電機２の見かけ上の出力特性となる。 Next, the operation will be explained. In Fig. 1, an excitation capacitor 3 is connected to the output windings 2a and 2b of the self-exciting induction generator 2, and a rotor (not shown) is connected to the output windings 2a and 2b of the self-exciting induction generator 2.
It is well known that when driven by the prime mover 1, the induction machine 2 causes a self-excitation phenomenon, induces voltage in the output windings 2a, 2b and the control winding 2c, and becomes an induction generator. When a load 4 is connected to the output windings 2a, 2b, the voltages of the output windings 2a, 2b change due to armature leakage reactance drop due to load current, armature reaction, and the like. Also, induction generator 2
Since the slip changes depending on the load, the output frequency also changes. Therefore, the automatic voltage regulator 8 detects the voltage of the output windings 2a and 2b, and gives a firing signal to the anti-parallel thyristor 5 in the series circuit connected to the control winding 2c so that the voltage is constant. By controlling the current flowing through the reactor 6 and resistor 7, not only the voltage is kept constant, but also the apparent load fluctuation of the induction generator 2 is reduced, thereby reducing the fluctuation of the output frequency. Figure 2 shows the output characteristics of the induction generator 2 as the load fluctuates when the output voltage is controlled to be constant . , P 2 is the power consumed by the series circuit of control winding 2c, P 3 is
This shows the sum of P 1 and P 2 and is the apparent output characteristic of the induction generator 2.

When the load 4 is connected to the output windings 2a and 2b, the apparent output characteristics of the induction generator 2 are as shown in the curve shown in Fig. 2.
P3 , the slip of the induction generator 2 increases by the amount of load variation, and as a result, the output frequency decreases. As shown in FIG. 4, when the rotational speed of the prime mover 1 remains at N1 and the load is changed from L1 to L2 , the output frequency decreases from F1 to F2 . In order to make the output frequency F 1 , the rotation speed of prime mover 1 must be
In other words, the output frequency is detected by the automatic frequency adjuster 11, a deviation signal S2 based on the deviation from the set value is input to the governor control device 9, and the output frequency is detected by the automatic frequency adjuster 11. By controlling the rotational speed of the prime mover 1 so as to eliminate the deviation, the output frequency can be kept constant despite load fluctuations.
