i work in steam power plant now we will go to update the control system for the Turbine control system because there are alot of problem related to the spare parts for the modules and electronic parts.
the old system is from siemens to control 330MW steam turbine and as happened no spare part are availiable and should be replaced.
now we issue a bid to update the system and some company as ABB, Emerson and of course siemens are competed to win.
the problem is ABB and Emerson had some deviation :
1- required the geometrical and matrials parameters for TSE (turbine stress evaluators)configration.
2-for turbine stress calculation both contractor need some detailed information related to matrial dimension...... ETC.
for siemens every thing is ok because it has all of these data but its price is twice.
Thanks
