Research on speed control of marine diesel generator assisted by PLC
When diesel generators are subjected to external disturbances during operation,the fluctuation amplitude of their speed increases,which affects the output stability and efficiency of the generator.Therefore,this paper proposes a PLC assisted speed control method for marine diesel generators.Based on the basic working structure of diesel generators,con-struct and analyze models of their various components.By analyzing the parameters and characteristics obtained from each component model,starting from both static and dynamic perspectives,the speed control indicators of ship diesel generators are selected,including static error rate,overshoot,and dynamic descent.By combining the above indicators with PLC pro-gram logic,the current status is determined by monitoring real-time data,and then the control parameters are adjusted based on feedback information to effectively control the speed of the diesel generator.The experimental results show that the meth-od proposed in this paper can adjust the speed of the diesel generator more quickly,and can quickly adjust and return to a stable operating state when disturbed by external forces,ensuring the long-term stable operation of the diesel generator.
