Electronic speed regulator for diesel generator set

The utility model discloses an electronic speed regulator for a diesel generator set, which comprises a sampling unit, a control unit and a feedback unit, wherein the sampling unit comprises a revolving speed regulating potentiometer, a remote control signal receiver and a speed sensor, the control unit comprises a primary PID regulator, a secondary PID regulator, a pulse width modulating module, a power driving module and an actuator, and the feedback unit comprises a driving current feedback circuit and an actuator starting angle feedback circuit. The electronic speed regulator has the advantages of having a closed-loop control system which is formed by a revolving speed setting part, a speed measuring part, a comparing part, a computing part, a driving output part and the actuator. The electrified on-off ratio of the coil of the actuator is regulated to change the position angle of a connecting rod of the actuator, and a rack bar of an injection pump is pulled to determine the amount of oil inlet of an accelerator, thus enabling a diesel engine to work stably at a rated revolving speed under different loads or in a condition of continuously changed load, and leading to excellent dynamic performance. Simultaneously, the electronic speed regulator also has the advantages of high regulating accuracy and low-temperature shift.
