REDAWN – Reducing Energy Dependency in Atlantic Area Water Networks

P.I.: prof. Helena Ramos (IST coordinator)

Collaboration of Prof. Paulo Branco and Prof. João Fernandes

Funded by Interreg Program, EU

Objectives:
  • Completion of an energy recovery resource assessment in water networks in the Atlantic Area;
  • Completion of an economic/environmental impact assessment of this technology on the region;
  • Development of design guidelines and support tools for hydropower energy recovery in drinking water, waste-water, irrigation and process industry sectors;
  • Development of policy and institutional support tools to increase the implementation of energy recovery projects;
  • Quantification of the societal impacts of hydropower energy recovery in water networks, and;
  • Widespread dissemination and promotion of energy efficiency in Atlantic Area water networks.
  • Works developed by this team:

    Electric behavior of the Pump working as Turbine (PAT) in off grid operation

    Optimal energy efficiency of isolated PAT systems by SEIG excitation tunning

    add1

    This work proposed a solution that uses a bank of capacitors coupled to a self-excited induction generator to regulate the operation of the pump as turbine.

    add2

    To improve the efficiency in these recovery systems for rural areas, a methodology to obtain the best efficiency of the PAT-SEIG system is proposed,  when operating under different speeds and loads.
