Theory and practice of smoke management system control logic of underground factory buildings of large-scale hydropower stations

Analyses the fire characteristics of underground factory buildings of large-scale hydropower stations. According to the requirements of relevant specifications, classifies the smoke management facilities of smoke management systems and ventilation and air conditioning systems. By analysing the cognitive deviation and problems of the existing projects, discusses the control logic relationship between the smoke control facilities and the automatic fire alarm system. Concludes that the danger and importance of hydropower project sites should be distinguished and corresponding measures should be taken to ensure the reliability of fire alarm control systems.
