Description

Technical Field

[0001] The present invention relates to the technical field of safety early warning technology for thermal power plants, and in particular to a safety early warning system for thermal power plants based on an edge data center. Background Art

[0002] As a vital energy supply base, the safe operation of thermal power plants is crucial for ensuring national energy security and economic development. However, thermal power plants may face numerous safety hazards during operation, such as fires and equipment failures. Accidents can cause significant economic losses and casualties. Therefore, developing an efficient and accurate thermal power plant safety early warning system is crucial for improving the safety and preparedness capabilities of thermal power plants. Traditional thermal power plant safety early warning systems rely primarily on centralized data processing, collecting monitoring data from various areas of the plant and transmitting it to a central server for centralized processing and analysis. However, this approach suffers from data transmission delays and low processing efficiency, making it difficult to provide real-time early warnings and rapid responses to thermal power plant safety hazards.

[0003] Chinese Patent Publication No. CN114757380A discloses a thermal power plant fault warning system, method, electronic device, and storage medium. The system includes a data acquisition module, a data management module, and a model construction module. The data acquisition module is used to obtain operating data for each power device in the current thermal power plant unit. The data management module is used to analyze the operating data to filter the model data required to construct fault warning models for different power devices and determine the operating characteristics of each power device. The model construction module is used to construct a fault warning model corresponding to each power device based on the model data and the operating characteristics of each power device, and then provide fault warning for the current thermal power plant based on each fault warning model. By combining the operating characteristics of each power device to construct a fault warning model for each power device in the current thermal power plant unit, faults in the power device are detected in advance and timely repairs are carried out, ensuring the stability of the unit operation. As can be seen, this invention only performs safety analysis on the thermal power plant generator unit and does not conduct a comprehensive safety analysis on the energy storage device and heat conversion device, resulting in low efficiency in thermal power plant safety monitoring.
