This paper deals with the development of a small conveyor-type hydropower plant intended for operation in shallow river waters without construction dam. The proposed design offers closed-shaped flattened conveyor equipped flat-shaped blades. is oriented perpendicular to fluid flow. Several identical flat blades interacting flow are mounted on belt and move together one straight line direction. ...

Epileptic power supply in Nigeria has caused hindrances to her growth. Electricity is required for technological advancement and economic growth, as business transactions most activities depend on its availability. This work was aimed at developing a prototype hydropower plant use riverine area(s) electricity generation. Using Autodesk inventor software, the turbine designed thereafter fabricat...

California’s hydropower system is composed of high and low elevation power plants. There are more than 150 high-elevation power plants, at elevations above 1,000 feet (300 m). Most have modest reservoir storage capacities, but supply roughly 74% of California’s in-state hydropower. The expected shift of runoff peak from spring to winter due to climate warming, resulting in snowpack reduction an...

In an earlier paper (Kosnik, 2008), the potential for small scale hydropower to contribute to US renewable energy supplies, as well as reduce current carbon emissions, was investigated. It was discovered that thousands of viable sites capable of producing significant amounts of hydroelectric power were available throughout the United States. The primary objective of this paper is to determine t...

Electricity grid interconnections have played a key role in the history of electric power systems. The greatest benefits of interconnection are usually derived from synchronous AC operation, but this can also entail greater reliability risks. An alternative energy supply to assist the main power stations in future is expected from renewable energy sources based on distributed generation like Sm...

The modelling of electricity systems with substantial shares renewable resources, such as solar power, wind power and hydropower, requires datasets on resource profiles high spatiotemporal resolution to be made available the energy community. Whereas resources exist for diurnal seasonal scales across all continents, this is not yet case hydropower. Here, we present a newly developed open...

In order to study the stability and fast dynamic of the power grid, modeling and identification of hydropower plant systems such as turbine, governor and excitation is required. Turbine is a mechanical device and usually identified through field tests. In this paper, the identification of the unit 8 of Abbaspour power plant is conducted. The linear and nonlinear model of the Francis turbine are...

Renewable energy provides 20% of electricity generation worldwide. Hydroelectric power is the cheapest way to generate electricity today. It provides almost onefifth of the electricity in world. Hydropower is produced in more than 150 countries. The main objective of this paper is modelling and analysis of the effects of the power system stabilizer (PSS) for load frequency control (LFC) system ...

Estimation of total snow mass by means of SAR interferometry is problematic, due to high sensitivity of the interferometric phase to the snow water equivalent, leading to the phase unwrapping problem. In this paper, we pursue a recently proposed technique, delta-k interferometric phase estimation, that avoids phase wrapping by lowering the sensitivity of the interferometric phase to the snow wa...
