I used to enjoy spending hours sharpening by hand, but once life got busy, it turned into pure friction. I wanted a setup that stayed ready, made less mess, and delivered sharp edges fast—without the ...

Abstract: Large-scale variable-speed pumped storage motor-generator adopts rotor winding AC excitation technology, which can adapt to the regulation requirements of wide speed range and wide power ...

Abstract: This paper presents a mixed integer linear programming model for the hourly energy and secondary regulation reserve scheduling of a price-taker and closed-loop variable speed pumped-storage ...
