Abstract

The invention discloses a control method and device for a generating set. Wherein, the method includes: determining the coal-burning influencing factors of the generating set, wherein the coal-burning influencing factors at least include: the secondary air volume adjustment method of the boiler, the outlet temperature of the coal mill, the speed of the separator corresponding to the coal mill, the coal The quality factor, the generator set includes: boiler, coal mill; the influence factors of coal combustion are corrected to obtain the corrected coal combustion influence factors; the AGC signal of the generator set is determined based on the corrected coal combustion influence factors, wherein, in the generator set Multiple devices operate based on the AGC signal. The invention solves the technical problem in the related art that the combustion performance of the boiler used by the generating set cannot be coordinated and optimized.

Description

technical field [0001] The present invention relates to the technical field of generator set control, in particular to a control method and device for a generator set. Background technique [0002] The bottleneck of the coal-fired thermal power generation unit affecting the speed of the unit is the boiler. The combustion effect of the boiler, especially the combustion performance during the load change period, is not only related to the safe operation of the generator set, but also affects the power of the boiler quick response generator set. There are many factors that affect boiler combustion, such as coal type, oxygen content, pulverized coal fineness, secondary air temperature, air powder mixture temperature, and so on. Therefore, in the combustion process of the boiler, ensuring that the proportion, quantity, and time point of combustion elements such as air coal and other combustion elements are coordinated and optimally controlled can greatly improve the combustion pe...
