Model and simulate complex thermodynamic cycle processes for electricity power generation using Clausius Rankine cycles

ClaRa Plus library enables the investigation of the transient behavior of Clausius-Rankine thermodynamic cycles, which are the basis all over the world for electricity generation from the most varied energy sources – from coal-fired power plants to direct steam generation solar power plants.

 Model Design Principles:

When setting up the model of a complex physical system such as a power plant, the first question to be answered is what physical fidelity is needed to cope with the given simulation task. The answer to this question refers to the level of detail necessary for each component and sub-process. The next step is to define the general physical effects to be considered for solving the given task. Finally, the level of physical insight into the considered physical aspects must be chosen.

Scope of the application of ClaRa Plus library:

• Coal fired power plants

• Gas turbine units

• Combined cycle power plants

• Heat recovery steam generators

• Cogeneration power plants

• Organic Rankine Cycles

• Grid emergency failures

• Island grid operation

Benefits

• Detect and avoid critical states in complex electric power plants

• Save time in modeling: Developed and validated in close cooperation with power plant engineering teams

• Optimize control models before real plant exists with precise analysis of process transients in components

• Fast and Efficient investigation of dynamic operation conditions, at component level, for their dimensioning

• Widens the scope of investigations

• Reduces modelling effort using predefined and preconfigured subsystem models

• Contain models at different level of details

• Separate SimCenter model is available which contains fundamental system definitions like ambient temperature and pressure or media to be used. It furthermore sums up interesting information of the cycle automatically

Highlights

• Modeling of steam Boilers with natural and forced circulation, gas or coal heated

• Modeling of Water-Steam cycles: pre-heating lines and components such as condensers and tanks

• Precise component models validated against reference and measured data

• Quickly design and dimensioning of components, such as containers, under dynamic operating conditions

• Development and evaluation of distributed control systems

• Ready-to-use subsystems, e.g. gas turbine unit models
