Thermal power plant equipment property evaluation and early warning method and system based on industrial internet

Abstract

The invention provides a thermal power plant equipment property evaluation and early warning method and system based on the industrial internet. The method and the system can solve the problem of the wide gap between original operating data of equipment and equipment property management. The method comprises the steps that an equipment data model is generated according to the historical operating data of the equipment, and by correcting the equipment data model in real time according to real-time operating data of the equipment, an equipment dynamic model is generated; the equipment dynamic model is used for analyzing the real-time operating data of the equipment to generate a predicated value, and the predicated value and a site measured value are analyzed and compared to evaluate the equipment property; early warning is carried out for potential faults of the equipment. The system comprises a dynamic model generating unit used for generating the equipment dynamic model, a property evaluation unit used for evaluating the equipment property, and a fault early warning unit used for carrying out early warning for the potential faults of the equipment. The method and the system are suitable for the technical field of communication.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to an industrial Internet-based thermal power plant equipment performance evaluation and early warning method and system. Background technique [0002] In recent years, with continuous rapid economic growth, a new round of power construction is in full swing. At the same time, with the centralized operation of new thermal power plants, the Supervisory Information System in plant level (SIS) is also being implemented in China. Thermal power plants are rapidly gaining popularity. Through the construction of the SIS system, the input of the information system of the thermal power plant and the production management of the thermal power plant can be combined more closely. The SIS system effectively resolves the gap between production control and production management. Since the SIS system is a plant-level application, with the new thermal power plant put into operation, the cont...

AI Technical Summary

Problems solved by technology

DCS and SIS databases collect and save a large number of original operating data of equipment, while equipment maintenance management systems such as equipment preventive management and maintenance and equipment performance evaluation expert systems need dynamic performance data of equipment. At present, equipment data collection and There is still a lack of a unified equipment performance management platform between equipment status performance analysis and processing, which makes it very difficult to evaluate the online performance of plant-level equipment
