GOVERNOR CONTROL APPARATUS

PURPOSE:To enable a control system to be formed with ease by a structure wherein discharge limitation is performed by suppressing a generator output step by step. CONSTITUTION:A contact point Y is switched on at timing of a working start and this state will be maintained for a fixed times. A generator output at this point of time is supplied to a discharge limiting value calculating section 10. The discharge limiting value calculating section 10 calculates a generator output at T times later on the basis of the inputted generator output, calculates a discharge limiting value PL according to the calculated value, and supplies the value PL to a discharge limiting value memory 11. A low-pass gate 13 selects one with a minimum value out of an output setting value PS, the discharge limiting value PL, and an authorized maximum output, and outputs the selected one as a reference value PS'. Further, a load limitation device ALR controls a load limiting electric motor 9 in accordance with the comparison result between the reference value PS' and an generator output PG. Furthermore, the contact point Y is switched on for every constant duration, and correspondingly the content of the discharge limiting value memory 11 is updated.
