Problems solved by technology

[0003] For coal-fired power plants, although the traditional pollutant concentration control has been shifted to the total amount control, in the specific implementation of the total amount control, after the initial allocation of the total emission amount, the dynamic and planned management of the actual emission amount has not been realized, resulting in Unexpected excess emissions from power plants and regions have brought certain challenges to power generation companies and relevant government departments to implement precise control of total pollutant emissions

Embodiment Construction

[0035] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0036] The intelligent decision-making method for controlling the total amount of pollutant discharge in coal-fired power plants of the present invention is mainly divided into the following two parts in the specific implementation process:

[0037] One, such as figure 1 As shown, to calculate the annual excess emission or emission reduction of a single unit, the calculation process is as follows:

[0038] 1-1) Use the coal-fired power plant pollutant discharge online monitoring system to calculate the actual total pollutant discharge from the beginning of the year to the target month.

[0039]1-2) Calculate the pollutant emission control target from the beginning of the year to the target month according to the annual total pollutant discharge control target of the unit and weight the electricity factor, and then calculate the pollu...

Abstract

The invention discloses an intelligent decision-making method for controlling the pollutant discharge total amount of a coal-fired power plant. An initial distribution target of the discharge total amount is decomposed, the actual discharge amount is dynamically tracked, the capacity of the pollutant discharge total amount of a coal-fired unit is analyzed, a multi-target linear programming theory is applied, power generation enterprises and relative government sectors are guided to timely conduct and execute dynamic total amount control strategies such as internal regulation and regional balancing of the discharge total amount, and the target maximization of the power generation enterprises, regional environmental benefits and economic benefits is achieved.

Description

technical field [0001] The invention relates to an intelligent decision-making method for controlling the total amount of pollutant discharge in a coal-fired power plant, and belongs to the technical field of automatic control of electric power systems. Background technique [0002] my country began to introduce the idea of ​​total amount control in the 1980s, and carried out theoretical and practical explorations. In the "Ninth Five-Year Plan for National Economic and Social Development of the People's Republic of China and the 2010 Outline of Long-term Objectives", it was clearly stated that the main pollutants should be implemented total emission control. At present, the total amount control adopted by China macroscopically is the target total amount control, and the allocation of my country's total amount control indicators basically adopts a "top-down" model, that is, the country takes the actual emissions declared by each province (district) as the benchmark. After veri...
