Power Electronics Applications to Hydropower Plants: Case Studies and Experimental Illustrations

By Prof. Thanga Raj Chelliah, Dept. of Water Resources Development and Management, IIT Roorkee

Abstract of talk:

Hydropower Plants (HP) convert the energy of water in the stream and river into electricity. The volume of water flow and the utilized head determine the quantity of electricity. The greater the flow and head, the more electricity is produced. Usually, hydro-turbines are optimized for an operating point defined by speed, head and discharge. HPs that are constructed at the beginning of the 20th century in the European continent were of fixed speed type employing synchronous machines and the same were continually established in Asian and American continents also. At fixed-speed operation, limited deviation from the water head and discharge are allowed if the efficiency of the turbine is considered as a constraint. Variable speed operation of hydro turbine and generator offers an attractive solution for improved efficiency at part-loads in addition to reduced draft tube pressure oscillations and greater flexibility in power delivery. This talk discusses recent trends, operational challenges and research opportunities on multi-megawatt power electronic converters fed large machine drives serving in hydropower plants with experimental results.
