Abstract:

Appraisal and design of small-scale hydro power plants requires a knowledge of hydraulics, hydrology, civil, mechanical, and electrical engineering, and basic economics. Further, small hydro is site specific in nature and marginal from an economic view point. Methods of appraisal and design are required therefore that will keep engineering fees to a minimum and yet still achieve a reliable evaluation of scheme potential and economics. In this context it should be appreciated that small hydro is not large hydro scaled down, and that small hydro needs its own experts (Ref. 1). This thesis consid

Abstract:

Small hydropower offers many advantages as a source of energy and it has been successfully developed by the private sector in the U.S. and in Ontario. Although there is considerable interest in developing British Columbia's vast small hydro resource, there has been very little progress to date. The reasons for this are related more to economic and political factors than to technical issues. In this thesis I review the situation in B.C. and propose a policy framework for energy purchase price, one of the main issues involved in small hydro development. The price offered small hydro producers fo

Abstract:

The requirement for decentralised power generation in the rural electrification of developing countries is vast, and extensive hydrological resources for small-hydro power have been identified. Despite this, the utilisation of small-scale hydro is extremely slow, and the market is not fully developed. This study reviews the marketplace for small-scale hydro in the industrialised, newly-industrialised, less-developed and third-world countries. The extent, characteristics, and timescales of small-hydro development are used to estimate the market for varying levels of power generation technology.

The work presented in this thesis involves efficiency measurements performed with thethermodynamic method and the pressure time method. The thermodynamic method haslimitations with regards to the power plant head, as uncertainty will increase as the headbecomes low. The Pressure-Time method has limitations concerning geometrical propertiesof the waterways, as it demands a certain length of closed conduit with uniform area. Bothmethods are considered to cause relatively short downtime for turbines to be measured, andit is therefore of interest, for economical reasons, to expand the use of the m

Massive development of new renewable energy sources is taking place all over the world in 21st century and Europe is not an exception. Wind turbine parks are being planned and built on shore, in coastal zones and in the seas of European countries.With such a development of renewable sources comes a challenge of stable and continuous supply of electrical power which meets the demand. Renewable energy sources often have power output which cannot be easily regulated according to demand, but are rather fully dependent on forces in nature, such as a wind speed for wind power turbines, or solar radi

In this study the handling of debris in small hydro power intakes is assessed by evaluating the concept of back flushing with a horizontally fixed trash rack. The concept of back flushing is to reverse the flow over the trash rack for a short period of time in order to detach and evacuate clogged debris through a flushing pipe or gate. In this study the concept of back flushing with a horizontal trash rack is evaluated for two different designs; a one chamber design and a two chamber design. The one chamber design is based on H.

It eliminatesthe need of an inverter, conversion losses are avoided and less load is put on therectifiers. However the exclusion of an inverter also prevents the solar cells to have adirect connection to the grid,

Abstract:

Hydro power producers are faced with the task of releasing water from the reservoirs in the right time. To do this there are tools using stochastic optimization that aims at maximizing the income of that producer. The existing methods have a high computing time and grow exponentially with the size of the problem. A new approach that uses linear decision rules is investigated in this thesis to see if it is possible to maintain the same quality of the solutions and in the same time decrease run times. With this method the hydro power producer receives policies as an affine function of the realiz

Waterhammer is an undesirable event, caused by sudden flow changes in a confined pipe system. When it occurs, its consequences can be very costly and even sometimes deadly.

Abstract:

A onda de recessão econômica e de desaceleração do crescimento da década de 80, aliada à crise política e financeira vivenciada pelos Estados Nacionais na A.L., abriu terreno para que concepções neoliberais permeassem as decisões ligadas aos investimentos necessários em infra-estrutura. O Brasil, do Governo Collor ao FHC (1990 à 2002), seguiu esta orientação e, por meio dela, permitiu que vários segmentos dos serviços essenciais se tornassem passíveis de privatização e descentralização, dentre eles, o setor elétrico que foi reestruturado. Dado o contexto supra, este estudo visa analisar, sob u

Abstract:

Tem crescido a demanda por energia em todo o mundo. No Brasil, com o aquecimento da economia aumentam ainda mais as pressões. O parque gerador Brasileiro é fortemente baseado na geração hidrelétrica, que representa aproximadamente 77,6% da oferta de geração de eletricidade. Entre os impactos ambientais gerados pela construção de barragens e reservatórios de aproveitamentos hidrelétricos está a mudança do regime fluvial de jusante, a chamada vazão remanescente. Entre outros, esta vazão deve garantir as condições adequadas à sobrevivência e continuação das espécies e dos ecossistemas, associando

Abstract:

I Sverige finns det ungefär 2 100 vattenkraftverk som står för ca 40 % av Sveriges elproduktion.Ungefär 1 700 av dem är småskaliga vattenkraftverk och utgör 2,1 % av vattenkraftens elproduktion.Vattenkraften har negativa ekologiska konsekvenser på vattendragets konnektivitet vilket skaparproblem för den biologiska mångfalden. Tyresån vattensystem ligger i Stockholms län och är reglerat.Vattensystemet har tre vandringshinder, inklusive ett småskaligt vattenkraftverk – Uddby kvarn,vilket medför att vattensystemet har en dålig ekologisk status utifrån konnektivitet.

Abstract:

The thesis is focused on the examination of the utility of a synchronous generator of a small hydroelectric power station in the case of a change of working position of the machine. The utility will be measured on the basis of the examination of deformations and state of stress of the frame of the generator for the present running (with vertical axis of rotation of the generator) and subsequently for modified running (with horizontal axis of rotation). This will be accomplished partly on the static shell model by finite element method and consequently on the simplified dynamic model.

Abstract:

The aim of the diploma thesis is to create an algorithm by which it will be possible to devise management rules. These management rules will be able to advise a more efficient use of the hydroenergetic potential of reservoirs with run-of-river small hydro. The actual algorithm will be created with a view to maximizing the profit from the operation of the hydropower plant and using the time course of electricity prices on the market. The rules designed by algorithm will be tested in a simplified way in selected period using simulation model.
