用于运行抽水蓄能电站的电单元的方法
摘要：
本发明涉及抽水蓄能电站，尤其是抽水蓄能电站的电单元(1)包括旋转电同步电机(2)和频率变换器(3)以及用于运行电单元(1)的方法。本发明在此提供用于在抽水蓄能电站的电单元(1)的涡轮机运行中发动的方法。在此该方法规定，使用频率变换器(3)用于发动涡轮机并且电机器(2)的功率例如在发动之后立即输送到电网(6)中。此外提供用于抽水蓄能电站的电单元(1)的泵吸运行中发动的方法。该方法在此规定，使用用于发动泵(5)的频率变换器(3)并且直接从静止并且在例如注水的泵(5)或水柱的负载下发动泵(5)。此外提供用于运行抽水蓄能电站的电单元(1)的方法。在此该方法规定，电机器(2)与电网(6)的频率同步并且独立于泵(5)或涡轮机(4)的运行状态与电网(6)同步运行并且供应有功功率和无功功率。
摘要（英）：

The invention relates to a pump-storage power plant, particularly an electric unit (1), for this purpose comprising a rotating electric synchronous machine (2) and a frequency converter (3) as well as a method for operating the electric unit (1). The invention relates to a method for starting in turbine operation of the electric unit (1) for a pump-storage power plant. The method provides that the frequency converter (3) is used to start the turbine and output of the electric machine (2) is fed directly into the current network (6) after start-up, for example. The invention also relates to a method for starting in pump operation the electric unit (1) for a pump-storage power plant. The method provides that the frequency converter (3) is used to start the pump (5) and the pump (5) is started directly from rest and under load of a flooded pump (5) or a water column, for example.; The invention also relates to a method for operating the electric unit (1) for a pump-storage power plant. The method provides that the electric machine (2) is synchronised with a frequency of the current network (6) and is operated synchronously with the current network (6) independent of the operating state of the pump (5) or the turbine (4) and supplies active power and reactive power.
