Forecasting real-time ratings for electricity distribution networks using weather forecast data
- Trang 1-4
Andrea Michiorri, Philip C. Taylor
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 ... hiện toàn bộ
Creating a successful payment architecture [mobile data services]
- Trang 376-381 - 2002
T.R. Longman, T. Roberts
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... hiện toàn bộ
Information architectures for next generation car park services
- Trang 74-77 - 2002
M.E. Percival, A. Sedgwick
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... hiện toàn bộ
A parallel OPF approach for large-scale power systems
- Trang 161-166 - 2002
Y. Huang, T. Kashiwagi, S. Morozumi
In this paper, the Newton-Krylov algorithm of power flow calculation is reviewed. A rectangular coordinate voltage formulation of nonlinear optimal power flow (OPF) is introduced and adopted into the unlimited point algorithm, and a Newton-Krylov algorithm similar to that of power flow calculation is proposed to solve the unlimited point transformed optimality conditions for the original OPF probl... hiện toàn bộ
Extended vector control of doubly fed machine under unbalanced power network conditions
- Trang 329-334 - 2002
M. Chomat, J. Bendl, L. Schreier
The present paper analyses operation of a power unit with a doubly fed machine under the condition of unbalanced voltage supply applied to the stator. An extended vector control method is proposed to increase the immunity to a negative-sequence voltage component and to improve the controllability of such a power unit.
Implementation of online air-gap torque monitor for detection of squirrel cage rotor faults using TMS320C31
- Trang 128-132 - 2002
V.V. Thomas, K. Vasudevan, V.J. Kumar
This paper proposes a digital signal processor (DSP) based implementation of online air-gap torque estimator for detection of squirrel cage rotor faults. Two noninvasive, computationally efficient methods for online air-gap torque monitoring are discussed. In both the methods, the air-gap torque is computed from two stator voltages and currents and is cost effective when compared with the use of a... hiện toàn bộ
Precise UE positioning in UMTS using cumulative virtual blanking
- Trang 355-359 - 2002
P.J. Duffett-Smith, M.D. Macnaughtan
The current observed time difference of arrival technique for finding the position of a mobile in a UMTS network suffers from a severe near-far problem when the UE is close to a node B. We describe a new technique, called cumulative virtual blanking, for overcoming this problem efficiently, without disrupting the normal operation of the network. Early results from a network-based trial indicate po... hiện toàn bộ
On the implementation and optimisation of LDPC codes on a reconfigurable hardware for future communications systems
- Trang 196-200 - 2002
D. Barral, W. Falcon, J. Altuna, R.A. Carrasco
With the advent of new services and capabilities for next generation mobile communication systems, new powerful error-correcting schemes have emerged to increase cellular capacity and achieve higher transmission data rates effectively. A new set of error-correcting codes (ECCs), called low-density parity check codes (LDPCs), significantly reduce error-rates compared to conventional ECCs. This codi... hiện toàn bộ
A low speed reciprocating permanent magnet generator for direct drive wave energy converters
- Trang 468-473 - 2002
M. Mueller, N.J. Baker
The design of a prototype linear variable reluctance permanent magnet machine is outlined in this paper. It has been built to investigate operation at speeds of 0.5 m/s, which is typical of a wave energy converter. Results are presented to verify the design, and to investigate the performance of the machine. In order to optimise power conversion, methods of compensating for the effects of the high... hiện toàn bộ
Optimised torque control of marine transverse-flux propulsion machines
- Trang 1-6 - 2002
C.D. French, C. Hodge, M. Husband
This paper focuses on describing a generalised approach to torque control that utilises the motor's magnetic flux characteristic that ensures that maximum torque is produced for minimal input power. The method is generalised for any separately excited synchronous, permanent magnet or reluctance machine, including axial flux machine (AFM) and transverse flux machine (TFM). A TFM motor is used to il... hiện toàn bộ
