【摘要】 船用发电柴油机的转速控制和负荷限制是由液压调速器来实现的,液压调速器的特性直接决定了发电机组的性能,加强学员对液压调速器工作特性了解和训练是轮机模拟器训练的重要内容之一。在现有轮机模拟器中,发电柴油机液压调速器的仿真模型过于简化,无法进行更深层次的培训和训练任务。根据调速器的工作原理和轮机模拟器训练目的,建立了UG8调速器的数学模型,结合柴油机Seiliger模型进行了仿真,并将仿真结果与台架实验进行对比分析,仿真误差小于3%,表明了调速器建模的准确性与可靠性。该模型在轮机模拟器的研制与培训中具有一定的实用价值。更多还原

【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.更多还原
