A technical study on the design of the ventilation control system for water conservancy and hydropower projects

Abstract

The good operation of ventilation system of water conservancy and hydropower project is very important for the safe operation of the project. ventilation control system is the basis for ensuring the orderly, stable and reliable operation of the entire ventilation air conditioning system. Its design mainly considers the system structure, networking mode, terminal control loop, linkage mode with other systems, etc. According to the different control areas, investment requirements, owners' requirements, design concepts and other factors of the building ventilation of water conservancy and hydropower projects, different design schemes can be selected. The classification design of selectivity for ventilation control system in water conservancy and hydropower projects under different engineering conditions was described, which is of great significance in improving design efficiency, structural stability, saving project costs and other aspects. At the same time, the ventilation control design scheme is summarized, which uses star Ethernet network, pure relay circuit and small PLC, and uses network linkage fire alarm to stop non fire fan. Its advanced design idea is practiced and verified in Qingyuan Pumped Storage Power Station. Finally, through years of design experience, the author also extended and discussed the future development trend and goals of ventilation control system.
