Device and method for managing historical data of thermal power generating unit

Abstract

The invention discloses a device and method for managing historical data of a thermal power generating unit, and the device comprises a work condition setting and querying interface machine, a first data exchange module, a first computing center, a second computing center, a second data exchange module, a first unit historical data center and a second unit historical data center. The work condition setting and querying interface machine is connected with the first data exchange module through an Ethernet, and the first computing center is connected with the first and second data exchange modules through the Ethernet. The second computing center is connected with the first and second data exchange modules through the Ethernet. The first unit historical data center is connected with the second data exchange module through the Ethernet, and the second unit historical data center is connected with the second data exchange module through the Ethernet. The invention also discloses the method for managing historical data of the thermal power generating unit. The device is simple in structure, employs distributed storage and parallel computing, and provides a multi-dimensional input and unit operation simulation interface.

Description

technical field [0001] The invention belongs to the field of historical data management of thermal power plants, and in particular relates to a device and method for managing historical data of thermal power units. Background technique [0002] During the production process of thermal power plants, the control system measures and stores various operating parameters and measurement data of the unit in real time. The historical data of thermal power unit operation is of great value. It records the operating status of the unit under different working conditions and conditions. It is a very important resource for scientific researchers and equipment manufacturers. If in the process of design and product testing Using these data for simulation will be closer to the field environment and the actual situation of the unit. At present, the historical data of thermal power plants is stored in the historical data server of the control system, which only supports simple historical data...

AI Technical Summary

Problems solved by technology

At present, the historical data of thermal power plants is stored in the historical data server of the control system, which only supports simple historical data query and access, and the access speed is slow. It does not support complex conditional query, operation simulation, and high-speed access to historical data, etc.
