抽油机柔性控制技术是以变频调速为基础,通过对油井载荷的分析和判断,实时调整电动机的转速、转矩和输出功率,实现电动机的主动变速运行,其充分利用系统惯性能,动态改变系统的运行轨迹,减小电动机功率的波动幅度,降低平均运行功率,可有效解决油井“大马拉小车”和“倒发电”的问题。经油田现场应用,综合节电率达到了19%,节能效果明显。 The flexible control technology of the pumping unit is based on the variable frequency speed regulation. Through the analysis and judgment of the oil well load, the speed, torque and output power of the motor are adjusted in real time to realize the active variable speed operation of the electric motor, which makes full use of the system inertial energy, dynamic Change the running track of the system, reduce the fluctuation range of the motor power, and reduce the average operating power, which can effectively solve the problems of the oil wells “Da Ma La Car ” and “Inverted Power ”. The oil field application, the comprehensive saving rate reached 19%, energy-saving effect is obvious.
