Study on the Output Range of Thermal Power Units under Heating Conditions based on Data-driven Technology
To solve the heating problem in cold northern regions,thermal power units usually require heating and steam extraction during winter.In the context of the"dual carbon target",thermal power has gradually become the mainstream provider of power system regulation capacity,and research on the out-put range of thermal power has become increasingly important.This article first relies on artificial intelli-gence methods to establish a coupling model of main steam flow rate,heating extraction rate,exhaust rate,and power based on historical operating data of the unit.Then,combined with the constraints of the unit's own main steam range and minimum exhaust rate,the upper and lower limits of thermal power unit output under different heating extraction rates are explored.Finally,the constraint range of the proposed method is verified to be feasible based on unit data.
