水利水电工程通风控制系统设计技术研究

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

摘要

水利水电工程通风系统的良好运转，对工程的安全运行非常重要。通风控制系统是保证整个通风空调系统有序、稳定、可靠运行的基础，其设计主要从系统结构、组网方式、末端控制回路、与其他系统联动方式等多方面进行考虑。根据水利水电工程的建筑物通风控制区域、投资要求、业主要求、设计理念等因素，可有针对性地进行不同设计方案选择。阐述水利水电工程在不同的工程条件下对通风控制系统进行选择性的分类设计，对提高设计效率、结构稳定性、节约项目成本等多方面具有重要意义。同时，总结出使用星型以太网网络、配置纯继电器回路和小型PLC,并使用网络联动火警停止非消防风机的通风控制设计方案，在清原抽水蓄能电站中实践并验证了其先进的设计思路。最后，通过多年的设计经验，延伸探讨了未来通风控制系统发展的趋势及目标。

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.
