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...
Analysis of zero sequence passive filter harmonics mitigation device for building wiring system
- Trang 118-123 - 2002
In a normal office building wiring system, the supply is a three-phase four-wire
system and most of the nonlinear loads are single phased such as personal
computer and electronic office equipment. Rising main installation forms the
skeleton of the building wiring system. For balanced systems triplen harmonic
components of current are added in the neutral conductor, other components are
cancelled. ...
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...
Development of condition monitoring techniques for a transverse flux motor
- Trang 139-144 - 2002
Advances in electrical machine design have enabled Rolls-Royce to develop a
novel 20 MW machine for marine propulsion. This machine is named a transverse
flux motor (TFM) because of the three-dimensional flux paths created within it.
The TFM will potentially provide propulsion power to a fleet of future Royal
Navy vessels as part of the UK MoD drive towards the All Electric Ship (AES)
concept. To ...
MS4: a sign of the times
- Trang 41-46 - 2002
The latest type of Variable Message Sign (VMS) developed by the Highways Agency
is the MS4 (Motorway Signal Type 4). It is intended to optimise roadside
information delivery in the early 21st Century. A prototype has been built and
encouraging results have been obtained from an Off-Road Trial and plans for an
On-Road Trial are well advanced. This article outlines the MS4's development
process. A n...
A distributed optimum signal scheme for dynamic traffic control
- Trang 120-124 - 2002
In this paper, a prototype named distributed optimum signal scheme (DOSS) is
introduced. DOSS solves the generally recognized network-wide signal
optimization problem using an algorithm based entirely on dynamic programming.
It has been implemented and evaluated in a simulation testing environment, and
the simulation results indicate significant improvements compared to a
well-timed fixed-time con...
