Abstract

Die Erfindung betrifft ein Verfahren (10) zur Steigerung des Dampfmassenstroms einer Hochdruck-Dampfturbine (14) eines Dampfkraftwerks (10), insbesondere eines Dampfkraftwerks (10) mit Zwischenüberhitzung (38), während einer Hochfahr-Phase des Dampfkraftwerks (10), insbesondere auch während eines Leerlaufs des Dampfkraftwerks (10), bei dem einem Generator (20) des Dampfkraftwerks (10) vor einer Synchronisation mit einem Stromversorgungsnetz wenigstens ein elektrischer Verbraucher (46) zugeschaltet wird. Die Erfindung betrifft ferner ein Dampfkraftwerk (10), mit einem Generator (20), einer Hochdruck-Dampfturbine (14) und wenigstens einem elektrischen Verbraucher (46), der während einer Hochfahr-Phase des Dampfkraftwerks (10), insbesondere auch während eines Leerlaufs des Dampfkraftwerks, dem Generator (20) zugeschaltet werden kann, um vor einer Synchronisation des Generators (20) mit einem Stromversorgungsnetz einen Dampfmassenstrom der Hochdruck-Dampfturbine (14) zu erhöhen.

The invention relates to a method (10) for increasing the steam mass flow of a high-pressure steam turbine (14) of a steam power plant (10), in particular a steam power plant (10) with reheat (38), during a start-up phase of the steam power plant (10), in particular during idling of the steam power plant (10), in which a generator (20) of the steam power plant (10) before synchronization with a power supply network at least one electrical load (46) is switched on. The invention further relates to a steam power plant (10) with a generator (20), a high-pressure steam turbine (14) and at least one electrical load (46) during a start-up phase of the steam power plant (10), in particular during idling the steam power plant, the generator (20) can be switched to increase before a synchronization of the generator (20) with a power supply network, a steam mass flow of the high-pressure steam turbine (14).
