• ### Simulation of transients on transmission lines with corona via the method of characteristics

Publication Year: 1995, Page(s):81 - 87
Cited by:  Papers (14)
| | PDF (488 KB)

Fast transients on power transmission systems, such as those produced by lightning and faults, are usually modelled by the Telegrapher's Equations. Because of corona, these equations are often nonlinear. It has long been recognised that the method of characteristics provides considerable advantages in dealing with these equations. To the best of the authors' knowledge, the first successful applica... View full abstract»

• ### HVDC convertor waveform distortion: a frequency-domain analysis

Publication Year: 1995, Page(s):88 - 96

| | PDF (492 KB)

A linear and direct method of determining the major components of noncharacteristic waveform distortion at the terminals of an HVDC convertor is presented. The method is a development of the frequency-domain transfer function technique, and relates the AC current and DC voltage to distortion in the firing angle, AC voltage and DC current. The consequential effects of the commutation period and its... View full abstract»

• ### Optimal choice of fixed and switched capacitors in radial distributors with distorted substation voltage

Publication Year: 1995, Page(s):24 - 28
Cited by:  Papers (12)
| | PDF (296 KB)

The problem of optimal choice of fixed and switched capacitors in radial distributors with distorted substation voltages is formulated and solved by decomposition through isolated subproblems. The maximum sensitivities selection (MSS) method, which is used to solve the optimisation problem of the subproblems with discrete variables, is proposed. The results of a test distributor show that harmonic... View full abstract»

• ### Maximum photovoltaic power tracking: an algorithm for rapidly changing atmospheric conditions

Publication Year: 1995, Page(s):59 - 64
Cited by:  Papers (566)  |  Patents (7)
| | PDF (412 KB)

As the maximum power operating point (MPOP) of photovoltaic (PV) power generation systems changes with changing atmospheric conditions (e.g. solar radiation and temperature), an important consideration in the design of efficient PV systems is to track the MPOP correctly. Many maximum power tracking (MPT) techniques have been considered in the past but techniques using microprocessors with appropri... View full abstract»

• ### Optimal pricing of transmission and distribution services in electricity supply

Publication Year: 1995, Page(s):1 - 8
Cited by:  Papers (14)
| | PDF (616 KB)

A new strategy for the separate pricing of transmission and distribution services in electricity supply is formulated and evaluated. The proposed methodology is a multivariate transmission generalisation of the method of peak load pricing previously applied to the optimal time-of-use pricing of generation on a power system with diverse generation technologies and with elastic demand. The method al... View full abstract»

• ### Optimal-power-flow solution by Newton's method applied to an augmented Lagrangian function

Publication Year: 1995, Page(s):33 - 36
Cited by:  Papers (17)
| | PDF (256 KB)

The paper describes a new approach to the optimal-power-flow problem based on Newton's method which it operates with an augmented Lagrangian function associated with the original problem. The function aggregates all the equality and inequality constraints. The first-order necessary conditions for optimality are reached by Newton's method, and by updating the dual variables and the penalty terms as... View full abstract»

• ### Digital simulation of fault location on EHV lines using wideband spread spectrum techniques

Publication Year: 1995, Page(s):73 - 80
Cited by:  Papers (2)  |  Patents (2)
| | PDF (564 KB)

Spread spectrum techniques perform well in high-noise environments such as power lines, and their use in radar ranging is well known. Existing power line carrier (PLC) equipment may be used to transmit a direct sequence signal down a faulted EHV line. The fault position may then be calculated from correlation analysis of the reflected waveforms. This fault-location process has been simulated on a ... View full abstract»

• ### Reactive reserve management

Publication Year: 1995, Page(s):17 - 23
Cited by:  Papers (3)
| | PDF (456 KB)

A methodology is proposed in steady state to determine the output or setting of existing VAr/voltage control devices so that the allocation of reactive reserves guarantees that the system does not move towards voltage collapse as demand changes and that it will cope under credible contingency conditions. The procedure is to define reactive areas' by identifying weak' circuits and then to assess ... View full abstract»

The paper is devoted to the development of a neural network architecture which implements the Newton-Raphson algorithm for solving the set of nonlinear equations of power-system load-flow analysis. The principal context is that of online network analysis in energy management systems with particular reference to the optimal power-flow function. The author shows that the complete Newton-Raphson load... View full abstract»

• ### Rule-based variable-gain power system stabiliser

Publication Year: 1995, Page(s):29 - 32
| | PDF (260 KB)

The paper presents a rule-based variable-gain power system stabiliser (PSS) for power systems, which has been implemented in the laboratory by transputers for real-time control tests. This stabiliser has been developed from the conventional PSS, but with a variable gain, which is adjusted on-line to meet the damping requirement of power systems. The real-time adjustment of the stabiliser gain is b... View full abstract»

• ### Experimental validation of a numerical model of busbar systems

Cited by:  Papers (4)
| | PDF (588 KB)

The paper deals with the experimental validation of a numerical model for the steady-state analysis of multiconductor busbar systems. The computational approach employs the finite element technique to solve the two-dimensional electromagnetic field problem and deduce a complex impedance matrix. Such a matrix, inserted in the circuit equations, enables prediction of the system behaviour. The analys... View full abstract»

• ### Economic evaluation of reliability-centred maintenance (RCM): an electricity transmission industry perspective

Publication Year: 1995, Page(s):9 - 16
| | PDF (780 KB)

Traditional approaches to appraising the introduction of reliability centred maintenance (RCM) are shown to exhibit severe limitations. In particular, the economic implications surrounding its adoption are repeatedly misstated, with the consequence that organisations may be investing in unprofitable RCM ventures. Previously quoted benefits are examined and, contrary to established opinion, it is s... View full abstract»

A description and original application of a type of neural network, called the radial basis function network (RBFN), to the short-term system load forecasting (SLF) problem is presented. The predictive capability of the RBFN models and their ability to produce accurate measures that can be used to estimate confidence intervals for the short-term forecasts are illustrated, and an indication of the ...
