doi:10.16182/j.issn1004731x.joss.201803021

Abstract

Abstract: The speed control and load limit of marine diesel engine are implemented by hydraulic governor, of which the characteristics directly determines the performance of generator set. Therefore, it is an important content of marine engine room simulator training to strengthen the students’ training and understanding of the working characteristics of the hydraulic governor. In the existing marine engine room simulators, the simulation model of hydraulic governor is too simple to carry out further training tasks. According to the working principle of hydraulic governor and the training purpose of marine engine room simulator, the mathematical model of UG-8 hydraulic governor is established. Combining with the diesel engine Seiliger model, simulation is conducted and the simulation error is less than 3% compared with the bench test, which indicates the accuracy and reliability of the proposed hydraulic governor model. This model has certain practical value in the development and training of marine engine room simulator.

Key words: marine four-stroke diesel engine, hydraulic governor, Seiliger model, simulation
