Streszczenie:

Includes bibliographical references (leaves 75-78).<br>This thesis describes an investigation into the power quality of wind turbines and the impacts this could have on distribution networks. The main focus is on voltage fluctuations and flicker as grid connected wind turbines could have a huge impact on these, especially when connected to weak distribution networks.

Streszczenie:

This bachelor thesis examines the impacts of installed microgeneration of PV power in the distribution grid. The thesis examines the selected distribution grids power quality and how it is affected in terms of exceeding currents, voltages and reverse power flows and how the future trend of microgeneration of PV power will develop. A case study is made on Gotland with the support of the distribution grid owner, GEAB. Three of GEAB's distribution grids with different customer configurations and grid structures are being used to create different case scenarios. The production from the PV plants i

This project entitled 'The Economic Impact of Poor Power Quality to New Zealand' aims to identify the most problematic and costly power quality issues for industry and residential customers in New Zealand. The economic cost or poor power quality will be used by the EPECentre in their future power quality work. Some recommendations are included from the researcher where appropriate. Society is becoming more dependent on computers and digital circuitry. Industry, commercial and residential users are now dependent on a reliable, high-quality electrical power source to ensure these devices are ope

Streszczenie:

Wind generation is one of the most successful sources of renewable energy for the production of electrical energy. Wind power offers relatively high capacities, with generation costs that are becoming competitive with conventional energy sources. However, a major problem to its effective use as a power source is the fact that it is both intermittent and diffuse as wind speed is highly variable and site-specific. This is translated in large voltage and frequency excursions and dynamically unstable situations when fast wind power changes. Very high wind speeds will result in sudden loss of wind

Streszczenie:

Este trabalho apresenta a avaliação dos impactos elétricos da inserção da geração distribuída de sistemas fotovoltaicos conectados à rede de distribuição em baixa tensão, com a finalidade de identificar os impactos e demonstrar que estes podem ser controlados. O estudo consistiu de uma avaliação teórica e de um estudo de caso da inserção da geração fotovoltaica considerando aspectos da qualidade de energia da rede, curva de carga resultante, vida útil de transformadores e gestão ativa da demanda. Os resultados mostraram que a inserção da geração fotovoltaica na rede de baixa tensão altera a cu

Las lentes progresivas (LP) para gafas es una solución muy extendida para la presbicia, ya que proporcionan una visión continua a todas las distancias debido a un cambio progresivo de potencia. En este trabajo se han medido las aberraciones de frente de onda espacialmente resueltas y la calidad visual en estas lentes. Además del astigmatismo que aumenta periféricamente, también se han encontrado pequeños valores de aberraciones de tercer orden, coma y trefoil, que producen un bajo deterioro de la calidad óptica y visual.

Streszczenie:

With the export of coal being more lucrative than selling coal to South African power producers, power station operators might consider accepting lower-quality coal. While the impact lower quality coal has on cycle efficiency is understood, the influence it has on equipment reliability and lifetime is often not understood. This study focusses on addressing the question of how different characteristics of coal influences different damage mechanisms of common power station equipment. The results are translated into a reference framework that can be used when coal quality variation is expected. T
