The frequency converter can include at least two elements which can be used as inverters or as rectifiers according to the operating mode of the machine, for example during the operation of the motor or during the operation of the generator. The machine-side element can be provided within the cavern, and the network-side element can be provided outside of the cavern."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Electric unit for a pumped-storage power plant having components within and outside of an underground cavern","description":"A pumped-storage power plant, such as an electric unit can include a frequency converter and a rotating electric synchronous machine, the machine being provided in a cavern.
