  • Generating system with fault detection
    Patent number: 4710840
    Abstract: "Doorbelling" in a generating system including a fault detecting circuit is prevented without the use of auxiliary power supply for a generator control unit. The generating system includes a permanent magnet generator (14) driving an exciter winding (18) and a relay (26) is utilized for interconnecting the two. Control of the relay (26) is exercised by a microcomputer (32) including a non-volatile memory (48) and programmed to remember the occurrence of a fault and thereafter prevent the relay (26) from cyclically opening and closing in response to power changes occurring as a result of connection and disconnection of the exciter winding (18) from the permanent magnet generator (14).
