The article presents a developed mathematical model of the control system of the con-
densing turbine PT-25/30-90/10M (PT-12/15-35/10M) for Kaluga Turbine Plant. This
turbine of active type has two adjustable (productive and heat extraction) and three non-
regulated volumes for regenerative heating feed water. The turbine is designed to drive a
synchronous electric generator of the TVS-30 type with the capacity of 30 MW and the
rate speed of 3000 min
–1
, as well as to supply heat consumers with steam from controlled
extraction. The dynamics of the turbine control system is described by a nonlinear system
of twelve differential equations. The analysis of the obtained models by computer numer-
ically solved differential equations and comparing the results with the experimental ones
confirmed the high degree of adequacy of the mathematical model.
Keywords:
steam turbine, control system, mathematical model, controlled steam extrac-
tion.
