에어/전기 기반 제조공정에서의 에너지 최적화 모델 연구

In this study, the actual air consumption of an auto parts manufacturing process has been simulated. its processes are composed of casting boilers, compressed air, foundry, precipitators, and etc.. these processes are using the air that is produced in each of the air compressor in accordance with the consumption of air. At this study, Mathematical optimization model has been made and simulated for the time number control method for optimizing the power consumption and the results have been compared with the conventional control method and the possibility of energy saving by optimization management has been evaluated than conventional control method. The results has shown as follows: Compressed air consumption and the electric cost by optimization process has showed more than 18% savings when it has manufacturing process in accordance with the air compressor operating scenario by conventional air compressor control method
