电子调速器具有调节精度高、易于实现多功能控制、易于实现远距离控制及全自动化控制,易于实现多台机组同步并联运行等特点,所以在柴油机燃料系统中采用电子调速器愈来愈引起人们的重视。本文着重介绍DT-30电子调速器的基本结构框图,并根据自动控制理论以及对柴油机全电调速系统实践经验建立了数学模型。数学模型边界条件的确定是以DT-30电子调速器同4120-30瓩发电机组构成的系统为例。用频率法对系统的稳定性进行了分析研究,并利用DMJ-3B型电子模拟计算机进行了模拟试验,通过改变系统参数求出系统动态过程的变化,为设计和调试提供了可靠的依据。
Electronic governor with high regulation accuracy, easy to achieve multi-function control, easy to achieve long-distance control and fully automated control, easy to achieve multiple units synchronized parallel operation, so the diesel fuel system using electronic governor more and more Aroused people’s attention. This article focuses on the basic structure of the DT-30 electronic governor block diagram, and based on the theory of automatic control and the diesel engine full speed governing system practical experience established mathematical model. The mathematical model of the boundary conditions to determine the DT-30 electronic governor with the 4120-30 瓩 generator system as an example. The stability of the system was analyzed by frequency method. The simulation experiment was carried out by using DMJ-3B electronic simulation computer. The change of system dynamic process was obtained through changing the system parameters, which provided a reliable basis for the design and debugging.
