Abstract

The invention discloses a power plant boiler combustion intelligent control method. The method comprises the following steps: (1) historical operation data are fused; (2) the historical operation data after fusion are traversed, error detection is carried out, error data are eliminated, steady-state operation condition data are screened, certain operation condition data in the steady-state operation condition data are removed, and the remaining steady-state operation condition data serve as training samples; (3) a training sample library is built, coal quality characteristic parameters and boiler control parameters serve as input parameters, combustion effect parameters serve as output parameters, and a boiler integrated combustion prediction model is built; and (4) global sensitivity analysis is carried out on the boiler combustion effect parameters, sensitive boiler control parameters in the boiler combustion effect parameters and a sensitive interval are obtained, a heuristic optimization algorithm is then adopted to realize optimization of the boiler control parameters, and thus, intelligent optimization control on the boiler is realized. Modeling is carried out based on the rich historical operation data of the power plant boiler, and the practicability is good.

Description

technical field [0001] The invention belongs to the technical field of intelligent control, and more specifically relates to an intelligent control method for boiler combustion in a power station. Background technique [0002] The "Made in China 2025" action plan puts forward higher requirements for intelligence, high efficiency, and green environmental protection in the field of power equipment, one of the ten key breakthrough development areas. The intelligence of power generation equipment is the direction of future development. As one of the most important power generation equipment, power plant boilers have high safety requirements and complex control logic. Boiler combustion intelligence is the core of the entire coal-fired power generation enterprise to achieve intelligence, and it is also a difficulty. At present, large-scale power plant boilers are generally controlled by a distributed control system (DCS), and automatic control is realized according to preset contr...
