Gravitational water vortex hydraulic turbine implementation in Colombia: hydropower potential and prospects

Anti-vortex structures at hydropower dams

Vortex formation due to power generation at hydropower dams could cause serious problems, and eliminating or reduction in its strength is one of the dam designer and manager duties. Therefore, the design and use of anti-vortex structures is usual. Design of an anti-vortex structure for each project is unique and it is therefore necessary to have knowledge about the performance of each one. In t...

Influence of the Vortex Rope Location of a Francis Turbine on the Hydraulic System Stability

Hydroelectric power plants are known for their ability to cover variations of the consumption in electrical power networks. In order to follow this changing demand, hydraulic machines are subject to off-design operation. In that case, the swirling flow leaving the runner of a Francis turbine may act under given conditions as an excitation source for the whole hydraulic system. In high load oper...

Hydraulic turbine governing system identification using T-S fuzzy model optimized by chaotic gravitational search algorithm

Hydraulic turbine governing system (HTGS) is a complicated nonlinear system that controls the frequency and power output of hydroelectric generating unit (HGU). The modeling of HTGS is an important and difficult task, because some components, like hydraulic turbine and governor actuator, are with strong nonlinearity. In this paper, a novel Takagi–Sugeno (T–S) fuzzy model identification method b...

Prospects and Challenges of Small Hydropower Development in Jordan

Jordan‟s energy balance is largely dominated by combustible fuels. However, the country is well endowed with solar, wind and oil shale resources, in addition to large and small-scale hydropower projects. Based on available data and the current analysis, it is believed that there are at least 6-10 candidate sites in the western part of Jordan and 2-3 locations in the eastern plateau, which could...
