The invention discloses a virtual flux-based coordination control method for direction powder of a PWM rectifier, and belongs to the technical field of power electronics. The control method comprises the following steps: collecting three-phase power grid current and direct-current bus voltage, and calculating a virtual flux; calculating instantaneous power according to the power grid current and the virtual flux; adding load power, as whole feedforward and the direct-current bus capacitance power to obtain an active power reference value, and calculating an instantaneous power error; calculating reference voltage of the rectifier, and carrying out inverse coordinate transformation; and after amplitude limiting is carried out on the reference voltage of the rectifier, generating a driving signal of the PWM rectifier by virtue of a space vector modulation method. According to the coordination control method, the fluctuation of the direct-current bus voltage is effectively inhibited during load sudden change, and the operation efficiency of a system is improved; meanwhile, a power grid voltage sensor is omitted, so that the hardware cost of the control system is lowered, and the reliability of the system is improved; furthermore, a plurality of PI regulators are omitted in an inner power loop, so that the complexity of the system is reduced.
