Power Watch India - - CONTENTS - BY SK Goyal and Monesh Sharma The au­thors (SK Goyal) are Gen­eral Man­ager-Me­chan­i­cal & CPP ser­vices at Cor­po­rate Tech­ni­cal and En­ergy Ser­vices and (Monesh) Man­ager-Me­chan­i­cal at Cor­po­rate Tech­ni­cal and En­ergy Ser­vices, Aditya Birla Group.

Ther­mo­dy­namic sim­u­la­tion mod­el­ling is proved to be one of the best meth­ods for the anal­y­sis of a cap­tive power plant. The case study men­tioned be­low gives an ex­am­ple of tur­bine per­for­mance anal­y­sis and pre­dic­tion of ther­mal en­ergy sav­ing by im­prove­ment in some critical pa­ram­e­ters like tur­bine in­let steam tem­per­a­ture and vac­uum.

Sim­u­la­tion mod­els can be very ef­fec­tive tools if we want to an­a­lyse ther­mal power plant sys­tems or pro­cesses. The fol­low­ing pic­ture shows the var­i­ous ar­eas where we can use the sim­u­la­tion method.

Sim­u­la­tion mod­el­ling is widely ap­plied for anal­y­sis and fore­cast. Such mod­els have al­ways been very use­ful in pro­vid­ing so­lu­tions re­lated to process en­ergy ef­fi­ciency and con­ser­va­tion.

Ben­e­fits of sim­u­la­tion mod­el­ling

Sim­u­la­tion mod­el­ling has the fol­low­ing ben­e­fits: 1. In­di­vid­ual per­for­mance of all critical com­po­nents of a power plant like boiler, tur­bine, con­denser, feed wa­ter heaters, etc. can be an­a­lysed. 2. Per­for­mance anal­y­sis of in­te­grated power plants hav­ing mul­ti­ple units of boil­ers and tur­bines can be car­ried out in min­i­mum pos­si­ble time. 3. Sim­u­la­tion mod­el­ling is very help­ful in power plants de­sign­ing and op­ti­mi­sa­tion projects. 4. What-if anal­y­sis can be done in a very ac­cu­rate and con­ve­nient way by sim­u­la­tion mod­el­ling. 5. Sim­u­la­tion mod­el­ling helps in un­der­stand­ing the ef­fect of process vari­a­tion on power plant in co­gen­er­a­tion sys­tem.

6. Per­for­mance can be pre­dicted if a new com­po­nent (for ex­am­ple HP heater) is added in power plant cy­cle.

7. Op­er­a­tion and main­te­nance plan­ning can be done ef­fec­tively and un­wanted forced out­ages can be avoided.

So sim­u­la­tion mod­els can be very ef­fec­tive tools to an­a­lyse ther­mal power plant per­for­mance and iden­tify im­prove­ment ar­eas.
