Abstract :
The paper introduces an online performance test software for large capacity combined-cycle units. The software is composed of four parts, i.e. the integrated modular modeling software (IMMS), real time database software, client browser software and communication software. The results of the model are displayed in B/S mode on the userpsilas terminals. With IMMS, on-line performance calculating model is developed by means of modular modeling method, which follows the guidelines of ldquoPerformance Test Code on Overall Plant Performancerdquo (PTC46-1996). All the primary parameters used for model calculation are from DCS of the unit. The software has been successfully applied to a 395 MW combined-cycle power unit for a year. It runs stably and reliably. It can provide the economic indicator on line, such as gross equipment power output and gross equipment heat rate etc., so as to help operators monitoring and adjusting the operation of unit more efficiently.
