4D4: Increasing Operational Flexibility of Francis Turbines at Low Head Sites, Through Analytical and Empirical Solutions
GE project to increase the operating range of low-head Francis units, i.e. Methods and approach to retrofit existing equipment in order to increase their flexibility to support 2030 decarbonization goals.
Standard Francis unit Plants can significantly increase their operating range by replacing the Francis runners with new runners of different designs. The presentation discusses recent retrofit results on such units.
