On condenser mathematical model method introduction into steam turbine unit mathematical model

The paper presents the method of introduction of the condenser mathematical model into the mathematical model of the steam turbine unit. The method is illustrated by the block diagram. The authors show the interaction of the turbine and the condenser by the example of the turbine T-50-130. It is shown that the magnitude enthalpy difference of the exhaust steam and the condensate is not constant and depends on many factors which can be considered only within the combined model of the condenser and the steam turbine unit. The authors show the dependencies in order to determine this magnitude for the turbine T-50-130 when operating in heating and condensing modes. They give equations of the condenser material and energy balance on the basis of which it is possible to calculate the condenser heat load taking into account all the components entering into the heat flow which substantially exceeds the calculated magnitude of the manufacturers.
