(Taylor & Francis Group, 19790101)The “new” generator reported here has been specially designed to decrease transient mechanical and heat loads. Essentially, this design allows the cold parts to rotate independently of the room temperature electromagnetic ...

(Taylor & Francis Group, 19940501)The paper describes a method for the analysis of induction motors. Such an approach is based on the use of Finite Element Method for simulating noload and locked rotor tests and for deducing the equivalent circuit parameters. ...

(Taylor & Francis Group, 19960401)A casebased intelligent system for predicting alternator dynamics is described, in which the appropriate knowledge is accumulated from offhne simulation using an accurate digital model. The approach is detailed in terms ...

(Taylor & Francis Group, 19791101)The paper describes a new chopper circuit capable of wide range of output voltage control and high frequency operation. The chopper has been analysed taking line inductance into account and expressions have been presented ...

(Taylor & Francis Group, 19890101)The modeling of random perturbations that occur in dynamic power systems is studied in this paper. These perturbations represent random fluctuations of various system components such as transmission lines and loads. Based ...

(Taylor & Francis Group, 19850101)This paper gives a study of line harmonics generated by threephase half controlled bridge converters feeding separately excited D.C. motor. Analytical expressions for line current are given and dominant current and voltage ...

(Taylor & Francis Group, 19870101)This paper describes a simple, efficient and flexible optimal method for estimating the state vectors of integrated multiterminal HV dc/ac systems. The approach adopted is sequential in nature in which the ac system is ...

(Taylor & Francis Group, 19771001)The theory of a companion circuit model of the induction motor is presented. The model comprises an independent current source in parallel with a constant resistance. Accuracy of problem solutions is the same as that ...

(Taylor & Francis Group, 19880101)A comparative analysis of efficient algorithms for optimum economic dispatching of electric power systems is presented. The problem deals with a system including thermal generation, to determine the optimum loading to ...

(Taylor & Francis Group, 19930901)A comparative study of the effects of the aircooling and watercooling methods used in the large hydraulic generators on the machine active materials costs. efficiency, daxis transient reactance, daxis subtransient ...

(Taylor & Francis Group, 19890101)The paper presents a comparison between the conventional and segmental reluctance motors. Four different motors have been considered and their performances are analyzed. The optimum electrical parameters, which provide ...

(Taylor & Francis Group, 19960701)A probabilistic formulation of power flow problem in which the number of equations is less than the number of the unknowns is discussed. The structure of the traditional Jacobian matrix encountered in conventional power ...

(Taylor & Francis Group, 19870101)In this paper the characteristics of two different types of switched reluctance motors have been predetermined using a two dimensional finite element analysis and compared. A motor with one tooth per stator pole and another ...

(Taylor & Francis Group, 19840101)The singlephase induction motor with yoke asymmetries can be calculated by means of the same computer program as the shadedpole motor and compared with it, if some reluctances are substituted by additional windings. The ...

(Taylor & Francis Group, 19911101)Dynamic performance of the singlephase induction motor is frequently evaluated using quasiac steady state methods. State variable methods have also been applied to the problem. This paper reports on a study to determine ...

(Taylor & Francis Group, 19780401)During the past few decades computers have been successfully used to perform numerical calculations and predetermined but complicated logical decisions in almost no time and at very reasonable cost. The ever increasing ...

(Taylor & Francis Group, 19941101)In this paper, the control area dynamics of power systems on automatic generation control are revisited. The role of reactive power flow between regions under automatic generation control is studied by review of simulations ...

(Taylor & Francis Group, 19780701)This paper explores the use of linear synchronous motor control to provide active damping for magneticallylevitated vehicles. Using a single LSM, only heave and surge damping can be provided, but, with a dual LSM, roll ...

(Taylor & Francis Group, 19840101)The nonlinear equations encountered in steady state and transient analysis of power systems are often linearized for use in iterative methods or small change sensitivity studies such as dynamic stability. In this work, the ...

(Taylor & Francis Group, 19860101)A discussion and analysis of adaptive acceleration factors for the NewtonRaphson power flow study are presented in this paper. The adaptive character is dependent on the improvement obtained at each iteration step. The ...
