摘要：

为研究储能飞轮对游梁式抽油机性能的影响及节能效果，从理论上推导了影响电动机输出功率的数学模型，并建立了飞轮储能游梁式抽油机的虚拟样机模型，采用ADAMS进行仿真分析验证了模型的可行性，并探讨了不同传动比和转动惯量对游梁式抽油机性能的影响。结果表明：抽油机工作在上冲程时飞轮释放能量，在下冲程时飞轮吸收能量；游梁式抽油机中安装储能飞轮可有效降低电机启动扭矩，并减小电机扭矩、功率和速度的波动幅值；随着储能飞轮转动惯量的增大各项参数的波动幅值均有所减小，但一定程度上延长了电机的启动时间；通过计算电机功耗发现，在不同飞轮转动惯量下，飞轮还可以抑制倒发电现象，且随着转动惯量增大电机平均功率减小，使游梁式抽油机节能效果更为明显。

Abstract:

In this study, a mathematical model affecting the output power of the motor is theoretically deduced and a virtual prototype of a flywheel energy storage pumping unit is developed to investigate the influence of an energy storage flywheel on the performance of a beam pumping unit and the energy-saving effects. The feasibility of the proposed model is verified via ADAMS simulation analysis, and the effects of different transmission ratios and moments of inertia on the performance of the beam pumping units are discussed. Results show that the flywheel releases energy when the pumping unit works in the upstroke mode and absorbs energy when the pumping unit works in the downstroke mode. Therefore, the installation of an energy storage flywheel in a beam pumping unit could effectively reduce the initial torque of the motor and reduce the fluctuation amplitude with respect to the motor torque, power, and speed. The fluctuation amplitude of each parameter decreases with the increasing rotational inertia of the energy storage flywhee; however, the starting time of the motor will be prolonged to a certain extent. Based on the power consumption of the motor, the flywheel is observed to inhibit reverse power generation under different rotational inertias. Furthermore, the average power consumed by the motor will decrease with the increasing rotational inertia, improving the energy-saving effect of the beam pumping unit.
