1. Mitigation of Pressure Pulsations in Axial turbine draft tube with jet injection or solid rod protrusion: A Numerical investigation
Sammanfattning : The introduction of intermittent renewable energy sources, such as wind and solar power, to the power grid, demands some hydraulic turbines to operate at unfavorable operating conditions not initially designed for. Strong swirl develops at loads below the best efficiency point, (BEP) due to angle mismatch between the guide vanes and the fixed runner blades typical for Francis and Propeller turbines. LÄS MER
Sammanfattning : Using renewable energy, such as water or wind, to produce electricity has been proven highly effective in Sweden. The ability of these renewable resources to make clean output energy counters the adversities caused by non-renewable resources. Amongst these, hydro turbines are one of the most preferred methods for generating electricity from water. LÄS MER
Sammanfattning : Hydroelectricity plays an important role to balance the stability of grid network. In order to improve the stability of presently high loaded grids, hydropower plants are being operated over a wide range of operations and experiencing frequent start-stop, load rejection, and load acceptance.
