1 ARHAM VEERAYATAN INSTITUTE OF ENGINEERING, TECHNOLOGY & RESEARCH Haripar (Mota Asambia), Bhuj Mandvi road, Mandvi Tal. Kutch (Gujarat) Date: 19/10/2016, Wednesday Duration: 1 Day A FEEDBACK REPORT ON VISIT TO SARDAR SAROVAR DAM, SURAT. Venue: Sardar Sarovar Narmada Nigam Ltd. Sardar Sarovar Narmada Hydroelectric Project, Department: Electrical Engineering Department No. of Students Present: 15 Faculty Guide: Mr Rakesh Bhadani Project at a Glance Main Dam - 1,210 m long, 163 m high from the deepest foundation level Designed Live Storage Capacity of the Reservoir 5860 MCM (4.75 million acre feet) Irrigation million Ha (1.8 million Hector in Gujarat benefitting 1 million farmers) Drinking Water villages and 131 towns (29 million people) Hydropower - 1,450 MW installed capacity (1 billion kwh every year) Canal Network - Approximately 75,000 km length within Gujarat The Narmada River It is the largest westward flowing river in India. It is starting from amarkantak rock which is situated near at Jabalpur in Madhya Pradesh. Its coverage area is Chhattisgarh, Madhya Pradesh and Gujarat. It is 1300k.m long and at last is meet to the Arabian Sea near Bharuch. Its branch river length is around 200k.m. There was many dams are constructed on the Narmada river. Like Bargi, Tawa, Narmada Sagar, Omkareshwar, Maheshwar and Sardar. 1

2 Introduction about Sardar sarovar Dam The Sardar Sarovar Dam is a gravity dam on the Narmada river near Navagam, Gujarat in India. It is the largest dam and part of the Narmada Valley Project, a large hydraulic engineering project involving the construction of a series of large irrigation and hydroelectric multi-purpose dams on the Narmada river. The project took form in 1979 as part of a development scheme to increase irrigation and produce hydroelectricity. 2

3 One of the 30 dams planned on river Narmada, Sardar Sarovar Dam (SSD) is the largest structure to be built. Following a number of controversial cases before the Supreme Court of India (1999, 2000, 2003), by 2014 the Narmada Control Authority had approved a series of changes in the final height and the associated displacement caused by the increased reservoir, from the original 80 m (260 ft) to a final 163 m (535 ft) from foundation. The project will irrigate more than 18,000 km 2 (6,900 sq mi), most of it in drought prone areas of Kutch and Saurashtra. The dam's main power plant houses six 200 MW Francis pump-turbines to generate electricity and include a pumped-storage capability. Additionally, a power plant on the intake for the main canal contains five 50 MW Kaplan turbine-generators. The total installed capacity of the power facilities is 1,450 MW. Its final configuration is the second largest concrete gravity dam after Grand Coulee Dam in the US and has the world's third largest spillway discharging capacity. Reservoir Full reservoir level: m.

The students acquired knowledge of the different electrical & other products. The students asked several questions and all the experts were happy to satisfy their queries. This visit was full of excitement and enthusiasm. 4

5 V. BENEFITS AND RECOMMENDATIONS The students found this industrial visit was very useful. This visit improved the students knowledge of various equipment that being used in hydro-electric power plant in India. Students were amazed at the speed at which the process occurred and how the automated systems could work according to the requirements. The students were expecting more visits like this one. 5
