master-slave control strategy. This strategy not only makes full use of the traditional rectifier device capacity, but also adopts the controllable characteristics of VSC, so as to realize the fluctuation of wind power delivered to the load center. A simulation model is built by using the actual size of the data of a wind farm, and the simulation results are analyzed. Simulation results verify the validity of the strategy.
