基于直流母线的抽油机井群控系统技术的探讨

Discussion on Group Control System Technology of Pumping Unit Based on DC Bus

抽油机的传统配电方式采用“一井一变”模式,一定要满足功率最大值且留有很大余量,效率低、浪费大。为了改善这一问题,开展基于直流母线的抽油机井群控系统的研究与应用,充分挖掘抽油机直流互馈群控技术在节能方面的优势,通过逆变器实现多台电动机的能量回馈,完全吸收、回馈利用负发电,节约能源,对于提高油田的生产管理水平以及生产过程中的能源利用程度,具有重大意义。

The traditional distribution mode of pumping unit adopts"one well and one change"mode,which must meet the maximum power and leave a large margin,low efficiency and large waste.To improve this problem,in rod-pumped well group control system based on dc bus in the research and application of pumping unit was fully dc feed each group control technology in energy-saving advantages,through the inverter to realize motor energy feedback,more complete absorption and availability of negatively charged,save energy and to improve the level of oil field production management and production process of energy utilization degree,is of great significance.
