为分析液压型风力发电机机组能量转化机理，针对其能量传递与耗散问题展开了研究。将整个机组分解为若干个关键子单元，建立机组能量传递模型，分析机组能量传递变化规律；以能量传递模型为基础，对机组能量耗散进行推导分析，得到机组能量耗散数学模型。将30 kV·A液压型风力发电机组实验台作为仿真和实验基础，对机组能量传递与耗散进行仿真与实验研究，进而验证理论分析的准确性。研究结果表明：机组在工作过程中其能量特征状态发生改变，并存在一定的能耗，整机效率约为65.7%。

Taking a hydraulic wind turbine as the research object,the energy transfer and dissipa-tion were studied for energy conversion mechanism in hydraulic wind turbine.The entire unit was di-vided into several key sub-units.The energy transfer models were established,and the variation of energy transfer was analyzed.The energy dissipation was derived and analyzed based on energy trans-fer models,and mathematical models of energy dissipation were obtained.Using 30kVA hydraulic wind turbine simulation platform as the simulation and experimental foundation,simulation and ex-perimental researches of energy transfer and dissipation were carried out.The accuracy of theoretical analyses was verified.The results show that energy feature state is changed during operation,contai-ning a certain energy dissipation,and the overall efficiency is about 65.7%.
