Performance Simulating of Electric-Liquid Compound Diesel Speed Governor Device

The model of electric-Liquid Compound speed governor device of the diesel was established, which makes simulations by use of Simulink and gives the dynamic curves of speed when load is changed and conducts an analysis on the influence of adjustable parameter on the dynamic process of speed governor device. The results show that the governor device can effectively inhibit the load disturbance, effectively improve the accuracy of the speed governor system and improve the frequency stability of the ship power system. The results can also provide the theoretic basis for taking necessary measures to improve the performance of the system during design and management.
