针对海流发电机组转速控制问题，采用容积调速方法控制离网型海流发电液压传动机组的叶轮转速和发电机转速。设计了两种类似的海流发电液压传动系统方案，均采用泵-马达-发电机直接连接的结构形式。为验证所设计的液压传动系统方案的有效性，对其进行数学模型分析，并建立系统的MATLAB/Simulink模型进行系统控制特性仿真研究。结果表明，两种液压传动拓扑结构在满足最大功率跟踪控制要求的前提下，均可以在液压传动系统环节同时实现发电机恒频输出控制。

In light of the problem of speed control for the tidal current turbine,the volume control method is adopted to control the impeller speed and the generator speed of the stand-alone tidal current turbine.Two similar hydraulic transmission systems for the tidal current turbine are designed,both adopting the pump-motor-generator direct connecting structure.To validate the hydraulic transmission systems,the mathematical models for the systems are analyzed and the MATLAB/Simulink models are developed to study the working characteristics of the hydraulic transmission systems.The results show that both hydraulic transmission topologies can realize constant-frequency control of the generator on the premise of meeting the requirement of maximum power point tracking control.
