The induction motor used by pumping unit of oil field has a great potential for energy saving under the condition of the periodic load operation. This paper researched energy-saving of the intermittent power supply control method, and put forward the rapid soft re-switching technology to solve the impact of current and the corresponding loss with the re-switching, the validity of this method is proved by the simulation. Redrawing the total loss of induction motor under variable running condition and get the optimal voltage curve. The paper combines intermittent power supply control and optimal regulating-voltage, it can get better energy-saving effect through analysis and comparison of several energy-saving ways.
