Abstract

The embodiment of the present invention provides a steam turbine regulation system and method that introduces overshoot peak correction. The embodiment of the present invention adds an overshoot peak correction module and / or initial The step delay module is used to eliminate the influence of the generator side on the model parameters of the steam turbine regulating system and the influence of the volume delay of the steam chamber in front of the high-pressure cylinder on the quality parameters, so that the power model curve after parameter identification is more accurate than the actual load, and can make the The quality parameters are up to standard. The embodiment of the present invention also adopts the improved PSO intelligent optimization algorithm, so that the calculation precision is more accurate and the adaptability to the model is wider.
