Excitation system for a synchronous machine |
摘要 |
An excitation system for a synchronous machine comprising an exciter having its output connected through a current relay in parallel with a starting-protecting unit. The starting-protecting unit includes parallel branches, each comprising a series-connected resistor and thyristor switch having a voltage-sensitive threshold element connected between its anode and gate. A turn-on unit for the parallel branches of the starting-protecting unit includes a voltage-sensitive overvoltage detector connected in parallel with the exciter output, in which the voltage setting is lower than that of the threshold element of the parallel branches of the starting-protecting unit. A memory unit; and a pulse-forming unit. The output of the overvoltage detector is connected through the memory unit to the input of the pulse-forming unit. The output of the pulse-forming unit is connected via the contacts of the current relay to the gates of the thyristor switches in the parallel branches of the starting-protecting unit.
