Gilkes are the leading hydroelectric turbine manufacturer in the UK for projects up to 20MW
Made up of both Pelton and Turgo turbines the Gilkes compact range has been specifically designed and engineered for the sub 100kW market. Our simple case design coupled with precision-engineered runners and spear valves have produced a range of cost effective, highly reliable turbines suitable for a wide hydraulic duty.
As a keystone component in any hydro scheme, it is essential that the turbine is well maintained and protected from damage. All of our compact turbines are fitted with a failsafe to close deflector that will engage the jet in the event of load rejection preventing the turbine going into a condition known as over-speed.
Pelton turbines are medium to high head free jet impulse turbines. As an impulse turbine, the Pelton Turbine maintains high efficiency over a wide flow range. The jet strikes the splitter edge of the double bucket and is turned through an angle of nearly 180° before falling under gravity into the discharge channel or tailrace.
Originally designed and invented by Gilkes in 1919 the Turgo provides a simple and robust impulse turbine to operate on medium heads. The design allows a large jet of water to be directed towards the Turgo Runner at a high velocity.
The Turgo Runner extracts the energy from the water flow and imparts this energy to the turbine shaft. This mechanical power is then transferred into electric energy using a generator. The electric energy is then suitable to export to the national grid or to consume locally. With its ability to maintain a high efficiency over a wide flow range make the Turgo turbine an ideal solution for a run-of-river scheme.
Utilising our in house developed turbine controller, the Gilkes Compact Turbine Control System provides a fully automatic control system. Capable of controlling both grid connected and islanded installations with either induction or synchronous generators.
As standard, the Compact Control System includes:
Additional options available are:
The water turbine is the key to any hydro project and requires correct interfacing with the electrical, mechanical, hydraulic and civil aspects of the project. Gilkes has built on its experience over literally thousands of projects, this allows us to offer a truly integrated package of equipment. The optimum turbine selection for a given hydraulic duty and site application is dependent on many parameters.
