Abstract

PURPOSE:To stably make automatic control of a dam, by setting an aimed water level in stages and performing no gate opening and closing control against change in inflow within a certain range including measurement errors. CONSTITUTION:A calculation formula expressing an aimed water level curve set in stages is impressed upon an aimed water level calculating means 6 from an aimed water level curve generating means 5. The calculating means 6 calculates an aimed water level H from an inflow Q found by an inflow calculating means 4 on the basis of the calculation formula. From the aimed water level H found by the calculating means 6 and the current degree of opening or closing of a gate from a detecting means 2, an aimed outflow is calculated by means of an aimed outflow calculating means 7 and the degree of opening or closing of the gate corresponding to the aimed outflow is determined and opening or closing control of the gate is performed by means of a gate driving means 8 including a motor, etc. The detecting signal of the degree of opening or closing of the gate from the detecting means 2 is fed back and, when the inflow increases, the aimed water level becomes lower and the gate is opened. When the inflow decreases, the aimed water level becomes higher and the gate is closed.

At a dam installed on a river, when there is a large amount of inflow from upstream, the gate is opened to prevent the dam from overflowing and the water is released downstream, and when the amount of inflow is small, the water level does not drop. , the gate is closed, and conventionally,
In normal times, it was common to use constant water level control to maintain a constant water level or set flow rate control to control by setting the amount of outflow, and in floods to control the gate to be fully opened. Such gate opening/closing control is performed by a supervisor who observes the water level of the dam, the amount of precipitation, etc.

A method has also been proposed that automatically controls the opening and closing of gates by measuring the amount of water flowing into the dam. In this case, by measuring the water storage level and measuring the inflow amount from this storage water level and the outflow amount corresponding to the opening/closing degree of the gate, a target water level is determined according to the inflow amount, and the target water level is set. This system automatically controls the degree of opening and closing of the gate.

In the conventional method in which a guard operates the gate, it is difficult to perform appropriate control in response to sudden changes in the amount of inflow, and therefore requires sufficient experience on the part of the guard. Ta. In addition, in the conventional example of automatically controlling the opening and closing of the gate, the inflow amount is measured from the relationship between the outflow amount and the water level, and the water level is measured stably due to the influence of flowing water and waves caused by wind, etc. is not easy, and since the inflow is calculated based on the measured value of this water level, the measured value fluctuates even though the actual inflow does not change, and the target water level calculated from the inflow also fluctuates. do. This target water level lowers the target water level when the inflow increases, and increases the target water level when the inflow decreases, and has the disadvantage that hunting occurs in gate control due to fluctuations in the target water level.

Means for Solving Problem C] The dam control system of the present invention includes a means for measuring the amount of inflow into the dam based on the water storage level, etc., and a stepwise step-wise calculation of a target water level according to the amount of inflow by this measuring means. When the inflow increases, the gate is opened to lower the storage level, and the inflow is adjusted according to the target water level, which is set to change in stages. When the water level decreases, the gate is controlled to be closed to raise the water level.

As mentioned above, the target water level is determined in stages, so even if the inflow changes between Ql and Q2, the target water level will not change at Hl, so the target outflow will not change either. The gate will remain open or closed at that point. Therefore, gate control associated with unstable water level detection can be stabilized. In addition, when the inflow increases like Q1 to Q4 and becomes the flood inflow Q, the target water level is gradually lowered from Hl in the process, so the flood inflow Q
By the time the base water level HB has been reached, the flood inflow ilQ
The dam can also be controlled to prevent it from collapsing. On the other hand, when the flood inflow amount Q gradually decreases to the normal inflow amount, the target water level is gradually increased from the base water level HB.

FIG. 4 shows a relationship curve between the inflow amount and the target water level in another embodiment of the present invention, and shows the process by which the target water level is changed in stages.
It is designed to be a continuous change. Thereby,
When the inflow rate increases from Q2 to Q3, the target water level does not suddenly change from Hl to H2, but becomes H3 between them. That is, the target water level is set as a zone in which the target water level does not change within the range of the inflow amount, and the target water level is continuously changed between the zone. As a result, in the process of changing the target water level, the target water level changes gradually according to the inflow amount, and sudden changes in the target water level do not occur. Gate opening/closing control is also performed gradually, ensuring smooth control. It is something that can be done.

FIG. 5 shows a relationship curve of an embodiment in which the target water level is set within the range of the inflow amount and is set in stages. When the inflow amount is Ql, the target water level is Hl, H2. If the inflow rate increases to Q2, the target water level remains unchanged at 4. Also, when the inflow rate increases to Q3, the target water level is set within the range from H1 to H3,
When the water level increases to Q4, the target water level is set within the range from H2 to H3. Therefore, if the target water level is set to H2, it will not change even if the inflow rate changes from Q1 to Q4, and if the target water level is set to Hl, the inflow rate will not change from Q3 to Q4. When the target water level increases to H2
It will be set within the range of ~H3. Also, when the inflow increases, the target water level is set along the lower curve of the target water level curve, and when the inflow decreases, the target water level is set along the upper curve. It is also possible to give a hysteresis characteristic to the setting.

By providing such a setting width of the target water level, the width of the fuwazai will vary depending on the setting value of the target water level, and it becomes possible to set the target water level corresponding to various conditions. Also, depending on whether the change in the inflow rate is rapid or gradual, it can be determined whether to select the upper limit, the lower limit, or the intermediate value within the set range.

The target water level can be set within a range, and changes in the target water level that are set in stages can be made smooth.

[Effects of the Invention] As explained above, the present invention has a means including an inflow amount calculation means 4 etc. that measures the amount of inflow into the dam based on the water level etc., and a stepwise target set according to the amount of inflow by this means. When the inflow rate increases, the target water level is lowered step by step, so the gate is controlled to open in accordance with the target water level, and When the inflow rate decreases by 1, the target water level increases step by step, so the gate is controlled to close in accordance with the target water level.By setting the target water level in steps, the target water level increases in stages. Since a dead zone is formed at the target water level, there is an advantage that stable gate opening/closing control can be performed against fluctuations in the measured inflow amount.

It is equipped with means for measuring the amount of inflow into the dam, and means for determining a target water level in stages according to the amount of inflow by the means, and when the amount of inflow increases, the storage water level is adjusted according to the target water level by the means. A dam control method that opens the gate to lower the water level, and when the water level decreases, closes the gate to raise the water level.
