Abstract: Taking the parallel operation of two diesel generators as an example,a dual engine parallel control system is established. The parameters such as power, voltage and frequency are dynamically monitored by the measurement unit to control the self start,grid connection and disconnection of diesel generators. The total load power is calculated through the speed characteristics to realize the average power distribution of parallel units and ensure the stable operation of parallel units. The feasibility and accuracy of the method are effectively verified by simulation analysis.
