Partition evaluation method and system for deep peak regulation working condition of boiler

The invention discloses a boiler depth peak regulation working condition partition evaluation method and system. The method comprises the steps of obtaining original data of a power station boiler; performing data processing on the original data, establishing a relation curve graph of different power generation load average values and measuring point temperature average values of different heating surface components, and obtaining a relation curve graph of all the heating surface components; determining and marking inflection points in the relation curve graphs of all the heating surface components, wherein the inflection points are abrupt change points when the temperature average value of the measuring points is reduced along with the power generation load value; selecting a target heating surface component relation curve graph at the highest power generation load value corresponding to the material alarm temperature value of each heating surface component; according to the target heating surface component
