Rajghat Canal Project

Background:

The Canal network comprising of 400 Km. main canal and 600 Km Distributaries and Minors irrigating the command area of about 100000 ha is monitored from single control room using the system.

The catchment area of 50000Sq. Kms upstream of Rajghat Dam is being monitored using this system. The farthest station in the communication network is located about 450 Kms from Master Station and about 600 Km between farthest stations.

Manual mode of operations has following limitations:

During the rainy season the weather conditions at the dam site are adverse. Fogs, high humidity, inaccessibly are some of the reasons.

Maintaining control manually for a long time is very rigorous, tedious, making the job very difficult. 

Negligence of person on duty can create serious situation during heavy rainfall periods.

The dam sites and canal sites are remotely located, operators stationed at these sites required to take many readings like, lake levels, canal levels, canal flows, gate positions manually.

In adverse conditions, operator is likely to make mistakes. Depending on these readings he has to refer many charts to calculate various control parameters.

To minimize the limitations Canal Automation was a necessity

Major Components of the System

Development of GIS based software for water resource management for Dam & canal.

Remote Canal field stations operating on solar power, communicating to the Master Station over VHF data communication network through local SCADA stations.

Remote Rain gauge stations operating on solar power, communication to the Master Station over VHF data communication network through repeater stations.

Remote River gauge stations operating on solar power communicating to the Master Station over VHF data Communication network through repeater stations.

Weather station for monitoring Rainfall, Wind Direction, Wind Velocity and Temperature & Relative Humidity interfaced with the SCADA System.

SCADA stations for local data collection and transmitting the data to Master station over VHF data communication link.

Master Station for Data Storage and Analysis.

Voice communication network for point-to-point communication with master, SCADA and field stations.

GIS based SCADA software for local monitoring and Central Monitoring with Database Management software on server.

Repeater Stations have established for smooth data and voice communication operating on solar power.
