针对游梁式抽油机平衡装置效果不理想的问题,设计了风光储联合供电的抽油机自动平衡装置;该装置由伺服电机驱动平衡块,根据油井工况实时调节其位置,实现抽油机的最佳平衡;针对平衡装置耗电量大的不足,设计了由风光储联合供电的模式,真正实现抽油机节能;最后,对该装置设计了模糊PD自适应控制器,由模糊控制器在线调节PD控制器参数;在实验室试验10h,该装置可将抽油机平衡度从1.61减小到1.03以内,白天由太阳能电池供电,夜间由蓄电池供电,其电压从12V降到9.3V,表明供电系统完全能满足要求。

英文摘要：

Aiming at the problem of the bad effect of the balanced device for beam pumping units, the auto balanced device powered by wind--solar--battery is designed. In this device, the counterweight is actuated by servo motor according to the condition of the oil well, which realizes the best balance effect. Considering the disadvantage of energy consumption of the device, the power is supplied by the wind-- solar--battery energy, which makes the beam pump unit realize energy saving truly. Finally, the fuzzy PD controller is designed for the de- vice. The experiment in laboratory takes ten hours. The device can decrease the balance index from 1.61 to 1.03. The power is supplied by the solar battery in the daytime and by the storage battery at night. The output voltage is from 12V to 9.3V at night, which shows the power supplement system can satisfy the needs of the device.
