Beschreibung
Zusammenfassung:	The invention relates to a method for operating a turbogenerator (1) comprising a turbine (3) and a generator (2) coupled to the turbine (3), wherein the generator (2) is designed to supply electricalthree-phase current or alternating current at a network frequency (NF) into a network, wherein the turbine (3) has a live steam valve (7) and an overload valve (8), said method comprising the following steps: monitoring the network frequency (NF) for a frequency drop (FA) in relation to a frequency setpoint value; detecting a status of the live steam valve (7) to check for an open state (ZU); andopening the overload valve (8) if a frequency drop (FA) is detected and if an open state (ZU) of the live steam valve (7) is detected. 本发明涉及一种用于运行涡轮机组(1)的方法，所述涡轮机组具有涡轮机(3)和与涡轮机(3)耦联的发电机(2)，其中发电机(2)构成用于将三相电流或交流电流以电网频率(NF)馈入到电网中，其中涡轮机(3)具有新鲜蒸汽阀(7)和过载阀(8)，所述方法具有如下步骤：监控电网频率(NF)是否存在相对于频率期望值的频率下降(FA)；检测新鲜蒸汽阀(7)的状态是否为打开状态(ZU)；以及根据检测到的频率下降(FA)和根据检测到的新鲜蒸汽阀(7)的打开状态(ZU)，打开过载阀(8)。
