GRAVITATION WATER VORTEX POWER PLANT
has a high efficiency and is an optimised turbine for the Gravitation Water Vortex Power Plant (GWVPP).
The Gravitation Water Vortex in the GWVPP concentrates the rotation energy without control devices or adjustable injectors to the Zotlöterer turbine. So the Zotlöterer turbine is a simple and robust turbine concept, which achieves a respectable efficiency at low head between 0,5 and 2m.
The characteristic efficiency of the Zotlöterer turbine at constant turbine speed in the GWVPP is similar to the characteristic efficiency of conventional regulated turbines. The total efficiency of a GWVPP depending on the turbine, the geometry of the rotation tank, the gear and the generator.
The nominal speed of the Zotlöterer turbine depends on the dimension of the GWVPP and at 15 to 40rpm is definitely lower than the speed of conventional turbines. Because of the low speed of the Zotlöterer turbine, the GWVPP has no risk of fish injury.
The rang of power generation is from 0,2 to 40kW. If the size of the investment does not matter, and there is enough volume available, it is also possible to install a GWVPP with 1MW or more electrical power.
In particular the free run of the Zotlöterer turbine at a sudden load rejection is very favourable, as at a load rejection the inflow to the GWVPP reduces automatically. So in contrast to conventional turbines the Zotlöterer turbine in combination with the generator, can operate in free run for a long time without any damage or rather can be easily connected to the power grid.
