Guangdong Huasha Yangxi Power Plant SIS system: integrated intelligent management and control, release the potential of data!
As a bridge of data exchange between the plant management information system (MIS) and various decentralized control systems, the plant level monitoring information system (SIS) of Yangxi Power Plant covers the basic and advanced functions of real-time production data collection and historical data storage, B/S information release, plant level production process monitoring and management, etc., to realize the centralized monitoring, analysis and judgment of unit operating conditions. It provides real and reliable real-time operation data for the production operation and management decision optimization, so as to help the economic operation and benefit improvement of Yangxi Power plant through the integration of management and control.
Data interconnection, effectively break the information island!
Through SyncBase5.0, a large real-time database independently developed by SCIYON, the whole process of stable collection, safe transmission, efficient storage and efficient service is realized.
Stable acquisition: Data storage real-time acquisition interface software has good stability and slow storage and transmission ability, for network failure or server downtime and other emergencies will not cause the loss of real-time data, production process data to maintain complete consistency.
Safe transmission: data acquisition equipment and external network deployment of one-way physical isolation equipment, data only support one-way transmission from the acquisition equipment to the real-time database, blocking the external network of various types of hackers and virus attacks, while avoiding production monitoring system, management information system, etc. Impact on the production control network to ensure the network security of the control system.
The project real-time database has reached nearly 200,000 points of application scale, access to the production process data of all control systems, break the information barriers of each control system, realize the interconnection of the production process data of the whole plant, resource sharing, and lay a solid foundation for the integration and utilization of data. Since it has been put into operation, it has been running stably and efficiently, and its performance has reached the top level of similar products in the industry.
Process real-time monitoring, timely grasp the production situation!
Through on-line configuration technology and powerful graphics configuration graphics library, based on the original screen style of the control system, generate a variety of rich content and friendly interface graphics, synchronously restore to show the same process screen as the production site. Based on B/S architecture vector diagram technology, no need to install the client and any plug-in, just the browser can adapt to each resolution of the display, to achieve all monitoring pictures of what you see is what you get, and the use of simulation technology to achieve playback function, the real restoration of historical working conditions, production managers can be called at any time to view the production situation in each period.
Automatic report generation, efficient statistical scientific analysis!
Through the function of production statistics report, the production statistics of a large number of production data, automatically generate all kinds of economic and safety analysis reports, to help production managers timely understand the advantages and disadvantages of the power plant operation, and master the various factors and degrees affecting the economy and safety, to achieve a scientific analysis of the power plant production costs and operating conditions.
Performance/consumption analysis, dynamic optimization of unit operation!
Based on the characteristics of each unit of Yangxi Power Plant, through the customized real-time performance calculation, consumption analysis and online/offline performance test analysis model, real-time dynamic display of the performance characteristics of each unit and the impact of each parameter on coal consumption, to help the production operation and management personnel at any time to grasp the performance of each unit and the factors affecting the economic operation of the unit. To provide a reliable decision-making basis for optimization and adjustment, to ensure the efficient, safe and stable operation of the unit under the optimal working conditions, and to improve the efficiency and value-added of the enterprise.
Orderly management of equipment to ensure efficient operation of production!
Through the equipment reliability diagnosis model, the reliability and life of the whole plant equipment analysis statistics, automatic statistics of the reliability analysis data of the whole plant equipment, based on the fault data statistics and analysis to find the regularity of the cause, to help the power plant to fully grasp the operating status of the equipment, accurate location of equipment problems, provide basis for equipment regulation and optimization, to ensure efficient production operation.
Real-time benchmarking performance, fair evaluation and effective incentive!
The operation of the unit is mostly in a stable state, but there is no shortage of dynamic adjustment. In the adjustment process, the rationality of unit parameter changes is particularly important, and it is necessary to take into account various dimensions such as safety, economy and environmental protection.
Through the standard assessment function, the assessment range of corresponding parameters can be flexibly set according to the nature of parameters under different loads of the unit, scientifically balance each dimension, and automatically judge whether to enable assessment based on the load, real-time monitoring, real-time assessment, and automatic production of assessment results, so as to stimulate the operation personnel to actively carry out the whole process of monitoring and optimizing operation, and constantly improve the operation level. To ensure the efficient operation of the unit under the safe and environmental protection state.
Economic operation optimization, intelligent analysis to reduce costs and increase efficiency!
With the deepening of the reform of the power system, the separation of the plant network, the comprehensive promotion of bidding online, the continuous rise of power coal prices, the substantial increase in environmental protection investment, and the decline in the utilization hours of the unit brought about by the centralized production of new units, the efficiency of power generation enterprises has shrunk significantly, and the operating pressure is increasing. Reducing cost and increasing efficiency has become the main line of sustainable development of power generation enterprises.
Through load distribution, cold end optimization and other functions, based on intelligent analysis algorithm, the load of the whole plant can be reasonably distributed and the operation mode of the pump can be adjusted, so as to minimize the coal consumption and electricity load of the whole plant, ensure that each unit runs in the most economic state, effectively reduce energy costs and improve production efficiency.
The successful operation of the plant level monitoring information system (SIS) of Yangxi Power Plant has realized the real-time data extraction from the bottom, the establishment of the analysis model, and then the real-time feedback for the production and management personnel to assist the judgment and decision, and the operation guidance and suggestions for relevant operation adjustment through intelligent analysis, and the closed-loop management of the whole process of production. It has provided solid support for the improvement of the overall efficiency, the improvement of information technology and the stable, safe and economic operation of the whole plant.
With the continuous advancement of the "dual carbon" strategy, the traditional energy industry represented by thermal power has also been given a new mission. SCIYON will also continue to use independent innovation technology to enable more energy enterprises to improve efficiency, technology emission reduction, scheduling innovation and other transformation and upgrading, to help build a cleaner, low-carbon, safe and efficient energy system.
