In certain areas of the earth there are geothermal fields where the area of land has a higher than normal thermal gradient, i.e. a much greater increase in temperature at depth. These areas are home to the high-temperature geothermal steam extraction wells that connect to the power plant via a network of pipes. These plants form a flexible energy system that can be adapted to daily demand conditions, since, despite the fact that their operation is strictly linked to the qualities of the environment where they are distributed (aquifers), through appropriate control and management of the resources, security of supply can be guaranteed at all times.
The operation and structure of geothermal power plants are based on the Rankine steam cycle, with the characteristic that there is no fuel burned in a boiler, since the steam is extracted directly, serving as a type of energy that can be considered renewable, since the geothermal steam is once again condensed and reinjected into the well after the turbine is turned. With adequate control of the extraction of steam from the subsoil, it is possible to contribute to the adaptation of supply to the daily demand profile, providing flexibility between generation and consumption.
You will be able to experience this flexibility of operation thanks to the simulation software PSV-GPP-SOF, with which you will test a multitude of generation situations, unravelling the operating principles of this type of power plant.
The PSV-GPP-SOF software has been designed by Edibon with the aim of showing the user the basic principles of operation of geothermal power plants, presenting in a didactic way the elements and parameters present in the generation process, as well as the interrelations between these parameters through the mathematical models integrated in the simulator.
The basic principle of geothermal power plants is the extraction of heat from the ground in the form of electrical energy to be fed into the grid. Thus, the application offers different levels of training that will provide the user with the essential knowledge and skills on the fundamental principles of operation and functioning of geothermal power plants, where this energy transformation takes place. In this way it will be possible to carry out a previous configuration of the operating conditions of the plant, to later carry out the control and management based on these factors.
