Study on Pumping Units with Wind Power Generation Complementary Power Supply System
The wind power generation pumping unit has environmental protection and the energy-saving function with wind power generation complementary power supply system. Based on the calculation of the pumping power consumption during the oil production, the essential wind-power generation electric quantity for pumping equipment runs stable was analyzed, wind-electricity and electric network complementary energy transmission and control circuit were designed, When the wind speed changes, by the energy transmission and control circuit related parameters and taking the historical meteorological statistics of the corresponding period as the comparison reference, the system can control wind power generation and the battery charge and discharge flexibly to ensure the equipment runs stable, which lays a firm foundation for the wide application of the off-grid wind power. The economic analysis shows that the wind-electricity and electric network complementary pumping machine has good economic efficiency and application prospect in oilfield.
