<p>PURPOSE: To allow overexcitation to the tolerable limit which is set for securing the stability of the electric system even if overexcitation is generated repeatedly and at the same time, secure the stability of the electric system. CONSTITUTION: In this system, an integrator 11 which determines an integrated value for field current which is used as a reference for a tolerable value of overexcitation of a field winding 2, a storage 13 which stores the integrated value, judging from charging of a capacitor due to the output of the integrated value, etc., and an adder 14 which adds the integrated value which is obtained from the integrator 11 to the stored value are provided. When an added value of the adder 14 exceeds a preliminarily set limit value, a field control limiting means 16 is caused to limit the field control by ar automatic voltage regulator 4.</p> |
