The Simulation of Processes and Performances within Low Enthalpy Geothermal Power Plants

摘要

On the perspective of constant development, a major objective of today's international strategies - the exploitation of nonpolluting resources becomes a very important aspect. Geothermal energy represents one of the renewable energy resources. The exploitation of geothermal resources of low enthalpy with the aim of producing electric energy is a well extended direction of development. The paper is dedicated to the simulation of processes and performances within equipments which build up a GPP having as a destination the exploitation of low enthalpy geothermal deposits. After the short presentation of the actuality subject and the structure of GPP we pass on to the draft modules for the equipments from the GPP structure, with the aim of specific processes simulation. By using the programming medium Matlab/Simulink we apply the model for a GPP which will function according to pre-established conditions. The obtained result after simulation are verry good, and the most important parameter wich is followed is the efficiency of the plant. The results for this parameter is high for this type of power plants.
