HRVS-DN Fills Irrigation Canals in India on Saradar Sarovar Sam

Product: HRVS-DN
Motor Ratings: 11kV, 140A
Sardar Sarovar Dam, India

Solcon's Medium Voltage HRVS-DN soft starter was selected to start reservoir water pumps as part of the Sardar Sarovar Dam project in Gujerat India (1210m length and 163m maximum height). The dam is the second largest in the world in terms of concrete volume (6.82 million m3) and third in the world in spillway discharge capacity (85,000 cumecs). The dam will irrigate 17,920 km2 of land spread over 12 districts (75% of which is drought-prone areas) in Gujarat and 730 km2 in the arid areas of Barmer and Jalore districts of Rajasthan.

As phase I of this tremendous project, 4 units of HRVS-DN (11kV, 140A) were supplied to Jyoti in 2012 and were recently commissioned by EMCO KIMO Solcon's partner in India. The units start the water pumps (rating 2.2MW) that fill the main irrigation canals from the reservoir. The current limit at the station is 320% and each start cycle runs between 20-25 seconds.

Solcon Industries has vast experience with Soft-start and Soft-stop for water applications around the world. The HRVS-DN features Pump Control that offers three (3) Voltage Ramp-down Curves as well as a Torque Curve allowing full customization of the pumps starting and stopping configuration based on the specific pump requirements. Using Pump Control prevents stall conditions and eliminates Water Hammer which can damage the pump as well as the pipe system.

Over the coming years Solcon is expected to supply at least 10 more HRVS-DN units as part of this project.
