EBSILON ® Professional –The Planning Tool for thePower Plant ProcessEBSILON ® Professional is a simulation system for thermodynamic cycle processes that is used for plantplanning, design and optimization. Maximize the benefits of repowering and retrofitting measures bysimulating them in EBSILON ® Professional. Design a performance-optimized plant for your applicationscenario by introducing specific parameters into the model. Calculate the effects of component degradation,various load cases and changes in environmental conditions. Simulate the operation of newlydeveloped components in a cycle.2

Solution Algorithm – Fast & PowerfulEBSILON ® Professional highly efficient calculation kernelallows the detailed simulation of complex applications, likee.g. the district heating system of a city. The exceptionalspeed and convergence reliability of the algorithm ensure acorrect calculation of the cycle in the steady state. Release10 and higher offer the possibility of transient calculations.Convergence and controller diagrams as well as statisticalcharacteristics help to quantify and improve the convergencebehavior.● Fast simulation result: calculate a model with 1,100 componentsand 1,400 lines in only 2.5 seconds● Convergence analysis tools like convergence and controllerdiagrams● Twenty years of successful application and further development7

These include text fields and valuecrosses for displaying the results in the model as well as therepresentation of the processes in state diagrams.Export to MS Excel allows to further process the simulationresults easily.Value crosses and text fields in model● Value crosses, text and alarm fields in the model● Simulation reports in MS Excel● State diagrams: q,T; h,s; h, x i ; T,s; log(p),h● Convergence and controller diagrams● user defined diagrams in MS ExcelError Analysis andOnline HelpIntelligent error analysisDuring the simulation, modeling errors are localized by theintegrated error analysis, and the user is informed about theircauses.Online helpThe online help provides detailed information on the featuresof EBSILON ® Professional and the add-on modules. Thedesign and physical mode of operation of components areexplained to the user, and sample models are supplied.9

The Material Data Library –Working Fluids and FuelsThe material data library contains typical working fluidsand fuels of power plant and energy technology. Userspecificfluids can easily be defined by their chemicalcomposition. For coal, a detailed database for calorificvalues distinguished according to the extraction sites isintegrated.10

Fluids:● Water and steam● Brine● Humid air● REFPROP library (NIST): Ninety fluids from acetoneto xenon (two-phase)● Thermal oils and molten salts● Binary mixes:ammonia/water, lithium bromide/water● Ideal and real gases● Two-phase fluids● User-defined fluidsFuels:● Coal● Oil● Gas● user defined by composition11

EbsBoiler –the Boiler in DetailEbsBoiler contains components for the detailed modeling ofboiler geometry and heat transfer. Thus you map the boilerclose to reality, model specific boiler types, and determinethe degree of fouling of individual heating surfaces.Components of EbsBoiler:● Flue gas zone● Reaction zone● Main heating surface● Auxiliary heating surfaceEbsSolar –We Make the SunCalculableEbsSolar, developed in cooperation with the German AerospaceCenter (DLR), contains components for the detaileddimensioning of a solar field. It is suited for investigationsconcerning site and technology as well as for annual returncalculation.Regarding the simulation of the storage system, direct andindirect storage components are available. The indirect storagecalculates the temporally variable temperature field ofthe storage material. The direct storage allows the modellinge.g. of a two-tank liquid salt storage. Typical heat transferfluids like thermal oil, liquid salt, and water/steam are storedin the material data library.Components of EbsSolar:● Solar collector (parabolic trough/linear Fresnel type)● Distributing header● Collecting header● Heliostatfield● Solar tower (Receiver)12

OEM-GTLib –the Gas Turbine LibraryEbsOptimize –Plant OptimizationOEM-GTLib, developed in cooperation with and distributedby VTU Energy GmbH, contains a large number of gas turbinemodels. These are adjusted to the actual performancebehavior and are based on official manufacturer data. Thusyou select the optimal gas turbine for your power plant.Contains gas turbines from● Siemens● Alstom● General Electric● Rolls Royce● MAN● Solar Turbines● Hitachi● CentraxEbsOptimize optimizes a target value by varying severalinfluencing quantities. Thus the often laborious search for theoptimal performance parameters of the plant is automated.Optimize the efficiency or fuel consumption of the plant whilecomplying with all general technical requirements.● The target value and influencing quantities can be freelyformulated● Genetic algorithm● Available as an EbsScript function13

EbsValidate –Data ValidationEbsValidate adjusts the partially error-prone measured valuesof the numerous measuring points of your plant in such away that all component equations are complied with. At thesame time the error sum of squares is minimized. Theresult is the statistically most likely plant condition. Here theuse of redundant measured data increases the statisticalreliability of the validation result. Besides a quick validation,validation according to VDI 2048 is available, too.The offline validation with EbsValidate is suited● for supporting acceptance tests, and● for identifying malfunctions in the measuring system andthe components.EbsHTML –Plant Model in theWeb BrowserEbsHTML allows the output of the model including thesimulation results in HTML format. The results for componentsand lines are displayed in a tool tip when the cursor ismoved over them. Concerning the output you are free todecide which simulation results are to be displayed in theHTML file.● Will display in all common internet browsers● Various load cases and macros accessible● Suitable for presenting the plant model withoutEBSILON ® Professional license14
