越流量調整装置および越流量調整方法

Japanese Patent JP7206916

B2

To provide an overflow adjusting device and an overflow adjusting method to suppress fluctuation of a water level generated at a downstream of a dam after the overflow of the dam occurs.SOLUTION: An overflow adjusting device is provided with: a dam water level detection part 401 detecting an overflowed water level of a dam 100; a dam water level determination part 402 determining the detected water level; a reducing water operation controller 403 performing a reducing water operation to control the water level of the dam 100 at a constant level; a guide channel water level detection part 404 detecting a water level of a guide channel 102 extending from a water inlet to an electric generator 103; a guide channel water level determination part 405 determining the detected water level; and a water inlet gate opening/closing control part 406 controlling opening/closing of the water inlet gate 601. The reducing water operation controller 403 starts the reducing water operation in a case that the water level detected by the dam water level detection part 401 is at a predetermined level. Then, the water inlet gate opening/closing control part 406 opens the water inlet gate 601 by a specific amount when a predetermined gap (amount) 604 exists between a water level detected by the guide channel water level detection part 404 and a water level for water consumption at a maximum output of the electric generator 103.SELECTED DRAWING: Figure 4
