  • Forecasting monthly energy production of small hydropower plants in ungauged basins using grey model and improved seasonal index

    A first-order one-variable grey model (GM(1,1)) is combined with improved seasonal index (ISI) to forecast monthly energy production for small hydropower plants (SHPs) in an ungauged basin, in which the ISI is used to weaken the seasonality of input data for the GM(1,1) model. The ISI is calculated by a hybrid model combining K-means clustering technique and ratio-to-moving-average method, ...

  • Understanding water-society nexus: insights from Turkey's small-scale hydropower policy

    Turkey's recent venture involving the construction of hundreds of small-scale hydropower projects is a significant trend, both in regard to its contribution to Turkey's hydroelectricity production and the social and environmental impact of these projects at the local level. Turkey's hydropower policy was premised on a conventional understanding of water driven by science, technology, and the ...

  • A small island in the Indian Ocean offers big lessons on clean power

    The Indonesian island Sumba is working to provide 100% renewable electricity to all 650,000 residents by 2025. As the sun sets on the small Indonesian island of Sumba, Danga Beru Haba begins weaving under the glow of a single incandescent lightbulb, the only one in her home. Although she is tired from working dawn to dusk in the fields surrounding her village of ...

  • The ABCs of small hydro upgrade and automation

    Abstract - Small hydroelectric is increasingly depended on to provide regional power capacity, as municipalities seek more sustainable sources of energy. Yet, hydroelectric or hydro power has some negative perceptions. Other sustainable sources of energy like wind and solar power are early in their equipment and technology life cycles. Hydroelectric facilities are typically older and operate with ...

  • Implementation of a small hydro power project in India: issues and lessons

    In this paper, we present a longitudinal case study of a power sector start-up in India. Using the case as a starting point, we carefully analyse and explore the opportunities and challenges of implementing a small hydro power project in India. Using this case study, we identify the key success factors for a company to succeed in this sector. Based on first-hand observation of the progress of ...

  • Small hydro projects – renewable or ruinous?

    With thousands of rivers and streams running through British Columbia, small hydro energy projects seem like a significant source of renewable energy. Although such projects have low environmental impacts compared to major hydro-electric dams, they face a significant level of opposition from the public. ...

  • Control systems for small hydropower plants: a review

    Hydropower is emerging as a major contributor to world energy requirement. It is inexhaustible, clean and has many other benefits like flood mitigation, water supply, irrigation, etc. However, large-scale hydropower generation suffers from inherent disadvantages, such as massive financial outlays, long gestation periods, geological surprises, environmental factors and rehabilitation of the ...

  • A novel technique proposed for automatic control of small hydro power plants

    A new scheme is proposed for the speed control of hydro turbines. Power can be controlled by controlling the rotary motion of the spear valve or linear motion of the sluice gate. In this paper, necessity for speed control, various function of governors, types, speed regulation of micro-hydroelectric power plants, functional block diagram of power generation and control system general models for ...

  • Voltage controlled stand-alone microhydro induction generator system

    The paper discusses simulated control cases of the wound rotor self-excited induction generator WRSEIG. The generator external controller is designed to regulate the output voltage and frequency for constant or variable speed operation of the prime mover and has the inherent capability of protecting the load from short circuit, which permits voltage collapse under heavy loads. WRSEIG is ...

  • Control of dynamic effects in small hydro with long hydraulic circuits

    Lab tests in a long hydraulic circuit were developed to analyse hydrotransients induced by waterhammer effects under runaway conditions. The definition of suitable design criteria in hydraulic systems is of utmost importance and has become a priority for good design implementation. The dynamic behaviour of turbo-generators of small reaction turbines and the interaction with long hydraulic ...
