Memory, power grid frequency adjusting method, system, equipment and device

The invention discloses a memory, and a power grid frequency adjusting method, system, equipment and apparatus. The method comprises the steps of obtaining a current power grid frequency in real time and calculating a frequency deviation value between the current power grid frequency and a reference power grid frequency; generating rotation speed correction of the pumping unit motor according to the frequency deviation; generating a current input given value of a current control link according to the rotation speed correction and the current rotation speed of the pumping unit motor; generating a frequency adjusting signal of the inverter according to the current input given value and the current current feedback value of the pumping unit motor; wherein the frequency adjusting signal is used for adjusting the rotating speed of the pumping unit motor. According to the invention, the frequency of the power grid within the jurisdiction range of each transformer in the power grid of an oil field enterprise is take
