【発明の詳細な説明】 本発明は水力発電所における放流水位制御装置に関する

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a discharge water level control device in a hydroelectric power plant.

一般に水力発電所は一つの河川の上流より取水 。Hydroelectric power plants generally take water from upstream of a single river.

However, depending on the construction site, the water used for power generation or bypass water may be discharged into another river as shown in Figure 1. . In Fig. 1, Li is a river that takes water to the power station PS, and L2 is a river that discharges used water or bypassed water from the power station. WT1 to WT3 are water turbines. By the way, when the river L2 into which water is discharged is small, the rise in the water level of the river due to the discharge may greatly exceed the water level rise rate (for example, 30 cm/30 min) set for that river.

For this reason, they may cause disaster to people working in rivers and fishing. Therefore, in such cases, a discharge regulating device is generally provided to adjust the amount of discharged water so that the rise in the water level of the river into which the water is discharged does not exceed a predetermined water level rise rate. The discharge adjustment device has n9 preset discharge water volume setters and a discharge water quantity selection circuit that selects them, and according to the discharge water quantity selected by the discharge water quantity selection command, the flow rate adjustment valve of the water turbine (for example, a Francis turbine) guide vane)
Or it controls the bypass gate. 5 The rate of rise in the water level of a river due to discharge will be different when the river is small and the cross-sectional shape of the river is an inverted trapezoid as shown in Figure 2, when the natural flow rate Qn is low as in Figure 2 A, and when the natural flow rate Qn is low as in Figure 2 Old. A difference occurs when the natural flow rate Q'n is large.

In other words, for the same discharge amount Qg, the water level rise width H when the natural flow rate is small is greater than the water level rise width H' when the natural flow rate is large.
Become bigger. From this, in order to maintain the water level rise rate at a predetermined value, when the natural flow rate of the river is low, that is, when the water level of the river is low, the amount of discharged water must be reduced.
In other words, if the natural flow rate is large, that is, if the water level of the river is high, it is better to increase the amount of water released. Therefore, it is conceivable to measure the river water level and use this as the discharge water amount selection command. However, in this case, water is released according to the river water level due to natural flow, so the water level in the river changes from moment to moment as the amount of water released is added to the natural flow of the river.

Then, the opening degree (for example, the flow rate adjustment valve opening degree of the water turbine or the bypass 5 valve opening degree) must be continuously controlled by the discharge regulating device in response to this water level change. Generally, the river into which water is discharged is located far away from the power plant PS, so it takes a considerable amount of time for the water to flow down. Therefore,
This is a problem because it is very difficult to incorporate this time delay into the control system, which reduces reliability.

An object of the present invention is to provide a discharge water level control device for issuing a discharge water amount selection command for operating a discharge regulating device reliably and safely. In order to achieve this purpose, in the present invention, several river water levels are determined in advance for the amount of discharged water judged from the shape of the river moon, the river water level immediately before the discharge is started is read and stored, and Ensure that the amount of water discharged is constant from beginning to end.

By doing this, there is no need to consider time delays, and the rate of change in water level due to discharge becomes smaller as the water level rises because the amount of discharged water is constant. becomes possible. Examples thereof will be described below.

It is assumed that the water level of the river to be discharged is greater than or equal to the setting value L of the setting device S, and less than or equal to the setting value L2 of the setting device S2. In this state, as shown in FIG. 6, relay RYl operates, and relays RY2 and RYn are inoperative. The operation of relay RY closes contact RYl-a, and the operation of auxiliary relay RYlX closes its contact RYlX-a. On the other hand, relay R

YnY doesn't work either. In this case, the contacts RYlY-B, R
Since both Y2Y-B and RYnY-b are closed, when the discharge regulator DIS is in use and the contact STP-a is closed as described above, the out-of-setting low water level determination relay RY is activated.
OY works. By the operation of this relay RYOY, a discharge water amount selection command (contact RYOY-

Then, the contacts RYlX-A, RY2X-B, RYn
Since X-b1 is closed, the water level storage relay RYlY operates and stores that the Kawazuki water level is within the range of L1 and L2. When this memorization is completed, i.e. after a certain time limit (approximately 1
sec) Contact STR-a is opened. Water level memory relay R
When Y and Y operate and it is memorized that the river water level at that time is in the range of L1 and L2, the contact STP-b is open, so the water level memory relay RYlY is activated until the contact STP-b is closed. Retain that memory. On the other hand, due to the operation of the water level memory relay RYlY, the water level L

When water is discharged in this manner by a discharge regulating device (a guide vane of a water turbine, a bypass valve, a dam gate, etc.), the water level of the discharged river gradually rises.

When the water level reaches the set value L2 of the water level setter S2 or higher, and further reaches the set value Ln of the setter Sn, the auxiliary relay RY2X and then the auxiliary relay RYnX operate. However, since the activation operation of the discharge regulating device DIS has been completed, the contact STR-a will not close again. Therefore, as long as the water level memory relay RYlY is in operation,
Since the other water level memory relays RY2Y and RYnY do not operate, the discharge amount is kept constant. Then, when the need for water discharge is eliminated and the use of the water discharge adjustment device is excluded, the contact STP-b is restored or closed, and the water level storage relay RYlY is restored. Next, the discharge adjustment device DI
Consider a case where the river water level before S operates is greater than or equal to the set value L2 of the water level setter S2 and less than or equal to the set value Ln of the water level setter Sn.

In this state, both auxiliary relays RYlX and RY2X operate before contact STR-a closes, so contact RY
2X-b locks the operation of the water level memory relay RYlY. Then, the water level memory relay RY2Y operates and gives a selection command (contact RY2Y-a) to the discharge adjustment device DIS. In addition, when the river water level before the discharge adjustment device DIS operates is equal to or higher than the set value Ln of the water level setting device Sn, the water level memory relay RYnY similarly operates, and the discharge corresponding to the selection command (contact RYnY-a) is activated. The amount of water. The operating ranges of the water level memory relays RYlY, RY2Y, RYnY and the out-of-set low water level discrimination relay RYOY are shown at the beginning of FIG. Although the above description is an example using a relay circuit, it goes without saying that the object of the present invention can also be achieved using a semiconductor logic sequence and programmable means.

For example, in the case of a semiconductor logic sequence, a flip-flop circuit would be used in place of the water level storage relays RYlY-RYnY. As described above, according to the present invention, the water level immediately before the start of water discharge is read, it is memorized, and a command is given to the water discharge adjustment device to discharge a constant amount of water from beginning to end with respect to that water level. , there is no need to consider the water flow time.

In addition, the water level change due to discharge is because the amount of discharged water is constant.
As the water level rises, it becomes smaller, and water can always be discharged at a rate below a predetermined water level rise rate. In other words, the control reliability of the discharge regulating device is greatly improved.
