本文介绍了在实验室环境下，利用潮汐轮机仿真器对脉动转矩减缓控制策略进行建模和评估。潮流速度的突然变化和可变性对潮流涡轮机产生脉动的影响。这些脉动对潮汐涡轮机的疲劳和极限载荷以及动力传动系统的运行都有不利影响。基于上述原因，本文提出并试验了一种基于修改发电机参考最大功率点转速的脉动转矩减缓控制策略。本文介绍了在实验室设置评估这种脉动力矩减缓控制策略。在MATLAB/Simulink中对一台7kw潮流水轮机进行了建模。利用转矩控制的感应电机，在实验室装置中对潮汐涡轮机进行了仿真。结果表明，该方法在实验室环境下的有效性，发电机根据速度控制器命令进行加速和减速的能力，以及脉动转矩减缓控制策略与最大功率点操作（MPPO）的区别。此外，还将实验结果与Simulink模型进行了比较，验证了建模过程的准确性。
This article presents the modelling and assessment of a pulsating torque mitigation control strategy by using a tidal turbine emulator in a laboratory environment. Sudden changes and variability of the tidal flow velocity have the effect of creating pulsations on tidal current turbines. These pulsations have an adverse effect on tidal turbine fatigue and ultimate loading as well as the operation of the drivetrain. For the above reasons, a pulsating torque mitigation control strategy has been developed and tested which is based on modifying the reference maximum power point speed of the generator. This article presents the assessment of this pulsating torque mitigation control strategy in a laboratory setup. A 7 kW tidal current turbine is modelled in MATLAB/Simulink. The tidal turbine is emulated in the laboratory setup by using a torque‐controlled induction motor. Results show the effectiveness of the method in a laboratory environment, the ability of the generator to accelerate and decelerate based on the speed controller commands and the difference between the pulsating torque mitigation control strategy and maximum power point operation (MPPO). In addition, the experimental results are compared with a Simulink model which will show the accuracy of the modelling process.
