転される。The upper diagram in Figure 2 shows fluctuations in the system frequency, and under normal conditions it fluctuates within the range indicated by the dashed line. The upper diagram in FIG. 3 shows fluctuations in the system voltage, which also fluctuates within the range within the dashed-dotted line during normal times. If the frequency and voltage of the grid are normal, they are detected to be normal at (42) and (45), respectively, and the switching devices (43) and (46) are activated by the reactive power setting device (41) and the load setting device, respectively. (1) side is connected. First, normal operation will be explained. ΔESM(
27) allows parallel operation with the grid even if the rotational speed changes by adjusting the secondary excitation frequency to match the grid frequency. Conventional water turbine generators have a constant rotation speed, so efficiency drops significantly when the load decreases, but by making the rotation speed variable depending on the load size, it is possible to reduce the drop in efficiency. As is well known, Therefore, the water turbine generator is started in the same way as the conventional model, and after being paralleled to the grid, the phase controller (50) is used to set the command values of +11 and (41) to the set load and set reactive power. 29), and the guide vane (5) is controlled by the speed governor (2) to operate at the maximum rotational speed.

1s (V(Iq+jld)) = 3VId (2), and it is well known that if Iq is controlled, P, that is, the power, can be controlled, and if Id is controlled, Q, that is, the reactive power can be controlled.

0) side. When the frequency is high, the water turbine generator absorbs power (the rotation increases to store energy, but parallel operation can be continued by controlling the phase of the cycloconverter),
That is, the electric motor is operated to suppress the frequency increase and return the frequency as shown by the dotted line. Conversely, when the frequency drops, the water turbine generator releases power (the water turbine generator decelerates), that is, performs power generation operation to suppress the frequency drop and stabilize the frequency as shown by the dotted line. The lower diagram in Figure 2 illustrates this situation. If left unattended, the system will go out of step as shown by the solid line and the system will collapse.

When the voltage is low, the water turbine generator is operated in a delayed manner, i.e., in strong excitation mode, to suppress the system voltage drop and pulled back as shown by the dotted line.On the other hand, when the voltage increases, the water turbine generator is operated in advance, in other words, in weak excitation mode. This suppresses the voltage rise and stabilizes the voltage as shown by the dotted line. The lower diagram in FIG. 3 illustrates this situation. If left as is, the system will collapse due to abnormal voltage as shown by the solid line.
