Researcher in HydroFlex: Increasing the Value of Hydropower through Increased Flexibility
Faculty of Engineering
Department of Energy and Process Engineering
A three-year position as a researcher is available at the Department of Energy and Process Engineering, NTNU. The research will be conducted as a part of the HydroFlex-project which is a Research and Innovation action in Horizon2020. The research will be conducted in collaboration with HydroFlex-partners and the Norwegian Centre for Hydropower Technology (HydroCen). HydroFlex has 16 partners spread over 5 countries in Europe. The researcher will be responsible for the work package which has the objective to develop a variable speed Francis turbine that accommodates high ramping rates and 30 start-stops per day without significantly affecting the operating lifetime and efficiency.
A fundamental change for Francis turbine has been introduced by the variable speed operation through the converter. In addition, this turbine need to handle a lot more start stops and power ramping through its lifetime. Such operation will require the turbine to operate in unfavourable condition leading to high fatigue loads. In addition, the variable speed operation give large variation of the flow induced pressure fluctuation that results in a high risk for resonance in the turbine. To ensure that a Francis turbine can operate like this requires innovative actions.
The HydroFlex turbine design will be based on new design tools that ensure reliable operation. The Francis turbine will consist of the same parts as before, but the design process will have be more complex and CPU-demanding. A basic requirement of the development of new turbine technology is to understand the relation between the energy system parameters, number of start-stops, latency and ramping rate, and the design constraints expressed as mechanical fatigue loads. To improve the reliability and availability of Francis turbines, validated computational and experimental tools addressing the new operating conditions needs to be developed.
