Thermal power plant boiler staged combustion control method and system

Abstract

The invention relates to the technical field of boiler combustion, in particular to a thermal power plant boiler staged combustion control method and system. Comprising the following steps: setting a plurality of sub-combustion areas according to boiler equipment parameters, and setting an initial control strategy of each sub-combustion area according to a preset control model; establishing a plurality of adjustment periods, and setting a first-level correction strategy of each adjustment period according to a preset correction model; monitoring data packets of all the sub-combustion areas are obtained according to preset feedback time nodes, and whether an adjusting instruction is generated or not is judged according to all the monitoring data packets; according to different boiler equipment parameters, corresponding sub-combustion areas are constructed, initial control strategies of all the sub-combustion areas are set based on historical parameters, rapid adjustment of boiler staged combustion is achieved, by additionally arranging a correction model, the initial control strategies of all the sub-combustion areas are dynamically adjusted according to different fuel parameters and environment parameters, and the boiler staged combustion efficiency is improved. Therefore, the control precision of boiler staged combustion is improved.
