Application Of Network Thermodynamics To Analysis Of Thermodynamics System In Power Plant

For the characteristics of power plant thermal system,a network thermodynamic method was introduced to improve the existing thermal analysis methods.The method is based on the the similarity between thermal systems and electricity systems,and simulation of thermodynamics element with series-parallel form of electric network,which is composed of resistors,capacitors,inductors and other electrical components,and electricity network simulation software PSpice is used for analyze of the thermodynamics.The thesis discussed the application method of the network thermodynamics to thermal system in power plant,and exemplified the problems with Rankine cycle energy analysis,the main steam pressure - flow analysis.At last the feasibility of thermodynamic models of the Rankine cycle and the exergy loss calculation was verified by PSpice.Network thermodynamic method made thermal analysis easier and more universal,and there will be a good application prospects.
