基于CAN总线的柴电机组控制系统策略研究与实现

为提高孤岛有限容量系统的稳定性和经济性，通常采用多台同型或异型发电机组并机运行的方法来实现系统的输出扩容。机组的并机控制、负荷分配策略是决定系统运行稳定的核心因素，因此设计了一种基于CAN总线的柴电机组控制系统。首先，针对CAN总线控制系统进行总体设计；然后，针对柴电机组并机运行要求，对其调速、调压、负荷均衡分配控制策略进行分析研究，制定了并机控制、负荷分配策略；最后，结合工程应用案例，成功实现了该控制系统在同型/异型机组间的应用，该系统还具有完善的发动机燃油控制、故障诊断功能。

Research and Implementation for Diesel Generator Sets Control System Strategy Based on CAN Bus

In order to improve the stability and economy of the island limited capacity system, multiple same type or different type generator sets are operated in parallel to realize the output expansion of the system. The parallel control and load distribution strategy of the generator sets are the core factors which determine the stability of the system. Thus, a diesel generator sets control system is designed based on CAN bus. Firstly, the integrated design for the CAN bus control system is carried out. Secondly, according to the requirements of parallel operation of the diesel generator sets, the control strategies of speed and voltage regulation, and load balancing distribution are analyzed and studied. The parallel control and load distribution strategies are formulated. Lastly, combined with engineering application cases, the application of the control system is successfully realized for the same type and different type generator sets. The system also has perfect engine fuel control and fault diagnosis functions.
