A PLC-Based Fuzzy Control System for ESP

Abstract:

With the oilfield development entering into high water cut stage, ESP (Electric Submersible Pump) was widely used with its strong oil recovery capacity. At present, there is a big gap in ESP control technology between ours and overseas, the traditional line frequency control failures frequently, has low system efficiency, serious energy waste and high operation cost, and frequency conversion control can't real-time automatic adjustment. According to these existing problems, fuzzy control was introduced into ESP system control, a fuzzy control algorithm was put forward by this paper, then fuzzy controller was realize by using PLC programming. This control system not only reserved the flexible, reliable and strong ability to adapt characteristics of PLC control system, and improved the of intelligence level of the system. Ensure esp real-time efficient and reasonable operation, prolong operation life, and enhanced. With this control system, ESP can real -time run efficiently, prolong the operating life, enhance the system efficiency, save energy and reduce consumption
