Abstract

PURPOSE:To enhance the operating efficiency of a rotary electric machine by allowing an excessive maximum allowable current when it is within a predetermined time even if a field current exceeds the maximum allowable current and by containing the primary delay of the field current in a feedback loop. CONSTITUTION:When a deviation signal 7a between a field current 6a and the maximum allowable current 8a exceeds an allowable value V0, a time limiting circuit 17 is operated so that its contact 17a is opened. Thus, an integrator 15 will integrate the deviation signal 7a at a time constant responsive to the value of the deviation signal 7a. When the output signal from the integrator 15 exceeds the voltage of the signal 24a, time limiting circuits 25, 25' will operate to close contacts 25a, 25a' so that the deviation signal 7a is applied through a primary delay circuit 16 to an automatic voltage controller 3. In this manner, the operating efficiency of the generator 1 can be enhanced.
