In this case, if you try to control the generator or generator motor in parallel with the power system from the time of startup, the required capacity of the speed control device 8 will increase, which is impractical. The scope is defined. i.e. generator or generator 1! When starting an electric motor, it is initially disconnected from the power grid, and the rotation speed gradually increases.
It is customary to connect the generator or generator motor to the system only after the lower limit rotational speed at which variable speed control is possible is reached, and from that point on, the speed control circuit 7 performs speed control.

To explain this with reference to the drawings, Fig. 3 shows changes in the generator output P1 guide vane opening A1 rotational speed N and speed control gain G at the time of starting the variable speed hydroelectric power generation equipment. As is clear from this figure, first, the guide vane is gradually opened until the starting guide vane opening degree At is reached. When the rotational speed N gradually increases and approaches the lower limit rotational speed N1 at which variable speed control is possible, the guide vane is adjusted to a non-negative 61 opening degree A1.

(Function) In the method for starting the variable speed hydroelectric power generation equipment of the present invention configured as described above, since the control gain of the speed control circuit is small when the main engine is paralleled to the grid, the rotational speed of the main engine gradually increases. Then, the rotational speed target value N* is reached. Therefore, the torque required to suppress the increase in rotational speed, that is, the large output fluctuation, is not generated in the generator or generator motor.

In addition, after paralleling the main engines, when it is confirmed that the vibration caused by paralleling has subsided, such as after a predetermined period of time has elapsed, the control gain of the speed control circuit is changed to a second control gain that is larger than the previous control gain. Since the rotational speed is switched to the specified value, the ability to follow the rotational speed during steady operation is not impaired.

When the rotational speed N of the generator or generator motor 5 increases and approaches the lower limit rotational speed N1 at which variable speed control is possible, the guide vane 3 is adjusted to the no-load opening degree A1. At this time, the control gain G of the speed control circuit 7 is set to a small first set value Gl. If this first set value Gl is too large, the rotational speed N will be rapidly restricted, and if it is too small, the rotational speed N will rise above the upper limit rotational speed N2 at which variable speed control is possible. The rotational speed N is set to an intermediate value that can suppress the phenomenon, and therefore the rotational speed N changes without being restricted within a certain range.

Next, the generator or generator motor 5 is connected to the power system at time t1 when the rotational speed N further increases and reaches the lower limit rotational progress N1 at which variable speed control is possible, and thereafter, at a time when a predetermined period of time has elapsed. At t2, the control gain G of the speed control circuit 7 is switched to a second set value G2 which is larger than the first general constant value G1. This completes the starting operation.

As mentioned above, the rotational speed target value N* at the time tl when the generator or generator motor 5 is paralleled to the power system is set to the lower limit rotational speed N1. Since the set value G1 is set, the increase in the rotational speed N is not suppressed rapidly, but the rotational speed N changes gradually, and after some overshooting, stabilizes at the rotational speed target value N*. Therefore, the output P of the generator or generator motor 5 becomes flat as shown in FIG. 1, and the large pulse-like output fluctuation ΔP as in the case of FIG. 3 does not occur.

Further, since the value of the control gain G of the speed control circuit 7 is adjusted so as not to exceed the upper limit rotation speed N2, the rotation speed N

On the other hand, if the value of the control gain G is left as the small first set value Gl, the rotation speed N
However, in the present invention, the control gain G of the speed control circuit 7 is set to be lower than the first set value Gl at time t2 after a certain period of time has passed after the parallelization. Since the second setting [G2] is switched to the larger setting, the followability of the rotational speed N during steady operation is also improved.

In other words, the present invention provides control of the speed control circuit 7 during the moment when the generator or generator-motor is connected in parallel to the system, or immediately after, when various fluctuations, such as fluctuations in the rotational speed or fluctuations in the generator output, occur. The main purpose of this is to keep the control gain at a low value, so after connecting the generator or generator motor to the power grid, immediately reduce the speed after confirming that the fluctuations caused by the connection have subsided. The gain of the control circuit may be switched to the second set value G2.

As a method for confirming the end of the vibration during parallel entry, in addition to the elapsed time since parallel entry (t2-tl) described above, fluctuations in the generator output that occur during parallel entry (in the case of the present invention 1), (Sometimes the generator output fluctuates, albeit very slightly.)

Alternatively, as shown in FIG. 1, the condition may be that the rotational speed N becomes the lower limit rotational progress N1 again after overshooting during parallel entry. In this case, the rotational speed N may undershoot, so in practice it is necessary to simultaneously monitor the rotational speed fluctuation rate. Preferably, the condition is that the rate of change over time (d'N/dt) is within a predetermined range.

As described above, according to the present invention, when the variable speed hydroelectric power generation equipment is started and connected to the power grid, it is possible to suppress the occurrence of large output fluctuations, so that the power grid is not disturbed. The operation of the system becomes the product. Furthermore, since the rotational speed N can be made to follow the rotational speed target value N* in a relatively short time, it also contributes to improving the stability of the system.
