摘要

随着人工智能、数字孪生技术及数字化虚拟技术的快速发展，采用数字化虚拟技术实现电站直接空冷机组空冷岛运行状态的实时监测成为可能。首先，建立空冷岛三维模型，通过数值计算获得空冷岛空气状态参数，开发空冷岛运行状态数据库及显示和查询软件；其次，基于数字孪生技术，在电厂设置气象站，获得环境气温、风速、风向实时变化数据，连同机组运行工况参数输入监测软件；最终，计算获得空冷岛空气运行状态并进行三维显示。基于数字孪生技术的空冷系统空气运行状态实时显示技术避免了现场大量装设测点的投资和检修维护工作，为智慧电站的发展奠定了基础。

Abstract

With the rapid development of artificial intelligence

virtual reality and augmented reality technology

it is possible to realize real-time monitoring of operation state of air cooling island of direct air cooling unit by using digital virtual technology. Firstly

a three-dimensional model of the air-cooled island is established

and the operating state parameters of the air-cooled island are obtained by numerical calculation. The air-cooled island operating state database and display and query software are developed. Secondly

based on the concept of digital twin

a meteorological station is set up in the power plant to obtain real-time change data of ambient temperature

wind speed and wind direction

and the operating conditions of the unit are used as software input parameters.Finally

the operation state of the air-cooled island is calculated and displayed in three dimensions. The real-time display technology for air operation state of air cooling system based on digital twin avoids the investment and maintenance of a large number of measuring points on site

which lays a foundation for the development of intelligent power stations.
