Modelica in Area of Thermodynamic and Energy Systems Applications with a Focus on ClaRa Library
Aleš Vojáček, Filip Ježek · Transactions on Electrical Engineering · 2020
The focus of this investigation is the development of an advanced transient model to describe the operation of a coal fired power plant which supplies electric power for a pyrometallurgy unit. Particular attention was paid to the effects of so called „downswings“ (cut-off the electric arc). The performance of the unit during such failures (accumulation of energy in steam boiler during fast transient of turbine power output) was investigated using a dynamic model. The modelling of the power plant was performed on the object-oriented, multi-domain modelling language Modelica and free ClaRa library.
