DAM Automation and flood control system
We are a leading Organisation working in the field of Canal Automation, Flood Forecasting, & Flood Routine, and other Automation System based on SCADA. We are the first in India to implement 100% Computerised Integrated System on Major Dams, where Canal Automation, Flood Forecasting, Flood Routing, and other Dam Activities like Water Supply Monitoring etc. are integrated. On line data of rain gauge, river gauge, lake levels, spillway gate positions, canal Head regulator and Cross regulators upstream, down stream canal levels in different reaches, water supply flow though pipe is collected directly at General control Center, using telemetry, where the collected data is analysed and appropriate instructions are given accordingly. In case of Flood Forecasting and Flood Routine, the On-line data received from Intelligent rain gauges, river gauges and lake levels is analyzed and quantum flood impinging to Reservoir and travel time is calculated and considering down stream storage constraints, capacity of Dam known quantum of flood with travel time, the radial gates are adjusted to release the water at moderate rate in advance to avoid any losses on down stream due to the flood. The releases are maintained in such a way, so that unnecessary releases are avoided & dam level is maintained at optimum. As the on line data is available at every 10 to 15 minutes interval, continuous adjustments are done.
Similarly in Canal Automation on line data of position of Head Regulator, Cross Regulator, Escape Gates, Outlets and Up Stream & Down Stream Canal Levels at different cross regulators in different reaches is collected at General Control Center, the water requirement as per FAO Standard is calculated at GCC and required water level is maintained to release the water by adjusting CR gates at different reaches, from GCC. Also a data at any cross regulator can be keyed as per the requirement of water releases and transmitted to GCC through telemetry network and GCC will take control actions accordingly. Also other activities at Dam site like Drainage Gallery Pumping Control, Isolated 24 V gallery lighting, Area Lighting, Water Supply releases, flow are controlled and monitored from GCC. We have also provided monitoring control center stations at different offices like Chief Engineers / Superintending Engineers Office, etc. at these places higher authorities is available to take the decision and control the activities. This system has helped authorities to regulate flood in adverse condition reliably and manage available water supply for irrigation with enhanced revenue.
