Abstract: A pump-storage power plant, such as an electric unit, for this purpose can include a rotating electric synchronous machine and a frequency converter as well as a method for operating the electric unit. An exemplary method provides that the frequency converter is used to start the turbine and an output of the electric machine is fed directly into the current network after start-up, for example. Another exemplary method provides that the frequency converter is used to start the pump and the pump is started directly from rest and under load of a flooded pump or a water column, for example. Another exemplary method provides that the electric machine is synchronised with a frequency of the current network and is operated synchronously with the current network independent of the operating state of the pump or the turbine and supplies active power and reactive power.
Abstract translation: 用于此目的的诸如电气单元的储水电站可以包括旋转电同步电机和变频器以及用于操作电气单元的方法。 例如，示例性的方法提供变频器用于启动涡轮机，并且电机的输出例如在启动之后被直接馈送到当前网络中。 另一示例性方法提供了变频器用于起动泵，并且例如直接从淹没的泵或水柱的静止和负载下启动泵。 另一示例性方法规定，电机与当前网络的频率同步，并且与当前网络同步地操作，而与泵或涡轮机的运行状态无关，并提供有功功率和无功功率。
