大型抽水蓄能电站防水淹厂房事故演算与风险分析
|
摘要
水淹厂房是水电行业重要风险之一。对于地下厂房,一旦发生水淹厂房事故,设备损坏较地面厂房将更严重,人员的疏散难度更大,因此抽水蓄能电站提升防水淹厂房能力的研究具有十分重要的意义。以PJ抽水蓄能电站为具体分析对象,针对不同爆管部位引起水淹厂房的情况进行事故工况模拟演算,分析不同的工程条件下,淹没速率及淹没高度的差别,为抽水蓄能电站设计、建设、运行和管理提供借鉴。
The water flooding of powerhouse is one of important risks in hydropower industry. For the underground powerhouse,the occurrence of powerhouse water flooding accident will cause more serious equipment damage than that in ground powerhouse. Therefore,the research on the capacity of pumped-storage power station to improve powerhouse water anti-flooding is important. Taking PJ pumped-storage power station as study object,the accidents of powerhouse water flooding caused by different pipe bursts are simulated,and the submergence rates and submergence heights under different engineering conditions are analyzed to provide references for the design,construction,operation and management of pumped-storage power stations.
