2020In that year, our company began to implement the "Integrated Platform for Work Safety and Equipment Control" project of Shaanxi Jinjie Power Plant of National Energy Group. This project includes: a visualized early warning and intelligent diagnosis system for major auxiliary equipment faults, a visualized safety pre-control system for steam turbine generator sets, a three-dimensional visualized client for the status of unit equipment, and a visualized monitoring system for the status of unit equipmentAPP,AREquipment inspection system.

Project Introduction

1. The integrated platform for work safety and equipment control is mainly based on the comprehensive integration of detection data. It utilizes 3D modeling technology, data mining technology, intelligent diagnosis technology, and integrates expert knowledge in equipment management. It enables front-line production personnel, middle-level production managers, and factory-level decision-makers to work collaboratively on a unified multimedia display platform. Achieve the application goals of enhancing the reliability of power plant equipment, system optimization, energy conservation and consumption reduction, and operation and maintenance decision-making.

2. The platform, based on big data mining and refinement, establishes a visualized full-plant model, equipment-level modeling, builds a digital twin power plant, and realizes equipment status, process simulation and modeling, and business training functions.

3. System establishmentARInspection system, optimizing the inspection process, combining virtual and real elements.

Implementation effect

1. The commissioning of the system not only standardizes the daily work of operation and maintenance personnel, but also realizes the visualization of the status of important auxiliary equipment. It enables people to understand the operation status of the equipment without going to the site, thereby improving work efficiency. The daily collected data were summarized and analyzed, providing data support for equipment evaluation. The establishment of a three-dimensional model makes the analysis of problems more intuitive. InspectionARThe intervention of equipment enables inspection personnel to understand the structure of equipment and the points of equipment failure without having to search through a large number of equipment ledgers. In coordination with the construction of the intelligent control system, a solid foundation has been laid for the subsequent construction of intelligent power plants.

2. The "Visual Auxiliary Equipment Intelligent Safety Pre-Control System" enables users to have a comprehensive understanding of the health status of all important auxiliary equipment through the list of their health status. It also allows for detailed diagnostic analysis to identify the causes of faults and determine the faulty locations. It provides important reference indicators for maintenance personnel;

3. The "Visual Safety Pre-Control System for Steam Turbine Generator Sets" features visual intervention, allowing for intuitive viewing of the operational status and parameters of key bearing positions in each steam turbine. Combined with the diagnostic system, it can also conduct trend analysis and result orientation. No need to master expert-level knowledge; Then one can understand the expert-level analysis conclusions.

4. The "3D Visualization Unit Equipment Status Client", a 3D visualization client, has conducted full-scale modeling from the entire plant's buildings to the equipment, and has been detailed down to the component level. When an abnormality occurs in a certain device, it can be quickly located and a prompt alarm will be issued promptly. This provides a solid foundation for the subsequent intelligent construction of the entire factory.

5. "Visualized Monitoring of Unit Equipment StatusAPP"APPIt integrates all the important data of the auxiliary machine system and the turbine system, enabling maintenance personnel to understand the operational health status of the equipment through their mobile phones.

6. "ARThe inspection personnel of the "Equipment Inspection System" no longer need to carry a large number of detection tools. By scanning the QR code of the equipment, they can view the inspection process, inspection standards, and also check real-time operating parameters, maintenance ledgers, health status, expert suggestions and diagnosis.
