摘要：

为提高海流发电组的能量捕获效率并提高输出稳定性，对液压容积控制实现海流发电系统的变速恒频进行研究.在海流发电液压传动系统中采用变量液压泵和液压变压器，通过变量液压泵的排量调节和利用液压变压器的变压作用来分别实现叶轮转速控制和发电机转速控制.为验证该液压传动控制系统的有效性，完成了小型海流发电液压传动系统数学模型分析，并建立海流发电液压传动系统Matlab/Simulink模型进行系统控制特性仿真研究.结果表明，采用液压容积控制和液压变压器的液压传动拓朴结构在满足最大功率跟踪控制要求的前提下，可以在液压传动系统环节同时实现发电机恒频输出控制.
Abstract:

In order to improve the tidal current turbine's power efficiency and its power output stability, a control method realizing variable speed constant frequency through adjusting the hydraulic displacement was researched. A volume adjustable hydraulic pump and a hydraulic transformer were used in the tidal current turbine hydraulic transmission system. The turbine speed control and the generator speed control could be realized separately by adjusting the displacement of the volume adjustable hydraulic pump and the transformation of the hydraulic transformer. For validating the hydraulic transmission system, the mathematics model of a small tidal current turbine prototype was analyzed and a Matlab/Simulink model of the tidal current turbine hydraulic transmission system was built to study the control performances of the hydraulic transmission system. The results show that the hydraulic transmission method using the hydraulic displacement control and the hydraulic transformer can realize the constant frequency control of the generator under the premise of meeting the maximum power point tracking control.
