Distributed energy station intelligent operation and maintenance system based on digital twinborn technology

Abstract

The invention provides a distributed energy station intelligent operation and maintenance system based on a digital twinning technology, and the system comprises a data collection gateway, an Internet of Things platform, an object model module, a data fusion module, a fault diagnosis module, a decision management and control module, and a display module. The data acquisition gateway is connected with the Internet of Things platform, the internet of things platform and the object model module are both connected with the data fusion module, and the fault diagnosis module is connected with the internet of things platform; the data fusion module and the fault diagnosis module are both connected with the decision management and control module, and the display module is connected with the decision management and control module.According to the invention, the quantitative analysis and accurate positioning of the equipment faults can be realized, and further the accuracy of the device fault diagnosis is improved, and the intelligent operation and maintenance of the energy station devices are realized.

Description

technical field [0001] The invention relates to the technical field of energy station operation and maintenance, in particular to a distributed energy station intelligent operation and maintenance system based on digital twin technology. Background technique [0002] Distributed energy station refers to an energy center that centrally provides power, cold, heat, compressed air and other power for users. The energy station has a huge system and a large number of equipment, mainly including gas generators, waste heat boilers, lithium bromide refrigerators, and control systems and accessories. Electrical equipment, the coupling between equipment and the complexity of the system, and the complex operation of the equipment in the special working environment of high temperature, high pressure and high-speed rotation, there are many potential factors for failure. Once a failure occurs, it will force If the load of the unit is reduced, it will lead to downtime and even equipment dam...

Problems solved by technology

However, some fault causes are not very intuitive, and the parameters and state variables monitored by the system can reach hundreds or even thousands. It is necessary to judge the location of the fault from thousands of measurement parameters, state variables and alarm information, which will affect the operation of the unit. There are many factors in the situation, and the relationship between the factors is also very complicated. It is very difficult to accurately describe these uncertain factors.
