Problems solved by technology

The small index analysis method is difficult to comprehensively coordinate the optimization relationship between small indexes, and it is difficult to solve the evaluation problem under different objective operating conditions. Therefore, it has produced some negative effects in the competition. The main problems exposed are: one-sided pursuit of a single small index, Neglecting the overall economics of unit operation, simply emphasizing that each small index is operated at the limit value, which does not reflect the best comprehensive benefits of the entire unit
[0004] The unit operation optimization m

Example Embodiment

[0012] The system downloads the temperature, pressure, power, flow and other parameters related to the operation of the unit to the local database through the DCS data interface every five minutes, analyzes and calculates the deviation values ​​of several parameters that affect the economy of the unit through the cost deviation analysis module, and through the performance calculation The economic indicators of the modular computer group include: unit power consumption rate, steam turbine heat consumption, high-pressure cylinder efficiency, boiler efficiency, unit power generation coal consumption, unit comprehensive power generation cost, unit power supply coal consumption, unit main auxiliary machine power consumption, unit gross profit etc. in the system process picture The display window displays the actual value of the main parameters, the comprehensive performance index of the unit, the real-time operating cost and gross profit of the unit, and intuitively reflects the pr...

Abstract

This invention puts forward an intelligent unit performance optimized operation management method of a computer, which obtains the unit operation parameter via a boiler control system, obtains the carbon volume in the ash of the boiler from a test device, gets related parameters of factory electricity consumption from an electric transcription system to store real time operation data in a data base server of a central process computer and compute a set of economic targets under the current operation situation to provide the optimum economic operation parameter taking the least cost of electricity as the searching target. Advantage: combining the several single parameters to a comprehensive target expressing the set operation integral effect and directly combining with the profit target of the enterprise to save energy for the generation enterprises.

Description

technical field [0001] The invention proposes a computing intelligence-based performance optimization operation management method of a unit, which belongs to the technical field of coal-fired boiler combustion optimization in power stations. Background technique [0002] At present, there are still many domestic power plant operators who can see the relevant parameters of unit operation in the DCS system in time, such as single indicators such as exhaust gas temperature, oxygen content, main resteam temperature, and steam pressure, etc., but cannot see them in time. The real-time economic indicators of the unit, and what is unreasonable in the operation mode at that time, often cannot be known until the next day or even the next day after professional analysis. This kind of lagging analysis cannot provide timely and effective operation guidance to operators, which is also an important factor that makes it difficult to further improve the economic level of unit operation. ...
