AN ELECTRIC POWER GENERATOR

摘要

The electric power generator comprises a rotor (100) being rotatable around a longitudinal centre axis (X-X) of rotation and comprising a rotor winding (111), and a stator (200) surrounding the rotor (100). The stator (200) comprises a stator core (210) with a stator winding (211) and a stator frame (220) surrounding the stator core (210). The generator comprises further a connection space (250) formed in connection with the stator frame (220), a fault ride through circuit (500) comprising a brake resistance (510) and a switch (520), the switch (520) being configured to by-pass the brake resistance (510) in normal operation and to connect the brake resistance (510) in series with the stator winding (211) in a fault ride through situation in order to consume electric power produced by the electric power generator (400) during a period of at least 250 ms required by grid code requirements so that the electric power generator (400) maintains its synchronism during this period of 250 ms. The fault ride through circuit (500) is positioned within the electric generator (400) between the connection space (250) of the electric generator (400) and the stator winding (211).
