<p>PURPOSE:To regulate a disturbance of the line power for switching, by holding a stabilizing operation of the power line for a certain period when an exciting controller is switched from an automatic voltage regulation to a manual voltage control. CONSTITUTION:A stabilizing device of the power line 2 supplies the stabilizing signal of power line in order to regulate a voltage disturbance from active power of the generator. And a deviation amplifier 8 supplies the output which is given by adding a voltage detecting signal, a reference signal and the stabilizing signal of power line to a pulse generator 11 of the exciting thyristor 12. On the other hand, the output of manual voltage setting device 16 is supplied to the pulse generator 11 by opening a contact 9 on manual operation. By closing a one-pulse contact 17 for a certain time together with the opening of the contact 9, consequently the power disturbance can be regulated during the switching over periods.</p> |
