For the enormous potential of beam pumping unit’s energy saving, the frequency energy-saving control system of smart pumping unit with the function of self-learning has been developed on the basis of advanced technology and methods both in the domestic and abroad. The application of frequency converter not only has solved the impact problem at startup, but also improved the power factor significantly. For the solution to the shortage of oil wells, the system is to sample the parameters of Motor unit continuously under the conditions of relatively original and the conditions of normal working. The working liquid level as object to be controlled, the system is to adjust the liquid withdrawal rate to be sure the ability to match with the fluid through VVVF, and then a better energy-saving effect be obtained. The application of practical operation shows that the system can run efficiently and realize energy saving of the pumping.
