Steam turbine heat regeneration method and system

The invention discloses a steam turbine regenerative method and system, and relates to the technical field of steam turbine regenerative control. And analyzing past power generation logs of the power plant, determining a plurality of unit influence factor groups, configuring a first unit driving strategy for the unit influence factor groups, and generating a unit driving strategy judgment model based on the corresponding relationship. And the unit driving strategy judgment model is used for analyzing the current unit influence factors, a second unit driving strategy is determined, the steam supply rate and the front feed water supply rate in the heat regenerator are determined, the steam supply rate and the front feed water supply rate in the second unit driving strategy are adjusted multiple times, and a third unit driving strategy is generated. And the temperature of rear feed water at the water outlet end of the heat regenerator is collected, based on the steam supply rate, the front feed water supply rate
