Abstract

PURPOSE:To prevent the malfunction of the dam control system by giving the periodical check to the gate opening and then locking the gate control part in case the variation amount of the gate opening exceeds continuously and twice the set value. CONSTITUTION:Outflow amount calculation part 4 calculates the outflow amount based on the gate opening and the data given from water level indicator 2; inflow amount calculation part 5 calculates the inflow amount based on the outflow amount and the water level change; and target discharge amount calculation part 6 calculates the target discharge amount based on the target water level and the inflow amount respectively. Based on the target discharge amount, the target opening of the gate is calculated at gate opening calculation part 7. Then gate 23 is operated via gate operation command part 8 and gate control unit 9. In such system of the fault detection, the output of gate opening meter 1 is sent to opening data comparison calculation part 3. And in case the opening deviation to the previous value exceeds continuously and twice the set value, alarm transmission device 11 displays the fault. At the same time, gate 23 is locked via gate control lock part 10.
