Abstract

Description of program tools simplifying simulation applications building for physical phenomenons described by differential equations in state equations form modeling is presented in the paper. A method for using prepared libraries for squirrel-cage motors including any motor damages modeling had been described. For that purpose, squirrel-cage motor mathematical model in natural coordinates system had been presented. Presented solutions provide also supply sources (inverters) modeling, including their microprocessor implementation and other phenomenons, that assume state equation structure step changes, depending on variable limitations and time value.

Abstract

This paper addresses the state-variable stabilising control of the power system using such series FACTS devices as TCPAR installed in the tie-line connecting control areas in an interconnected power system. This stabilising control is activated in the transient state and is supplementary with respect to the main steady-state control designed for power flow regulation. Stabilising control laws, proposed in this paper, have been derived for a linear multi-machine system model using direct Lyapunov method with the aim to maximise the rate of energy dissipation during power swings and therefore maximisation their damping. The proposed control strategy is executed by a multi-loop controller with frequency deviations in all control areas used as the input signals. Validity of the proposed state-variable control has been confirmed by modal analysis and by computer simulation for a multi-machine test system.

Abstract

In this paper, the power factor correction system consisted of: bridge converter, parallel resonant circuit, high frequency transformer, diode rectifier and LFCF filter is presented. This system is controlled by a pulse density modulation method and the principle of its operation is based on the boost technique. The modeling approach is illustrated by an example using AC/HF/DC converter. Verification of the derived model is provided, which demonstrated the validity of the proposed approach.

Abstract

The article describes a shock safety modeling method for low-voltage electric devices, based on using a Bayesian network. This method allows for taking into account all possible combinations of the reliability and unreliability states for the shock protection elements under concern. The developed method allows for investigating electric shock incidents, analysing and assessing shock risks, as well as for determining criteria of dimensioning shock protection means, also with respect to reliability of the particular shock protection elements. Dependencies for determining and analysing the probability of appearance of reliability states of protection as well as an electric shock risk are presented in the article.

Abstract

Author presents an analytical method of calculation of unit power losses in magnetic laminations used in electrical machines and transformers. The idea of this method, based on the solution of Maxwell's equations in the lamination material, was described by the author in the previous work [3], taking into account approximation of constitutive static hysteresis loop by elliptic form of the function B = f(H) depending on magnetic saturation. In the previous formula for new isotropic and anisotropic materials it is needed to introduce so called "anomaly coefficient" deduced from the comparison of measured and calculated value of power losses in arbitrary excitation frequency for assumed induction. The method was tested by comparison with the results of experiments presented in commercial catalogues [1, 2]. Assuming superposition of harmonic power losses it is possible to enlarge this method for the estimation of overloss coefficient in dynamo sheet during axial magnetization with nonsinusoidal flux generated e.g. by PWM voltage supply.

Abstract

A role of radial corona current in a lightning discharge is discussed in the paper. It is shown that the corona current concept previously introduced by Cooray for lightning return stroke models of distributed-current-source (DCS) type, and later, by Maslowski and Rakov for lumped-current-source (LCS) type models enables to show duality between these two types of models. Further, it is demonstrated that the corona current is useful during consideration of dynamics of the lightning-channel corona sheath. As an example of application of presented approach a relaxation model of charge motion in the corona sheath is analysed together with plots which show the rate of expansion and shrinkage of the lightning corona sheath on both microsecond and millisecond time scales.

Abstract

This work presents the co-simulation approach to the analysis of control systems containing detailed models of electromagnetic and electromechanical converters. In this method of analysis the attention is paid to the whole system and not only to its electromagnetic part. The latter is described by equations resulted from the two-dimensional finite element discretisation of the Maxwell equations, and is coupled weakly with the remaining part of the system. The simulation is carried out in Matlab/Simulink environment wherein the coupling is realised through the S-function. Example results regarding simulation of the operation of the control system of an electrical machine and the operation of a power electronic converter are presented and compared with available reference data.

Abstract

The concept of inverse systems for standard and positive linear systems is introduced. Necessary and sufficient conditions for the existence of the positive inverse system for continuous-time and discrete-time linear systems are established. It is shown that: 1) The inverse system of continuous-time linear system is asymptotically stable if and only if the standard system is asymptotically stable. 2) The inverse system of discrete-time linear system is asymptotically stable if and only if the standard system is unstable. 3) The inverse system of continuous-time and discrete-time linear systems are reachable if and only if the standard systems are reachable. The considerations are illustrated by numerical examples.

Manuscript submission:

All manuscripts should be submitted electronically on Editorial System.

Submission of paper to the Archives of Electrical Engineering is understood to imply that the article is original, unpublished and is not being considered for publication elsewhere. All articles will be reviewed. Since 2013, Authors wishing to use the facility of colour printing should consult the editors.,

Template:

Microsoft Word is recommended as a standard word processor to prepare the paper to the AEE journal. If you use the LaTex format, please transfer your document to Microsoft Word and then use Template AEE.
Please use Template AEE to prepare your paper. Template can be download from journal page - www.aee.put.poznan.pl,

The reviewing process:

Each paper submitted for publication in Archives of Electrical Engineering is subjected to the following review procedure:
a) the paper is reviewed by the editor in chief or guest editor for general suitability for publication in AEE
b) if it is judged suitable two reviewers are selected and a double blind peer review process takes place
c) based on the recommendations of the reviewers, the editor then decides whether the paper should be accepted in its present form, revised or rejected
d) the author(s) is(are) informed by e-mail on the results of the reviewing procedure.
The papers are published on average within 3 months after acceptance.,

