Breadcrumb Home Var Speed/Fully Fed advantage of Modular Multilevel Converter Overview White paper 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 a Fully Fed topology work with a synchronous machine. The converter Electrification provides efficient and reliable converter equipment as well as the excitation system for synchronous machines. Our converter equipment is fulfilling all grid requirements e.g. LVRT/HVRT and harmonic contents, supporting the efficiency of your operations. Particularly for hydro applications, our variable speed solution provides additional flexibility to the grid, delivering 100% of pumping power adjustment. With our solution, existing Fixed PSPP can be revamped to variable speed applications. Electrification’s variable speed applications with a Fully Fed topology provide a power in pump mode variation and a higher dynamic power control, supporting and optimizing grid stabilization.
