I just ran your simulation and you are correct - there is a problem!  You have stumbled on a bug in the Type 591 source code.  If you have access to a FORTRAN compiler then I can show you the line to change in the Type 591 source code.  If not please let me know and we can send you an updated version of the TESS CHP Library - provided you are a licensed user of that library.

Dear Someone, 
 
I use the CHP library to develop a model for Rankine cycle power plant. I use the Type 591C to simulate the high pressure stage turbine firstly. This HP stage turbine has two extraction steam, with extraction pressure at 54.41 and 34.62 bar, and the inlet pressure and temperature of this turbine is 167 bar and 537 C. When I put the paramaters of this turbine as the input into the Input sheet of this module, there is a mistake when I run this module. It shows that
 "TRNSYS Message 127: The current Unit has tried to access an Input value higher than the number of outputs for the Type. Reported information: Not available". 
 
This is no mistakes for the paramapers of steam turbine. What's the problem of my model? The attachment is the model. 
 
Looking fordward for your feedback. 
 
Best Regards,
Jiyun Qin
