In order to make MW power-level wind power generator use hydraulic drive to achieve the purpose of eliminating accelerator and converter to reduce cost and realize high-quality power generation on the ground synchronously,a technical scheme of ultra-low speed and super-large displacement hydraulic pump driven directly by wind wheel and transferring MW power level was put forward,and the parametric prototype model of the hydraulic pump was established based on ADAMS.The simulation analysis of scheme analysis,motion analysis,hydraulic cylinder design and flow characteristics was carried out.The results prove that the scheme of hydraulic pump is feasible,and the parameters can be further optimized and applied in practice.
