Design and off design pipe-network geothermal power plants analysis with power pipe

One of the biggest problems when analysing pipe network behaviour is the difficulty in accounting for the actual components features, as some conditions change in relation to the design one. This problem occurs, for example, when some power pmachines, like turbine or pumps, are connected to th epipes. In fact, for these devices, one flow rate corresponds to each pressure values and vice versa. For this reason, the pipe network operating points depend on both pipe geomtry and the physical behaviour of the other components. Furthermore, when hot and multi-component fluids are considered, thermal loss and composition calculation are required to cerrectly evaluate pipe behaviour. In the following, a simulation code developed by the author (Power Pipe) has been applied to a real geothermal power plant in which the wells can be considered as expanders, and the power unit is a steam turbine plant. Design and off design analyses have been performed by accounting for exergetic loss of the system components.
