Abstract：In order to reduce the cost and power fluctuations of generator units for stable and sufficient power supply, the characteristics of islanded power demand and different generator are analyzed. Based on the power demand and operating load, the parallel power generation mode of gas and diesel engines is selected, and a power management system is designed. The effectiveness of unit power generation and management system is verified by experiments. The results show that the power management system could control the gas engine and diesel engine to cut in and out of the islanded power system according to the power demand, so as to realize the automatic start and stop of the units, multi-generator parallel connection and even load distribution. The power fluctuation of each generator is less than ± 10 kW, which not only ensures sufficient power supply, but also reduces the cost.
