Oil and gas field energy saving control technology, with flexible start and stop, automatic impulse regulation, wireless level monitoring, automatic power regulation, downhole pump working condition analysis and diagnosis, direct drive and semi-direct drive control and other functions, realize the intelligent control of mechanical production equipment.
Example: The energy saving control system of the pumping unit realizes the soft start of the motor, which has no impact on the power grid. The power factor of the motor can be increased from 0.25 ~ 0.50 to more than 0.90, thus reducing the burden of the power grid and transformer, and reducing the line loss. It is easy to operate and can dynamically adjust the pumping rate according to the actual pumping capacity of the well without stopping production. By using the newly developed power of the motor which is adjusted in real time according to the change of load and equipped with the reverse power feedback device to transform the existing pumping unit, the oil well can save electricity, increase efficiency and increase production, so as to improve the mechanical recovery efficiency of the whole rod pumping system.
