Beschreibung
Zusammenfassung:	The utility model relates to a cooling system for a steam turbine generator unit and a steam turbine generator unit system.The steam turbine generator unit comprises a steam turbine low-pressure cylinder and a water feeding pump steam turbine, and the cooling system comprises a cooling tower; the water feeding pump condenser comprises a first steam exhaust inlet, and the first steam exhaust inlet is used for being communicated with a steam exhaust port of the water feeding pump turbine; the peak condenser comprises a second steam exhaust inlet, and the second steam exhaust inlet is used for being communicated with a steam exhaust port of a turbine low-pressure cylinder; the cooling tower, the feed pump condenser and the peak condenser are connected in series through a cooling liquid pipe to form a closed cooling flow path. According to the cooling system for the steam turbine generator unit, the cost can be reduced, and meanwhile the pipeline arrangement difficulty is reduced. 本公开涉及一种用于汽轮发电机组的冷却系统和汽轮发电机组系统，该汽
