Abstract:

The use of electricity in 21st century living has been firmly established throughout most of the world, correspondingly the infrastructure for production and delivery of electricity to consumers has matured and stabilised. However, due to recent technical and environmental–political developments, the electricity infrastructure worldwide is undergoing major restructuring. The forces driving this reorganisation are a complex interplay of technical, environmental, economic and political factors. The general trend of the reorganisation is a dis–aggregation of the previously integrated functions of

Abstract:

This thesis proposes an efficient power system simulator to estimate the automatic sequence of events that follow a fault contingency leading to islanding and cascading outages. The simulator is based on a quasi-steady state model that includes island identification, under-frequency load shedding, over-frequency generator tripping, and island load flow. Contingencies can include the outage of generators, loads, or transmission lines. Often times, a fault of one or two of these power system elements can lead to many cascaded outages and system islanding. The simulator utilizes an innovative met

Power-split hybrid-electric vehicles (HEVs) provide two power paths between the internal combustion (IC) engine and the driven wheels through gearing and electric machines (EMs) composing an electrically variable transmission (EVT). EVTs allow IC engine control such that rotational speed is independent of vehicle speed at all times. By breaking the rigid mechanical connection between the IC engine and the driven wheels, EVTs allow the IC engine to operate in the most efficient region of its characteristic brake specific fuel consumption (BSFC) map.

This work demonstrates the use of digital simulation for analyzing protection system performance. For studies of complex, multi-relay protection systems, digital simulation provides utility engineers with an attractive alternative to relay testing techniques. The cost of digital simulation facilities can be lower than the cost of comparable testing facilities; relay hardware does not have to be made available for the test laboratory. Digital simulation would ordinarily be impractical for security and dependability studies, due to the thousands of individual simulations involved. The number o

Abstract:

Modern aircraft, military and commercial, rely extensively on hydraulic systems. However, there is great interest in the avionics community to replace hydraulic systems with electric systems. There are physical challenges to replacing hydraulic actuators with electromechanical actuators (EMAs), especially for flight control surface actuation. These include dynamic heat generation and power management. Simulation is seen as a powerful tool in making the transition to all-electric aircraft by predicting the dynamic heat generated and the power flow in the EMA. Chapter 2 of this dissertation des

Abstract:

With increasing costs of fossil fuels and intensified environmental awareness, low carbon vehicles, including hybrid electric vehicles (HEVs), are becoming more popular for car buyers due to their lower running costs. HEVs are sensitive to the driving conditions under which they are used however, and real-world driving can be very different to the legislative test cycles. On the road there are higher speeds, faster accelerations and more changes in speed, plus additional factors that are not taken into account in laboratory tests, all leading to poorer fuel economy.

Abstract:

The proliferation of electronic equipment that is permanently connected to the grid causes significant parasitic losses. Yet, the design of power supplies for PCs, servers, multi-function printers, etc, is governed by the cost and component specifications at the peak operating point as well as the thermal management of the power supply itself. Most power supplies have lower efficiencies at light loads than at their rated loads. If the unit spends most of its time at the light load operating point, then the energy consumption will be much higher compared to a situation where the power supply is

To combat global climate change, the reduction of carbon emissions in different industries, particularly the power industry, has been gradually moving towards a low-carbon profile to alleviate any irreversible damage to the planet and our future generations.

However, renewables such as solar and wind are stochastic in nature and difficult to predict accurately.

Abstract:

CAPES; CNPq<br>O constante aumento na velocidade da rede, o número de ataques e a necessidade de eficiência energética estão fazendo com que a segurança de rede baseada em software chegue ao seu limite. Um tipo comum de ameaça são os ataques do tipo probing, nos quais um atacante procura vulnerabilidades a partir do envio de pacotes de sondagem a uma máquina-alvo. Este trabalho apresenta o estudo, o desenvolvimento e a implementação de um algoritmo de extração de características dos pacotes da rede em hardware e de três classificadores de aprendizagem de máquina (Árvore de Decisão, Naive Bayes

Abstract:

A successful power system in military applications (warship, aircraft, armored vehicle etc.) must operate acceptably under a wide range of conditions involving different loading configurations; it must maintain war fighting ability and recover quickly and stably after being damaged. The introduction of energy storage for the power system of an electric warship integrated engineering plant (IEP) may increase the availability and survivability of the electrical power under these conditions. Herein, the problem of energy storage control is addressed in terms of maximizing the average performance.

Abstract:

Ces travaux, initiés par le CNES et la SNECMA, sont principalement consacrés à la simulation numérique d'écoulements turbulents supersoniques en présence d'interactions ondes de choc/couche limite. L'étude de ces écoulements, sièges de phénomènes complexes, se révèle être d'une importance particulière en vue du dimensionnement d'organes de propulsion de lanceurs spatiaux. Il a été choisi, dans ce travail, d'investir les aspects instationnaires au moyen de la simulation des grandes échelles turbulentes. Les contraintes liées au traitement numérique ont aboutit au développement d'un schéma numér

Abstract:

Ce travail de thèse a été consacré au développement d'outils numériques pour aider à la compréhension, par simulation numérique, de l'aérodynamique d'un inverseur de poussée à portes (écoulement turbulent compressible). Dans cette étude, nous avons adopté deux approches complémentaires : résolution des équations de Navier-Stokes moyennées RANS (stationnaires) ou filtrées LES (instationnaires). Dans un premier temps, les divers phénomènes physiques présents dans un inverseur de poussée sont décomposés et étudiés séparément. On simule ainsi successivement :<br /> (1) un écoulement décollé (march
