[0061] 1. System technical architecture

[0062] Utilize the existing PI real-time database server and Oracle relational database for data storage and transmission; configure the application server and Web server for data calculation, analysis and application, and Web publishing and remote access of information, all servers It is isolated from the external network by a firewall. After the firewall is configured, end users can access it safely in B / S mode. It is divided into four levels from bottom to top: data access layer, business logic layer, presentation layer, external interface and terminal access layer. The system technical architecture is as follows: figure 1 shown.

[0063] ① Data access layer

[0064] The data access layer is located at the bottom of the system platform, and is used to receive and store real-time data and relational data uploaded by the data collection platform on the plant side. Real-time data is mainly used to transmit and store "second-level" ...

Abstract

The invention, which belongs to the technical field of the gas-steam combined circulating generating system, relates to a big-data-based remote energy efficiency diagnosis method for a gas-steam combined circulating generator set. According to the method, under the big background of continuous accelerated fusion of industrialization and informatization, original operation parameters, collected at field, of a gas generator set are integrated and analyzed by an internet-based group private network. The system is composed of a real-time database and a relation database, a configuration application server, and a web server; the databases are used for data storage and transmission; the configuration application server is used for data calculation, analysis and application; and the web server is used for information web issuing and remote access. The diagnosis method includes: data acquisition, data information integration and analysis, data determination, on-line set operating state monitoring, real-time and on-line performance index calculation, operating parameter statistic analysis, performance index statistics and data mining analysis, and set benchmarking management.

Description

technical field [0001] The invention relates to a remote energy efficiency diagnosis method for a gas-steam combined cycle power generation set based on big data, and belongs to the technical field of gas-steam combined cycle power generation systems. Background technique [0002] At present, the energy efficiency evaluation of domestic gas-steam combined cycle power generation units mainly refers to the design parameters of the rated working conditions of the units or the operating experience of the units. Some of the current optimal operating values ​​are caused by equipment aging and defects, which cannot effectively evaluate the energy efficiency level and energy loss of the unit. Moreover, our country mainly relies on the introduction of foreign gas turbine generator sets, and has less control over the units than domestic coal-fired units. It lacks comprehensive diagnosis and optimization of the thermal system, especially the economic quantitative analysis of local chan...
