Abstract
A control method and a control device applied to an electric fracturing apparatus are provided. The electric fracturing apparatus includes a plunger pump and a first motor configured to drive the plunger pump, and the method includes: acquiring a preset displacement of the plunger pump; acquiring a rotation speed of the first motor and a discharge pressure of the plunger pump; determining a real-time displacement of the plunger pump based on the rotation speed of the first motor and the discharge pressure of the plunger pump and adjusting the real-time displacement; and upon the real-time displacement reaching the preset displacement, allowing the first motor to be kept in a stable operation state.
