Study on Short-term Energy Storage Characteristics of Hydraulic Wind Turbines at Micro-scale Turbulent Wind Speed

研究微尺度湍流风速对风力机输出功率的影响，在均速为额定风速的微尺度湍流风速作用下，分析蓄能器有效容积、单位质量储能和充电状态等主要参数与湍流部分的关系。并在此基础上，提出一种既能短期储能又能使发电机处于额定功率运行的液压风力发电系统。并就微尺度湍流强度为12%额定风速情况，对带有蓄能器短期储能的10 kw液压风力发电系统进行仿真研究，结果表明，带蓄能器短期储能的液压风力发电系统比没有蓄能器的液压风力发电系统输出能量提高11.3%。
In this paper, the impact of micro-scale turbulence wind speed on wind power generation is studied. The relationship between some key parameters such as the accumulator effective volume, unit mass storage, state of charge and turbulence parts is analyzed when the mean of the micro-scale turbulence wind speed is the rated wind speed. Based on that, a hydrostatic wind power generation system and its corresponding control method are proposed, which can not only realize the short-term storage energy, but also keep a wind turbine working at the rated power. Finally, for the 10 kw hydrostatic wind power generation system with an accumulator implementing short-term storage energy, the simulation analysis is carried out when the micro-scale turbulence intensity is 12% of the rated wind speed. The simulation results show that the output energy of the hydrostatic wind power generation system with a short-term storage accumulator is 11.3% larger than that of the corresponding system without accumulator
