Forecasting real-time ratings for electricity distribution networks using weather forecast data
- Trang 1-4
Currently the operators of electrical distribution networks face a number of challenges, such as load growth, the proliferation of distributed generation and ageing infrastructure. This is drawing attention to techniques which will allow more efficient asset utilisation and facilitate network dynamic management. Power system component real-time ratings are a cost effective solution for increasing ......
Creating a successful payment architecture [mobile data services]
- Trang 376-381 - 2002
The introduction of GPRS and UMTS data services for mobile operators greatly increases the complexity of payment solutions since services can no longer be charged on simple duration basis but have to be tailored to the value of service being offered. At the same time, payment schemes need to be affordable and easy to understand for commercial success. The paper describes Nortel Networks' view of t......
Information architectures for next generation car park services
- Trang 74-77 - 2002
The car parking business must focus on customer service. This will progressively be about providing better information about spaces available and services to find the car park; for example, signs that light up to indicate the number of spaces available in a car park some way away. The common database architecture supports developing customer service and more cost effective monitoring for multivend......
Video-based vehicle and pedestrian tracking and motion modelling
- Trang 35-40 - 2002
ANDROID (Automated Numeration of Data Realised by Optimised Image Detection) is a collaborative, LINK-funded project between the University of Newcastle upon Tyne, Ross Silcock Partnership. (RSL) and the Defence, Evaluation and Research Agency (DERA). ANDROID is co-ordinated by RSL. The motivating idea for the project was to build upon research started under the DETR-funded Pedestrian Behaviour an......
Capability assessment of high-performance control schemes for PWM voltage-source rectifiers fed from weak power systems
- Trang 80-85 - 2002
It is a known fact that waning power systems worldwide are being supported using distributed power generation. This type of generation however adversely affects the end-users' power quality by increasing voltage and frequency disturbances. This paper presents a capability assessment of high-performance control schemes for PWM voltage source rectifiers operating under these conditions. The strategi......
An efficient algorithm for distributed power control in cellular radio systems
- Trang 123-127 - 2002
In most modern cellular radio systems, efficient interference management aims at acceptable carrier-to-interference (CIR) ratios in all active communication links in the system. Power control is an integral technique in the design and operation of such cellular radio systems. It can be used to reduce cochannel interference and hence the near-far effects. Two main approaches have been adopted for p......
A collaborative approach to the More Electric Aircraft
- Trang 223-228 - 2002
Significant changes are required in aircraft systems if dramatic reductions in the cost of ownership are to be achieved. One such change is the More Electric Aircraft (MEA). The MEA adopts a whole system approach to optimising the airframe and engine systems, proposing that significant benefits can be achieved if today's pneumatic, hydraulic and electric airframe power systems are replaced with pr......
Single phase active filter using a DSP with digital PWM
- Trang 604-609 - 2002
Several methods exist to reduce the harmonic content of nonlinear loads in the low-voltage grid to regulatory levels. Active filters have received significant attention over the past years and quite sophisticated control strategies have been proposed in the literature, even including neural networks. However, to demonstrate the operation of an active filter, these designs are usually overly comple......
FE analysis and design of electrical devices for automotive applications
- Trang 159-164 - 2002
In this paper, different approaches to the analysis and design of electrical devices for automotive applications are presented. These are mainly characterised by different finite element (FE) formulations (magnetostatic and electromagnetic quasi-static formulation), different geometrical hypothesis (2D and 3D domain) and different solutions of coupled problems (weak and strong coupling). Several c......
Economically optimised power dispatch in local systems using evolutionary algorithms and dynamic programming
- Trang 174-179 - 2002
The importance of local power systems is increasing all over the world. The small system size requires a high flexibility of the management system to follow the fluctuations in generation from renewable sources like wind and sun and in consumption caused by sudden switching of comparable large single loads. The energy management system described in this paper uses predictions of generated and cons......
