Abstract

The concept of a digital twin of an automated process control system (APCS) of a thermal power plants (TPPs) is considered. The principles of its formation and use are proposed on the basis of a design database developed within the framework of a computer-aided design (CAD) system for thermal automation and measurements. Examples of design automation systems aimed at solving similar problems are given and the features of the proposed CAD system are indicated. The typical structure of the APCS and the relationship of its main components—sensors, cables, executive and switchboard devices, signal connection tables, as well as the software and hardware complex (composition and distribution of modules of communication devices with an object)—are described. A description of the project database’s structure is given, which provides comprehensive work with both project documentation and information about the main components of the APCS. The sequence in execution of design procedures and links between the design database and the CAD database during their implementation are shown. Methods for increasing the productivity of designers are considered, such as the use of standard solutions in the organization of measurements and control schemes for actuators of thermal power plants, multiple use of information with a single input, and synthesis of text and graphic design documentation based on the project database. It is proposed to use a digital twin at all stages of the object’s life cycle: during design, installation, commissioning, and operation. The effectiveness of working with information thanks to an intuitive interface for navigating through the project was demonstrated. Examples of objects, in the implementation of which the considered CAD system was used, are given.

从TPP的APCS的自动设计到数字化双倍

摘要

考虑了火力发电厂（TPP）的自动化过程控制系统（APCS）的数字孪生的概念。它的形成和使用原理是根据在用于热自动化和测量的计算机辅助设计（CAD）系统框架内开发的设计数据库提出的。给出了旨在解决类似问题的设计自动化系统的示例，并指出了所提出的CAD系统的功能。APCS的典型结构及其主要组件（传感器，电缆，执行和配电盘设备，信号连接表以及软件和硬件复合体（带有对象的通信设备的模块的组成和分布））之间的关系是描述。给出了对项目数据库结构的描述，它提供了项目文档和有关APCS主要组件的信息的全面工作。显示了设计过程的执行顺序以及设计数据库和CAD数据库在其实现期间的链接。考虑了提高设计人员生产率的方法，例如在火力发电厂执行器的测量和控制方案的组织中使用标准解决方案，一次输入即可多次使用信息，以及基于文本和图形设计文档的综合在项目数据库上。建议在对象生命周期的所有阶段使用数字孪生子：在设计，安装，调试和操作过程中。展示了通过直观的界面浏览项目而使用信息的有效性。给出了对象的示例，在这些示例中使用了考虑的CAD系统。
