The invention discloses a power distribution control system applied to a hydraulic system. The power distribution control system comprises a controller, a pressure sensor, a displacement sensor, a rotating speed sensor, a handle, a proportional electromagnetic valve and an executing mechanism. The controller is used for collecting and processing signals, carrying out related operation processing and sending out a control instruction; the pressure sensor is used for measuring oil pump outlet pressure and determining load conditions; the displacement sensor is used for detecting the displacement of the oil pump variable servo oil cylinder so as to determine the actual displacement of the oil pump; the rotating speed sensor is used for measuring the rotating speed of the motor, determining the running speed and feeding back to the controller for closed-loop control; a swing angle signal of the handle is transmitted to the controller in a current form, and the controller controls the current of the proportional electromagnetic valve of the oil pump through logical operation; the proportional electromagnetic valve controls the displacement of the oil pump, and electromagnetic valve control current and the displacement of the oil pump are in a linear relation. According to the invention, the power of the engine can be fully utilized, and the work efficiency of the system can be ensured.
