In the paper are derived analytical expressions for calculation of values of transient resistances of electric arc in the case of interphase short circuits and also is performed numerical MATLAB simulation of electric arc in transient process. Modelling and simulation of electric network and arc was conducted in MATLAB Simulink surrounding, within the mathematical program MATLAB for simulation ...

In this paper, a hybrid technique is proposed for detecting the vibration signal of electric motor. The proposed hybrid technique is the combination of S-transformation algorithm and radial basis function neural network (RBFNN) technique. Initially, the pre-processing is applied in the electric motor signal such as normal and vibration. Then, the features of the signal are extracted by using S-...

In this paper, the stability of a functionally graded magneto-electro-elastic (FG-MEE) micro-beam under actuation of electrostatic pressure is studied. For this purpose Euler-Bernoulli beam theory and constitutive relations for magneto-electro-elastic (MEE) materials have been used. We have supposed that material properties vary exponentially along the thickness direction of the micro-beam. Gov...

This paper analysis overload control characteristics of the application server in the next generation electric communication network, as well as the application server overload detection requirements, propose an energy efficiency overload control algorithm based on particle swarm. First of all, we consider the problem of overload control and network efficiency at the same time, based on rate al...

This paper presents a comparative analysis of electric vehicles (EV) charging devices impact on microgrid. Increased load variation may create a need for upgrades in grid infrastructure. For this purpose a set of typical load profiles of EV charging modes is studied and presented. A software implementation and a 24h case study of low voltage distribution network with EV charging devices is pres...

With the widespread use of electric vehicles, their charging power demand has increased and become a significant burden on grids. The uncoordinated deployment vehicle stations uncertainty surrounding behaviors can cause harmful impacts during fast process especially is severely fluctuating, because its duration short rated chargers high. This paper presents methodology to analyze forecast aggre...

To conserve rare earth resources, consequent-pole permanent-magnet (CPPM) machine has been studied, which employs iron-pole to replace half PM poles. Meanwhile, increase flux-weakening ability, hybrid excitation CPPM with three-dimensional (3-D) flux flow proposed. Considering finite element method (FEM) is time-consuming, for the analysis of machine, this paper presents a nonlinear varying-net...
