Breadcrumb Home Var Speed/Doubly Fed Variable speed applications for pumped storage power plants (PSPP) allow a higher head range and therefore become a more economically viable option. Variable speed applications with AC excitation work with a doubly fed asynchronous machine. The conve Electrification provides reliable and efficient converter equipment for the AC excitation system. Our converter equipment is fulfilling all grid requirements e.g. LVRT/HVRT and harmonic contents and supports you to optimize your operations. Our Doubly Fed topology increases efficiency through speed optimization and supports grid control by providing a 30% power in pump mode variation. Particularly for hydro applications, Electrification’s system solution reduces turbine wear and provides higher dynamic power control, supporting and optimizing grid stability.
