Solution details

1. scope of application

 Efficient and energy-saving equipment.

2. Core technologies and processes

 A DC microgrid is formed through multi-energy complementary control such as wind/light/storage/grid power to supply power to multiple oil well electronic control terminals, giving full play to the advantages of DC power supply and multi-machine clusters. The flushing times of each pumping unit are optimized and adjusted according to the oil production conditions. Cluster coordination and monitoring management are realized through the Internet of Things, so that the feedback energy of each pumping unit is shared and recycled through the DC bus to improve energy efficiency, reduce harmonic pollution, and solve the problem of oil field pumping machine electronic oil production process and energy efficiency issues, which greatly reduce the capacity, number of transformers, line loss and power consumption of pumping units.

3. main technical parameters

 Working temperature: -40 - 80℃. Driving application range: three-phase asynchronous motors with rated voltages of 380V, 660V, and 1140V, permanent magnet synchronous motors, various pumping units with power range of 5- 55kW.

4. comprehensive benefits

 Compared with the traditional model, the number of transformers is saved by more than 90%, and the transformer capacity is saved by 65%. The active power saving rate of ton of liquid production is 15%-25%, and the reactive power saving rate is 90%-95%. The power factor on the grid side is better than 0.95.
