  • Penllergare (WAL) - Case Study

    A 40 ft LANDY Archimedes screw turbine has been installed next to the waterfall at Penllergare Valley Woods. This screw with a length of 11 m will generate power for the new visitor centre at the estate, while surplus will be fed to the national grid. The screw is featured by its high efficiency and fish friendliness. Capacity 2880 m3/h Location: Penllergare, Wales, UK ...

  • Wilhelminakanaal (NL) - Case Study

    Sluice III in the Wilhelminakanaal near Tilburg is equipped with a Landustrie hydropower screw pump. This means that the installation is used both to pump water and also to generate sustainable energy for approx. 200 households. The project is initiated by Rijkswaterstaat, part of the Dutch Ministry of Infrastructure and the Environment. Landustrie is responsible for the design of this innovative ...

  • River Dommel (NL) - Case Study

    In the spring of 2016 the construction of a new hydropower plant in the Dommel river near Sint-Michielsgestel started. The existing dam in the river is equipped with a Landustrie hydropower screw and will generate renewable energy for approximately 200 households. The Dommelstroom project is the first cooperative hydropower power plant in the Netherlands, initiated by Bram and Jan Taks, father ...

  • Windsor Castle (UK) - Case Study

    Early September 2011 two 40-ton Archimedes hydropower screw turbines were transported from Sneek, The Netherlands to the royal Windsor Castle, UK. Both screws are installed at Romney weir on the River Thames and power both the Royal Castle as well as 400 - 500 local households. The Landy screws dimension 4 meter diameter, 6 meter long and capacity 150 kW. Unique feature of each ...

  • VSC with a T-connected transformer-based electronic load controller for an isolated asynchronous generator feeding three-phase four-wire loads in a micro hydro system

    This paper deals with a novel solid state controller (NSSC) for isolated asynchronous generator (IAG) feeding three-phase four-wire loads driven by constant power prime movers, such as uncontrolled micro hydro turbines. AC capacitor banks are used to meet the reactive power requirement of the asynchronous generator. The proposed NSSC is realised using a set of IGBTs (insulated gate bipolar ...

  • Modelling of the hydro-generator local network operation and load disturbance rejection

    The paper describes models of the local network operation of the hydraulic turbine-generator unit. Two different models are proposed. They describe the dynamic behaviour of a system in which the unit is connected to an equivalent system. A nonlinear model of the interconnection to an equivalent power system is considered. An optimal controller for load disturbance rejection in water turbine speed ...
