Abstract

The invention discloses a DCS based performance monitoring method and device of a thermal power set. Operational processing and residual error analysis are carried out on real-time operation data measuring values, sent by a DCS, of the thermal power set, obtained deviation calculating value, power-plant generating efficiency and power-plant power supply efficiency are returned to the DCS, and thetechnical problem of high investment due to the fact that a present online performance analysis method and monitoring system include an independent online performance analysis and monitoring system which needs external computer equipment and a lot of independent hardware equipment is solved.

Description

technical field [0001] The invention relates to the field of thermal power generation measurement and control, in particular to a DCS-based thermal power unit performance monitoring method and device. Background technique [0002] At the present stage, as a power generation unit, thermal power plants need to provide better quality and low energy consumption electricity under the background of "energy saving and emission reduction" and on the premise of meeting social needs. To achieve these goals, it is necessary Power generation enterprises have a comprehensive understanding of the performance of their own units and accurately estimate their own power generation costs. [0003] Existing online performance analysis methods and monitoring systems include independent online performance analysis and monitoring systems. The independent online performance monitoring and analysis systems require external computer equipment and a large number of independent hardware equipment, resu...
