Abstract (en)

[origin: WO2007042732A1] The invention concerns an electromechanical system (1) designed to be connected to a power grid (7), comprising: an electrical machine (2) capable of operating as a stand-alone power generator, including a rotary shaft, and a switching system (9) enabling i) in a first configuration, the machine to operate as motor when the coupled device (4) is normally driven or as generator when the coupled device is normally driving, and ii) in a second configuration, the machine to operate as stand-alone generator, the electric power generated by the electrical machine (2; 22) being dissipated in the machine and in a dissipative load (13).
