The Rana Pratap Sagar Power Station (Rajasthan) with an installation of 4 units each of 43 MW operating under a head of about 50 m. is among the largest in India, from the view point of physical dimensions of the generating plant and equipment. It has presented some novel and intricate problems and its design and construction incorporate many interesting features—some of them introduced for the first time in India.
The Station came into operation at the beginning of this year (1968) with the commissioning of the first unit and the other units are being commissioned at short intervals. Situated in South-Eastern Rajasthan, this project is the second step in the Chambul Development which has been planned in the form of a cascade of three dams and a barrage for an almost complete utilisation of the river water resources in this area for both irrigation as well as power generation.
The present paper describes the basic factors in the planning of the Chambal cascade with special reference to Rana. Pratap Sagar and then discusses the salient electrical and, mechanical design features and some aspects of construction, planning and installation work. Part I of the paper deals with the planning of the project and layout and arrangement of main features. Part II will cover the details of main and auxiliary plant in the power house, control, system, station service systems, sivitch-yard and switchgear and construction programming and installation aspects.
