摘　　要：介绍了离网式液压发电仿真系统及工作原理,对该系统进行了数学建模及Simulink仿真,并建立了系统的实验模型,通过改变液压马达的输入压力和流量的方式模拟了自然界的风能。结果表明:永磁发电机的效率在正常工况下是较高的,但整个系统的发电效率较低。The simulation system and working principle of the non-grid-connected hydraulic generation system were introduced. Then the mathematical modeling and Simulink simulation for the system were completed. The physical model of the system was estab-lished. Through the changes of the input pressure and flow rate of the hydraulic motor,the wind energy from nature could be simulated in this experiment. The results indicate that the efficiency of the permanent magnet generator under normal condition is higher,but the entire power generation system still has lower efficiency.
