Protection of pumped storage power plants using vacuum

IntroductionCase StudyApplication of Vacuum Generator Circuit BreakerConclusionReferencesPSPP have been and still are one of the most efficient ways to store energy on the giga watt hour scale. The increasing share of renewable energies creates new challenges in terms of system operation and equipment design. The unstable behavior of renewable and non dispatchable sources necessitates installing pumped storage stations in such networks which is one of proven solutions for the grid reliability. Several ways of launching the synchronous motor are: 1. Direct energizing from the gridwhich however creates brutal mechanical stresses on rotor and leads to quick ageing. This method is no longer preferred. 2. Methods using Static Frequency Converters (SFC)are considered as soft starts as motor is started slowly by varying frequency. 3. Back to back accelerationis used when the SFC is not available. Here one of the machines is accelerated with excitation using the hydro turbine. It provides electrical power with an increasing frequency to accelerate another machine as a synchrono...Get price
