摘要
以原物理系统（调速器－ 喷油泵－ 柴油机）为基础，增加一个能功转换环节来考虑燃料经燃烧、膨胀作功过程的影响，建立了一个四元调速系统功能模型，能够更加精确地描述机械式调速系统的工作机理；利用自动控制理论对调速系统的稳定性进行判断，以一典型的柴油发电机组（装配ＲＳＶ型调速器）标定工况“突卸”试验为对象，对调速系统的动态调节过程进行了计算机仿真，计算结果与瞬时转速实测曲线较为一致，表明理论分析方法是正确、有效的；另外，在模拟计算基础上，运用质量向量法对调速系统的动态调节过程进行了参数优化，以揭示设计参数对系统性能的影响，从而获得最佳的设计方案。
An energy transition block was added to the previous physical system (governor pump engine),which was employed to investigate the factors of fuel combustion and expansion work,so a four blocks function model of governing system could be set up to describe the working mechanism of mechanical governing system more accurately;The stability of governing system was judged by means of the automatic control theory,as an example,a typically dynamic “sudden download” process under capacity condition of a diesel generator set (equipped with RSV governor) was simulated,and its characteristics coincide well in general with the momentary speed test,therefore,the calculation analysis was proved to be valid and effective;Additionally,based on the simulation approach,The vector performance method was applied to optimize the system parameters,furthermore,its effect on the governor system transient behavior was revealed,and the optimal design was obtained.
