摘要

基于朗肯循环的大型热电发电系统需要监测由于侵蚀和加速腐蚀等老化过程引起的蒸汽流引起的管壁变薄。检测困难与恶劣环境(50℃和100%相对湿度)和具有复杂几何形状的空间有关,例如管道曲线及其支撑结构。这项工作提出了一个监测程序,该程序集成了机器人系统和工业4.0技术进行的壁厚检查,以处理收集的数据并在整个组织中传播信息。机器人系统使用“数字孪生”技术开发,这是一种非常逼真的虚拟建模方案,允许与现实世界环境进行交互。它们包括设备和执行检验过程的所有步骤。该管壁厚监测系统将用于安格拉1号核电站(巴西)。

Nuclear engineering for monitoring the thinning of the pipe wall of the Angra 1 power plant
Large thermoelectric generation systems based on the Rankine cycle require monitoring of the thinning of the pipe wall caused by steam flow due to aging processes such as erosion and accelerated corrosion processes. Inspection difficulties are related to hostile environments (50 oC and 100% relative humidity) and spaces with complicated geometry, such as pipeline curves and their support structures. This work presents a monitoring program that integrates wall thickness inspections performed with a robotic system and Industry 4.0 technology to process the collected data and disseminate information throughout the organization. The robotic system is developed using “Digital Twin” technology, a very realistic virtual modeling scheme that allows interaction with the real world environment. They include equipment and all the steps to carry out the inspection process. The tube wall thickness monitoring system will be used at the Angra 1 nuclear power plant (Brazil).
