    • Adaptively Learned Modeling for a Digital Twin of Hydropower Turbines with Application to a Pilot Testing System 

      Wang, Hong; Ou, Shiqi; Dahlhaug, Ole Gunnar; Storli, Pål-Tore Selbo; Skjelbred, Hans Ivar; Vilberg, Ingrid Kristine (Peer reviewed; Journal article, 2023)
      In the development of a digital twin (DT) for hydropower turbines, dynamic modeling of the system (e.g., penstock, turbine, speed control) is crucial, along with all the necessary data interface, virtualization, and dashboard ...

    • Airbag for piping systems 

      Vilberg, Ingrid Kristine (Master thesis, 2010)
      Pressure transients are caused by a change in the volumetric flow in a pipeline system, and can have severe consequences for rapid changes of the volumetric flow. A sudden closure of a valve is a common source of a pressure ...

    • Study of cavitation, pressure pulsations and flow control methods in hydro power plants 

      Vilberg, Ingrid Kristine (Doctoral theses at NTNU;2019:30, Doctoral thesis, 2019)
      Hydro power plants play an important role in balancing power supply and maintaining a constant grid frequency. With the large water storage capacity, hydro power is in a favourable position with regard to operational ...
