| description | A motor microgrid system for an oil pumping unit comprises a double-winding oil pumping unit motor, the voltage levels of two sets of windings can be adjusted, and matching is carried out according to the voltage of a wind-solar complementary power generation system. A first winding of the double-winding oil pumping unit motor is electrically connected with an inverter serving as a motor controller, and a second winding of the double-winding oil pumping unit motor is electrically connected with a power frequency power grid through a contactor. And the power frequency power grid is also electrically connected with an inverter serving as a motor controller so as to send the phase sequence signal to the inverter serving as the motor controller. The problems that in the application process of a pumping unit system, new energy is complex in system and limited in reliability are mainly solved. By providing a new microgrid structure based on double windings, the reliability, adaptability and cost performance of wind |
