Abstract

The embodiment of the invention provides a steam turbine adjusting system and method for introducing overshoot peak correction, and the system is additionally provided with an overshoot peak correction module and/or an initial step delay module on the basis of a classic one-time reheating condensing steam turbine adjusting system model for eliminating the influence of a generator side on turbine adjusting system model parameters and eliminating the influence of high-pressure cylinder front steam chamber volume delay on quality parameters, so that a power model curve obtained after parameter identification loads more actual conditions, and the quality parameters can reach the standard. The embodiment of the invention also adopts an improved PSO intelligent optimization algorithm, so that the calculation precision is more accurate, and the adaptability to the model is wider.

Description

technical field [0001] The invention relates to modeling of a steam turbine regulation system, in particular to a steam turbine regulation system and method which introduces overshoot peak correction. Background technique [0002] The existing intermediate reheat condensing steam turbine regulating system model is as follows: figure 1 As shown, there are mainly the following parameters: steam volume time constant T CH , reheater time constant T RH , the cross-tube time constant T CO , high pressure cylinder power ratio F HP , medium pressure cylinder power ratio F IP , low-pressure cylinder power ratio F LP , the natural overshoot coefficient λ of the high-pressure cylinder power. P GV Indicates the steam entering the turbine, P M Indicates the turbine power. [0003] In the course of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0004] At present, most of the simulation curves generated by th...
