M310核电机组循环水系统过程信号传输方案研究

Research on Process Signal Transmission Scheme of Circulating Water System of M310 Nuclear Power Plant

近年来,国内多个核电机组发生海洋生物涌入循环水过滤系统取水口事件,将冷源相关系统过程信号安全可靠地送入主仪控系统至关重要。本文对几种常见的信号传输方式进行了分析和研究。其中,远程I/O技术在项目实践中取得了良好使用经验,为后续机组方案设计积累了宝贵经验。

In recent years,there have been incidents of marine organisms flooding into the water intake of the circulating water filtration system in a number of nuclear power plants in China.It is very important to send the process signals of the cold source related system to the main instrument and control system safely and reliably.In this paper,several common signal transmission methods are analyzed and researched.Among them,the remote I/O technology has obtained good experience in project practice,and has accumulated valuable experience for the subsequent unit scheme design.
