Figure 1 Simulation structure diagram for a turbine cold-end system.
approximated by the two fourth degree polynomial equations as follows:
The turbine "cold-and" system generally consists of turbine exhaust and condenser, and cooling tower
(Fig. 1). For a 250 MW unit, the turbine performance data with the maximum steam throttle flow can be

and
NHR = −45.19(CP)* + 420(CP)® – 1442(CP)2 + 2248(CP) +6666 (a)
NKW = 4,883(CP)* – 44,890(CP)3 + 152,600(CP)2 – 231,500(CP) + 383,400. (b)
The condenser and mechanical-draft cooling tower have the performance equations, respectively,

(The circulating water flow is assumed to flow at the rate of 145,000 gpm.)
In addition to the given performance equations give above, we also need two coupling equations to
complete the mathematical model for this cooling system. The first equation is the coupling between the…
