The invention discloses special filtering energy feedback apparatus and a control method for a pumping unit. The special filtering energy feedback apparatus comprises a rectifying unit and a filtering energy feedback unit; the rectifying unit and the filtering energy feedback unit are connected with a direct current bus P+ and a direct current bus N- of the special filtering energy feedback apparatus for the pumping unit respectively; the direct current bus P+ and the direct current bus N- supply power to frequency converters of each pumping unit; a brake circuit of the pumping unit is connected with the direct current bus P+ and the direct current bus N- in parallel; and the filtering energy feedback unit feeds back the energy of the brake circuit of the pumping unit to a power grid side by adopting a PWM inversion manner. The special filtering energy feedback apparatus and the control method for the pumping unit have the beneficial effects that digital and intelligent feedback apparatus used for feeding brake regeneration energy of the frequency converter of the pumping unit; and the special filtering energy feedback apparatus also has the functions of active power filtering, reactive power compensation, three-phase imbalance correction and other electric energy quality managing functions, so that the purposes of environmental protection, energy conservation and consumption reduction are realized.
