Nowadays; Rwanda is one of the country which is under developing country and one of the strategy to be used is to explore and develop the sector of energy in Rwanda. Our country Rwanda needs to develop the rural electrification sectors in order to provide illumination to the population living in those rural areas for rapid development in different sectors like schools; health centers; business centers; administrative officers. As MSE we have this opportunity to show our contribution by making a feasibility study of Gisuma Micro-hydropower plant in Gisagara District. A micro hydropower is used

Abstract:

The discharge through a river hydropower plant must be controlled such that the water level at a pre-specified point close to the facility is kept within given bounds. The controllers used today have a somewhat demanding tuning and often create too much amplified, unnatural discharge variations resulting in unsatisfactory control performance.This will affect both surrounding nature and imposing problems for river navigation. This thesis will present a new type of controller called Override Selector feedback Control that adds an estimator for the water levels and water flows in the up- and down

At the intake of hydropower plants, air-core vortex formation is known to cause severe damage. In order to study how to prevent and reduce the origin of the vortex, Vattenfall has built a scale model of the Akkats hydropower plant dam, where scale testing is possible. This thesis work consists of discerning whether Computational Fluid Dynamics (CFD) in terms of solving the Unsteady Reynolds Average Navier-Stokes equations (URANS) can be used as a complement to scale testing. For this work, the RNG k-epsilon turbulence model is chosen, and the flow field is solved with implicit time discretizat

Abstract:

The development of hydroelectric power production and the damming of water courses that ensues causes a threat to the migration patterns of Atlantic salmon (Salmo salar), by altering their habitat and compromising river connectivity. Because the species’ survival heavily depends on the completion of their migration between rivers and oceans, the design of guidance structures that promote successful passages around dams is a critical goal. Physical structures have been used to steer downwards-migrating smolts through safe fishways but they have not always proven effective, both from an ecologic

Hydropower is one of the oldest renewable energy (RE) sources and constitutes a major share in the Swedish electricity mix. Though hydropower is renewable, there exist some issues pertaining to the local aquatic conditions. With more environmental laws being implemented, regulating the use and management of water is jeopardizing the flexibility of hydropower plants. The decided national plan for new environmental conditions in Sweden is expected to start being implemented in 2025 and more restrictions are expected.

Abstract:

Fragmentation of rivers due to the rapid expansion of hydropower plants is one of the major factors responsible for the decline in the Atlantic salmon (Salmo salar L.) in the Baltic Sea. Current methods to aid downstream migrating salmon smolt still struggle with effectively stopping the smolt from going through the hydropower turbines, by guiding them towards the available salmon ladders. A promising guiding method is using a barrier of bubbles which may serve as a non-intrusive alternative to conventional guiding structures.

Hydropower is the most important power balancing resource in the Swedish electrical power system, regulating the power supply to match the load. Consequently, several hydropower plants have periods of stand-by operation where the power production is absent but where several devices within a plant are still active. Such a device is the step-up power transformer, which during stand-by operation still generates no-load energy losses. These losses can accumulate to a considerable amount of energy and costs during the long technical lifetime of the apparatus. One option to minimize these no-load en

Abstract:

Дисертація присвячена системному аналізу природно-техногенної безпеки (ПТБ) гідровузлів (ГВ) України на прикладі 18 найбільших об’єктів галузі. У роботі здійснено класифікацію факторів загроз ПТБ ГВ і заходів із запобігання їм, побудовано відповідну ієрархічну структуру. На основі експертних оцінок для кожного об’єкта здійснено ранжування вказаних факторів та заходів, розраховано значення інтегрального показника небезпеки (ІПН), а також перевірено відповідність основних споруд досліджуваних ГВ класам відповідальності за наслідками. На основі систематизованих даних державних і місцевих

Abstract:

This master’s thesis deals with a new design of bar screens. The goal was to come up with an alternative design to already existing device by INKOS a. s. In the first part, there is a summary of various machines working in similiar conditions. The insights gained by this research influenced the design of the new device. It utilizes well proven solutions from previous projects, but some of these were reworked and a few new functions were added. Second part of the thesis describes the analytical solutions, which were used to determine the forces in the assembly during the operation of the device

Abstract:

Sri Lanka has a number of small waterfalls and channels. Related to this there is a significant potential to develop small hydropower plants, thus to generate much needed electricity for country’s development efforts. Small hydro power plants cause less environmental effects compared to large scale hydro power generation and power generation using fossil fuel. Therefore, it is a timely requirement to explore the possibilities of utilizing small water streams to generate electricity as much as possible as well as to optimize the energy generation with the available water in those water strea

Abstract:

abstract: Hydropower generation is one of the clean renewable energies which has received great attention in the power industry. Hydropower has been the leading source of renewable energy. It provides more than 86% of all electricity generated by renewable sources worldwide. Generally, the life span of a hydropower plant is considered as 30 to 50 years. Power plants over 30 years old usually conduct a feasibility study of rehabilitation on their entire facilities including infrastructure. By age 35, the forced outage rate increases by 10 percentage points compared to the previous year. Much lo
