Public ISBD [article]  in IEEE transactions on energy conversion > Vol. 25 N° 1 (Mars 2010) . - pp. 265 - 267 Titre : Analysis of a self-excited induction generator with P –Q load model Type de document : texte imprimé Auteurs : Haque, M.H., Auteur Année de publication : 2010 Article en page(s) : pp. 265 - 267 Note générale : energy conversion Langues : Anglais (eng) Mots-clés : asynchronous  generators;  numerical  analysis Résumé : A simple method for analyzing the steady-state performance of a self-excited induction generator with P-Q load model is described in this letter. First, the basic operating equations of the generator are derived from its equivalent circuit, and then solved using a numerical-based routine. The proposed method is then tested on a 1.5-kW induction generator and the simulation results obtained are compared with the corresponding experimental values.

Determination of NEMA design induction motor parameters from manufacturer data / Haque, M.H. in IEEE transactions on energy conversion, Vol. 23 n°4 (Décembre 2008) 

Public ISBD [article]  in IEEE transactions on energy conversion > Vol. 23 n°4 (Décembre 2008) . - pp. 997 - 1004 Titre : Determination of NEMA design induction motor parameters from manufacturer data Type de document : texte imprimé Auteurs : Haque, M.H., Auteur Année de publication : 2009 Article en page(s) : pp. 997 - 1004 Note générale : Energy conversion Langues : Anglais (eng) Mots-clés : Equivalent  circuits;  induction  motors;  least  squares  approximations;  nonlinear  equations;  parameter  estimation;  rotors;  slip  (asynchronous  machines);  torque Résumé : This paper proposes a simple method of determining the equivalent circuit parameters of National Electrical Manufacturers Association (NEMA) design A and B types of induction motors from standard manufacturer data such as rated output power, starting torque, breakdown torque, and efficiency and power factor at rated output power. A set of nonlinear equations for various quantities is first derived from the equivalent circuit with a single-cage rotor model, and then, equate to the corresponding actual values supplied by the manufacturer. These equations are then solved using a least-squares based algorithm to determine the motor parameters. The rotor parameters are considered as slip dependent to predict the starting torque of the motor and that requires refining the breakdown torque equation as well as the slip at which the breakdown torque occurs. The proposed method of determining the motor parameters is then tested on more than 300 large-size HV induction motors. The effectiveness of the proposed method is evaluated by calculating various external quantities of the motors through the estimated parameters and comparing them with the corresponding actual values supplied by the manufacturer.

A novel method of evaluating performance characteristics of a self-excited induction generator / Haque, M.H. in IEEE transactions on energy conversion, Vol. 24 N° 2 (Juin 2009) 

Public ISBD [article]  in IEEE transactions on energy conversion > Vol. 24 N° 2 (Juin 2009) . - pp. 358 - 365 Titre : A novel method of evaluating performance characteristics of a self-excited induction generator Type de document : texte imprimé Auteurs : Haque, M.H., Auteur Année de publication : 2009 Article en page(s) : pp. 358 - 365 Note générale : energy conversion Langues : Anglais (eng) Mots-clés : Asynchronous  generators;  mathematics  computing;  nonlinear  equations Résumé : Self-excited induction generators (SEIG) are increasingly being used in isolated areas to generate electrical energy from both conventional and nonconventional energy sources. This paper proposes a novel method of evaluating the steady-state performance characteristics of a SEIG under various operating conditions. The criteria for the constant terminal voltage and the constant-stator-current operations are also derived and embedded into the system of equations. Unlike the previous methods of analysis, the problem is formulated in a simple and straightforward way without going through lengthy and tedious derivation for the coefficients of a set of nonlinear equations. The formulated problem is then solved using a numerical-based routine ldquofsolverdquo given in MATLAB. The effectiveness of the proposed method is then evaluated on a 220-V, 1.5-kW induction generator for various operating conditions. Some of the simulation results obtained by the proposed method are also compared with the corresponding experimental values and are found to be in very good agreement.
