Abstract:From the momentum models, numerical calculation and experimental research, the research methods of H-VAWT with variable pitch were introduced, and the advantages and disadvantages of various methods were presented. Focusing on the mechanical transmission pitching and hydraulic transmission pitching, the implementation scheme of VAWT with variable pitch was elaborated. It is pointed out that the small and medium VAWTs have difficulties in realizing the pitching law in the aspects including the overall response time, the real-time pitching in one cycle, the complex flow field in the downwind zone and reliable pitch control under dynamic stall. Finally, a moderate outlook for the future development trend of variable pitch VAWTs was given.
