摘　　要：为了实现海流能发电的实际工况模拟,分析了直流电动机与水轮机的运行机理,探讨了二者的功率及转矩特性,设计了控制直流电机的电流转速双闭环控制策略,并利用Matlab/Simulink搭建了水轮机模拟仿真系统,完成了固定流速、缓慢增速和随机流速3种典型工况下的系统仿真实验。实验结果表明,电流转速双闭环的直流电动机控制系统可准确模拟水轮机的主轴转矩,适用于实验室条件下对海流能发电机的测试。In order to simulate the actual working condition of current energy generator, analyzes the operating principles of the DC motor and the hydraulic turbine, discusses their power and torque characteristics, and designs a double closed-loop control strategy for the control of current and speed of DC motor. Establishes simulation system of turbine by Matlab/Simulink and complete the system simulation tests under three typical working conditions of constant speed, slow growth rate and random flow rate. Experimental results show that the current and speed double closed-loop DC motor control system accurately simulates the main shaft torque of hydraulic turbine and meets the laboratory conditions for ocean current energy generator tests.
