The invention relates to the technical field of operation machine control, and provides an operation machine control method and device and an operation machine, the operation machine comprises a power dragging system, a capacitance system and at least one driving system, and the method comprises the steps that the power grid voltage and the residual electric quantity of the capacitance system in the working process of the operation machine are monitored in real time; under the condition that the power grid voltage is overvoltage and the residual electric quantity is smaller than a first electric quantity threshold value, a power dragging system is controlled to supply power to a driving system and charge a capacitor system at the same time; and under the conditions that the power grid voltage is under-voltage, the residual electric quantity is greater than a second electric quantity threshold value, and the residual electric quantity enables the current voltage of the capacitance system to meet an under-voltage difference value, controlling the capacitance system and the power dragging system to jointly supply power to the driving system. According to the invention, when the voltage of the power grid is unstable, the capacitor system plays a role in stabilizing the voltage of the power dragging system through charging or discharging, so that the power dragging system can stably supply power to the driving system, and the operation efficiency is not affected.
