The course is intended for participants without previous knowledge of EBSILON and provides a step-by-step introduction into creating an EBSILON model. The EBSILON component library and the various line types are discussed. Based on an error-free simulation of the design case of a simple Clausius-Rankine cycle, partial load calculations are examined for different load cases and environmental conditions (parameter studies). The gross and net efficiency of the circuit is determined with the help of efficiency meters. The functionality and applications of controllers are introduced. The cycle is supplemented by a furnace and an air/flue gas path. The turbine characteristic curve is determined (component identification) from the specification of generator output and live steam mass flow in various load cases. The Excel interface is used to export and import data. Finally, a detailed model of a steam circuit with reheating and regenerative preheating is created based on a template model. This model is used to display the results in the Ts diagram and QT diagram.

Based on manufacturer data, the user is introduced step by step into the modeling of multi-stage steam turbines. The correct parameterization of component 122 (steam turbine) and component123 (labyrinth seal) is explained on the basis of the real constructions and the technical-physical processes. The aim of this course is to enable the user to create a model that is as realistic as much as possible for calculating the entire load range in EBSILON^®Professional  using the few available data. Particular attention is paid to the parameterization of the comp.122 for the high pressure part and for the low pressure part. The partial load control with partial admission, fixed pressure and sliding pressure control is discussed and implemented. In the case of the low-pressure part, the current model concepts for taking into account the additional losses are dealt with, which result from the partial condensation of the steam during the expansion in the wet steam area and from the kinetic outlet losses. Based on a heat balance diagram a water/steam cycle is created using components 122 and 123, and the turbines are fitted to the results of the heat-balance diagram.

The course focuses on the modeling of combined cycle gas and steam turbine power plants (CCGT). The user is familiarized step by step with the construction of a combined cycle power plant, whereby the technical background of the individual construction steps is discussed. The aim of this training is to familiarize the user with the technical concepts and special features of a combined cycle power plant and to enable him to use EBSILON^®Professional  to evaluate them technically and to develop a good bases for an economic evaluation. The industry standard calculation of the gas turbine using correction curves is discussed. Particular attention is paid to the design of the water-steam cycle, whereby the individual measures to increase performance and efficiency are jointly developed and evaluated. Heat recovery boilers with one, two and three pressure stages are considered, and the various options for component specifications and alternative components for modeling the heat recovery boiler are discussed.

The course focuses on the modeling of steam turbine power plants with thermal heat extraction. The user is familiarized with the structure of a combined heat and power plant (CHP) step by step, with the technical background of the individual construction steps being discussed (special features of the design calculation and partial load behavior). The aim of this training course is to familiarize the user with the technical concepts and special features of heat extraction from a back-pressure and extraction condensation turbine. Control concepts for maintaining district heating output and flow temperature are presented. The calculations of key figures (degree of utilization and electricity loss figure) are discussed. Finally, special EBSILON components for the modeling of motor engines with heat recovery are discussed.

The course focuses on the modeling of solar power plants using parabolic trough technology. The user is introduced to the modeling of a parabolic trough power plant step by step, with the technical background of the individual construction steps being discussed. The aim of this training course is to familiarize the user with the technical concepts and special features of solar heat and electricity generation taking into account meteorological conditions. The user is made familiar with the time series calculation and the modeling of heat storage systems.

The course first introduces into using the actual "EbsScript" programming language. For this purpose, the syntax and the function library of EbsScript are discussed and simple EbsScripts are created. These EbsScripts are used to access the objects of a model and to carry out the simulation of the model.
In addition, the creation of user-defined "macros", which are wrappers around the functionality of existing Ebsilon components, are discussed.
With the help of "kernel scripting" user-defined components can be programmed, whereby it is necessary to program the complete physics of the component. Programming such kernel scripting is introduced using simple examples.
The EbsOpen interface, which is also part of the EbsScript license, allows to start the EBSILON application from another programming environment and to execute a simulation. A simple application will be created in Microsoft Visual Basic (or in Matlab or Python, depending on the preferences of the participants), which starts EBSILON and executes a simulation. The Excel add-in supplied together with EBSILON is also based on the EbsOpen interface, and a simple example is created in Excel to exchange data with EBSILON and simulate a model.
