Matching of a wind turbine with a fan in underground spaces

Analyses characteristics of the wind turbine and ventilation fan for underground engineering, and discusses the matching scheme with a wind turbine as power supply. Verifies the scheme with calculation examples. The results show that the energy magnitude of the wind turbine can meet the demand of underground engineering ventilating when the matching wind speed reaches the design value. In the areas with wind abundant energy resources, this method can realize the effective wind energy utilization and promote the energy saving design of underground engineering ventilation.
