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 ...
A review of control methods for brushless doubly-fed reluctance machines
- Trang 528-533 - 2002
This paper considers various aspects of field oriented control, direct torque
control and scalar control of an ideal brushless doubly-fed reluctance machine
(no saturation and with sinusoidally distributed windings). Modeling
fundamentals are introduced first and mathematical expressions of interest to
the primary flux oriented control for the machine are subsequently derived from
the model equati...
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...
Coexistence issues for 2.4 GHz OFDM WLANs
- Trang 400-404 - 2002
OFDM-based wireless LANs will be implemented in the 2.4 GHz ISM band as well as
the 5 GHz band. OFDM WLANs provide very high data rates, resilience to multipath
and extended operating range. However, they will encounter new interference
sources, foremost among them being Bluetooth devices. The paper looks at the
coexistence of OFDM WLANs with Bluetooth devices and the use of symbol erasures
to ame...
Resource allocation algorithms and power control for cellular systems
- Trang 118-122 - 2002
Multiband (or multi-carrier) CDMA is a promising approach to increasing the
capacity of CDMA systems, while maintaining compatibility with existing systems.
This paper surveys three different power control based resource allocation
algorithms and proposes a modified joint band allocation, beamforming and load
sharing algorithm. This algorithm will solve the problem of degradation in
performance at...
Remote diagnostics of generator excitation systems
- Trang 145-148 - 2002
Modem synchronous generators in power stations, applied as turbogenerators or
hydrogenerators, require sophisticated excitation systems to control the voltage
and the reactive power of the system. This paper describes the modem application
of computer and communications technology to the monitoring of such excitation
systems. The paper describes the choice of communications, the selection of the
n...
Can ITS satisfy the demands of the Integrated Transport White Paper?
- Trang 1-8 - 2002
Presents some of the key conclusions of an analysis of strengths, weaknesses,
opportunities and threats related to intelligent transport systems (ITS).
Discusses in detail what ITS can offer to support the objectives of the UK
Government's White Paper on transport, of 1998, and the aspirations of the more
recent 10-year plan, with reference to the technical developments presented into
the broader ...
Investigation into the enhancement of substation automation systems using visual programming technique
- Trang 439-444 - 2002
This paper is a result of an investigation into visual programming methods and
their. effective use in substation applications. It particularly concerns with
developing a software-based tool for the design of composed object types (COT)
as applied to substation automation and control systems. A brief discussion
illustrating that substation automation and control systems can be developed
using COTs...
A study of characteristics of motorway vehicle breakdown duration
- Trang 151-155 - 2002
This paper presents an analysis of vehicle breakdown duration on motorways. The
distribution of breakdown duration was shown to be statistically significantly
different for three categories of vehicle type and were shown to conform to a
Weibull distribution. A predictive vehicle breakdown duration model was
developed, based on fuzzy logic. The variables used in this model were: vehicle
type, break...
