The present disclosure provides a power control method for a vertical pumping unit. A whole stroke of the vertical pumping unit is divided into four running stroke sections of upper-range upward, upper-range downward, lower-range downward and lower-range upward. Every time when a motor control system receives a neutral position signal, at least one upward or downward motor running parameter is converted according to a specified stroke setting of an upper half range or a lower half range, and reversing is implemented after running according to at least one specified stroke parameter is completed or one of an upper position signal and an lower position signal is triggered. When another neutral position signal is received again, the motor control system automatically performs zero position calibration.
