摘要
引水隧洞压力管道是引水发电系统安全监测中的重要环节。通过安全监测自动化系统的离线分析功能,对小湾水电站2号机组压力钢管下平段反馈的监测数据进行分析,建立对压力管道安全性态的初步认识,推断压力钢管空鼓的成因。根据监测数据分析结果,为机组的安全运行和维护提供合理、可靠的决策信息。
The penstock of diversion tunnel system is an important part of diversion-generating system safety monitoring in a hydropower station. Through using the off-line analysis function of automatic safety monitoring system, the monitoring data of lower horizontal section of penstock of Unit 2 in Xiaowan Hydropower Station are analyzed. And then the safety state of penstock is preliminarily understood and the causes of hollowing around penstock are deduced. The analysis results provide reasonable and reliable decision-making information for the safe operation and maintenance of unit.
