Beschreibung
Zusammenfassung:	The invention achieves an increase in the net electric power supplied to the mains network by solar thermal power stations with cylindrical parabolic collectors, by making efficient use of the solar field, generating steam to drive the main auxiliaries by steam turbines (turbo pumps), reducing the electricity consumption of the auxiliary services and increasing the net electric power. On days when the solar radiation is greater than that for which the system was designed, part of the solar field will not be used because the generator and the turbine would exceed the power level assigned to them. The proposed system uses the unused portion of the solar field to generate steam to drive the main auxiliaries of the power station, energy that would otherwise not be utilized. In addition, the pumps of auxiliary services are driven more efficiently overall when use is made of steam to drive the pumps via a turbo pump instead of driving them with electric motors (motor pumps).
