- 摘要:
- 抽水蓄能工程是我国大力推进能源结构转型的重要支撑,其中消防供水系统是保障电站安全运行的关键组成。不同于民用建筑中相对稳定的消防水池水位,抽蓄工程的水位变幅一般为20~40 m且变动较为频繁,保障厂房各部位消火栓在不同水位工况下均能安全稳定使用,是消防供水系统设计的重难点。通过对4类水位工况组合进行分析,兼顾最不利消火栓灭火压力要求和最低处消火栓防超压要求,总结了对应的消防供水系统布置方案,并提出了一种端部切换式减压供水系统。介绍了系统关键设计要点、计算方法、控制逻辑,并进一步提出了末端减压及源头减压措施,定量化分析了各类减压措施的适用范围,可为类似工程提供参考。
- Abstract:
- The pumped storage project serves as a crucial support for promoting the transformation of the energy structure in China, among which the fire protection water supply system is a key component that ensures the safe operation of the powerhouse. Different from the relatively stable water level in fire pools of civil buildings, the water level of pumped storage projects typically fluctuates between 20 and 40 meters with considerable frequency. Ensuring the safe and reliable operation of fire hydrants throughout the powerhouse under varying water levels constitutes a key and difficult point in the design of fire protection water supply system. Through the comprehensive analysis of four types of water level conditions, while considering the requirements for the most unfavorable fire hydrant pressure and the prevention of overpressure at the lowest fire hydrant, the corresponding fire protection water supply system layout schemes were developed. Furthermore, an end-switch type pressure-reducing water supply system was proposed. This paper introduced the key design aspects, calculation methodologies, and control logic of the system. Furthermore, it proposed measures for end decompression and source decompression, and conducted a quantitative analysis of the applicable scope of these measures, providing a valuable reference for similar projects.
