Start-Stop for Power Station Simulation - ClaRa 1.4.1 released
It sounds that easy: Simply switch of all pumps and heat sources to stop the output of a huge power plant. Which might already be non-trivial but daily business in real-life becomes literally a task of a life-time for simulation engineers. Almost any system simulation software struggles with thermo-hydraulic conditions at "close-to-zero-mass-flow" turning shut-off calculations into a never-ending odyssey. For sure not acceptable since on-off cycles have become a general procedure for many power plants.
A large part of the recently finished DynStart research project (expanding not less than 200 person months in total) funded by Federal Ministry for Economic Affairs and Energy on a decision by the German Bundestag was therefore dedicated to considerably enhance and speed-up "close-to-zero-mass-flow" simulations by taking all possible influences into account. The successful outcome and much more is now available to us with the latest release of ClaRa 1.4.1.
As always for free!
