First results from testing of a software system for diagnosis of the operation, economy and operational state of steam power plants

Abstract

Despite the long operating experience with the steam power units in Serbian power system (some of them are at the end or even passed their planned working lives), unfortunately there is a lack of data for their operating regimes, the process parameters and the performance deviations, the economy and operational states for the previous period. These data would not only be useful for the optimal process control but also for the planning of maintenance and service agreements, retrofits and repowering of power plants. For these reasons and the others, also important, the software system for the diagnosis of operating conditions, economy and operational states of different components is being developed for the referential steam power unit. A better control of the process and operational state, thanks to the use of the results obtained with this software system, will bring lasting benefit to the efficiency and economy increase. Furthermore, it enables an increase of reliability and availability of steam turbine units and makes their working life longer.
