Predictive, adaptive model of PG 9171E gas turbine unit including control algorithms

摘要: Abstract Contemporary thermal diagnostic systems require computational tools, including mathematical models. Because of required short computation time, these models should have a simple structure. Therefore very often, for purposes, analytical-empirical are used. Such encompass both mass and energy balances additional empirical functions whose coefficients estimated by using the measurement results. As result, changing technical conditions taken into account. This paper presents simulation model PG 9171E gas turbine unit General Electric which contains partial an axial compressor, low-emission combustion chambers, expander. The unknown values were based on operating data least squares method. allows calculation non-measured parameters assessment indicators, e.g. efficiency electricity production. An important advantage developed is that it has capability adapting to machine. results calculations compared measurements. Model predictive quality was verified with use determination factor root mean square error.