Requirements for preparation of manuscripts:

The manuscripts submitted for publication should not exceed 21 000 characters (ca. 12 pages of a manuscript written on an A4 sheet in Times New Roman, 10pt font size, single line spacing and 3.8 cm margins). The manuscripts, written in UK English, should be typed using Template AEE according to the following instructions and should include: a title page with the title of a manuscript, a short title; abstract; key words, text; list of references. A DOI number as well as received and revised data will be completed by Editor. When you open Template.doc, select "Print Layout" from the "View" menu in the menu bar (View > Print Layout). Then type over sections of Template.doc or cut and paste from another document and then use markup styles (Home > Styles). For example, the style at this point in the document is "main text").
All papers submitted for publication are assessed on the basis of the mutual anonymity rule as to the names of reviewers and authors. Authors' names and affiliations should not appear in the attached text/tables/figures.
If English is not your first language, ask an English-speaking colleague to proofread your manuscript. The manuscripts that fail to meet basic standards of literacy are likely to be immediately declined or after the language assessment, sent to the authors for linguistic improvement.
The manuscripts are published on average within 3 months after their acceptance.
Do not change the font sizes or line spacing to squeeze more text into a limited number of pages. Leave some open space around your figures.,

Text:

The pages must be numbered consecutively. Articles should be divided into numbered sections, and if necessary subsections, preferably: Introduction, Material, Methods, Results, Conclusion and References. Any special characters (e.g. Greek, script, etc.) should be named in the margin where the character first occurs in the text. Names of species are to be accentuated with wavy underlining (italics). Equations should be numbered serially (1), (2), ... on the right side of the page. Footnotes should be avoided, if required, they should be used only for brief notes which do not fit well into the text. Figures and tables have to be included into the text. If table is typed on a separate page its position in the text should be marked. Abbreviations should be explained when they first appear in the text.,

Math:

Please use the Microsoft Equation 3.0 editor (comes with Microsoft Office 2007 and later versions) or the MathML editor as well as MathType editor to build an equation in your manuscript.
To insert an equation in Word, choose Insert, then Object. This will bring up a dropdown menu, where the Object option should be chosen again. Pressing it opens a popup window, where the Create New option has to be clicked. Scrolling down the window allows to find Microsoft Equation 3.0.

,

Equations:

Equations should be typed within the text, centred, and should be numbered consecutively throughout the text. Their numbers should be typed in parentheses, flush right. Equations should be referred to in text, e.g. (1), except at the beginning of a sentence: "Equation (1) is ...". All symbols appearing in equations have to be defined in the text, before or just after the equation.
If the symbols are written in Times New Roman use italic fonts. Symbols of vectors and matrices should be written in bold fonts. Do not italicize Greek fonts and mathematical symbols like e.g.: the derivative symbol d, max, min, etc. The indices of symbols that are indices themselves should be written in a clear manner.
Note that the equation is centered using a center tab stop. Please keep the same font in the formulas and text.,

Unit Symbols, Abbreviations:

Define abbreviations and acronyms the first time they are used in the text, even after they have been defined in the abstract. Abbreviations such as IEEE, SI, MKS, CGS, sc, dc, and rms do not have to be defined. Do not use abbreviations in the title or heads unless they are unavoidable.
Si units are recommended for use in formulas, drawings and tables., for example the SI unit for magnetic field strength H is A/m. Apply the center dot to separate compound units.
Do not mix complete spellings and abbreviations of units: "Wb/m2" or "webers per square meter," not "webers/m2." Spell units when they appear in text: "...a few henries…", not "...a few H…".
Use a zero before decimal points: "0.25," not ".25." Use "cm3," not "cc."
Unit Symbols, SI Prefixes as well as Abbreviations should be writing in accordance with the IEEE standard,

Tables, figures (illustrations) and captions:

The illustrations (line diagrams and photographs) should be suitable for direct reproduction. The lettering as well the details should have proportional dimensions to maintain their legibility after the usual reduction. All illustrations should be numbered consecutively (Fig. X). Tables are numbered with Arabic numerals.
All figures, figure captions, and tables in the text must be inserted into the correct places.
Figures, photos, tables or other parts of a manuscript that have previously appeared in another publication or are not the property of the authors must be properly acknowledged in the manuscript. Permission to republish these items must be obtained by the corresponding author from a person or institution holding the copyright, usually the publisher.
Authors are requested to send figures (diagrams, line drawings and photographic images) in separate computer files. JPG, PNG or TIF are the recommended file formats. Photographs, colour and greyscale figures should be at least at a resolution of 400dpi. Linear, including tables should be at a minimum of 600dpi.
All colour figures should be generated in the RGB or CMYK colour space, while greyscale images in the greyscale colour space.
When preparing your figures/graphics etc., we suggest the use of the Arial 8 point font for axis numbers and Arial 9 point font for axis names. Figures/graphics etc. can be prepared in one of two proposed ways - see Template AEE.
Tables are numbered with Arabic numerals. Use 9 point Times New Roman for the title of the table and 9 point Times New Roman for the filling of the table (9 in the case of symbols with subscripts).
AEE journal allows an author to publish color figures in e-version at no charge, and automatically convert them to grayscale for print versions. Authors wishing to use the facility of color printing should consult the editors.,
