Gas Turbine Applications using ThermoFluid

摘要: Abstract In a project between MathCore Engineering and Alstom POWER Sweden in Finspang Sweden, Modelica model of complete 43 MW gas turbine has been made. The main purpose this is to study transients under different working conditions. can be used optimize start-up sequence, simulate load rejections, verify design, test fuels etc. A new library called GasTurbine containing components specialized for modeling developed based on the existing public available ThermoFluid[1, 2] library. 1 Introduction paper issues, using ThermoFluid library, large industrial are addressed. GTX 100 from Sweden. This type producing power an external or internal electrical grid. fuel natural diesel oil. Testing such big turbines separate rig at each specific site costly time consuming. Transient tests might also lead performance degradation. detailed dynamic could hereby prevent possible problems before they occur real life. contains framework building thermodynamic applications as Modelica. previous projects build turbines[3, 4]. Combined with standard it connect other domains grid nets, motor, control systems, Unfortunately complex use even experienced user, familiar It does not contain blocks needed turbine. Therefore application made that more easy ready especially designed applications. current about components. There were mainly two objectives project. first objective was make reference static simulation tool IPSEpro[5]. suitable processes general added Complete models fleet frequently tuned correspond engine behavior. kind e.g. predict output given input data type, air temperature, ambient pressure, component target have steady state points identical result IPSEpro. done step by verifying calculation routines second rejection where outlet simulated disconnected instantly controller makes sure increasing rotational speed will limited. system implemented built up “real” engine.
