摘要：

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30kV·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%。

Abstract:

Taking a hydraulic wind turbine as the research object, the energy transfer and dissipation were studied for energy conversion mechanism in hydraulic wind turbine. The entire unit was divided 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 transfer models, and mathematical models of energy dissipation were obtained. Using 30kVA hydraulic wind turbine simulation platform as the simulation and experimental foundation, simulation and experimental 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, containing a certain energy dissipation, and the overall efficiency is about 65.7%.

Key words: wind power, hydraulic transmission, energy transfer, energy dissipation
