The invention provides a pumping unit direct current bus group control algorithm based on power weighted prediction. The pumping unit direct current bus group control algorithm based on power weighted prediction comprises the following steps: step 1, extracting, analyzing and storing operation data of a pumping unit click control inverter; 2, determining a real-time power spectrum of each oil pumping unit, giving a power weight, and calculating power weighting; step 3, calling a stroke frequency table of each pumping unit; step 4, establishing a well group prediction spectrum table; step 5, according to the prediction spectrum table, the frequency of the frequency converter is lowered in proportion; and 6, the set stroke frequency is reached after self-learning, and continuous operation is conducted according to the set stroke frequency. The pumping unit direct current bus group control algorithm based on power weighted prediction can effectively coordinate the operation states of all the pumping units, and t
