		<description>
&lt;p&gt;To minimize the total harmonic distortion (THD) and improve the power factor (PF), this paper presents a comparative study between two techniques of shunt power active filter (SPAF) by a selective action of harmonics. These two techniques are based on the SAPF of certain low frequency harmonics (5th and 7th) whose identification of the harmonics of references of the first is made by the axis synchronous d-q of the Park, and the second is done by the approach of self-tuning filter (STF) (...)&lt;/p&gt;

		<description>
&lt;p&gt;The inrush currents generated during an energization of power transformer can reach very high values and may cause many problems in power system. This magnetizing inrush current which occurs at the time of energization of a transformer is due to temporary overfluxing in the transformer core. Its magnitude mainly depends on switching parameters such as the resistance of the primary winding and the point-on-voltage wave (switching angle). This paper describes a system for measuring the inrush (...)&lt;/p&gt;

 <content:encoded>&lt;div class='rss_chapo'&gt;&lt;p&gt;The inrush currents generated during an energization of power transformer can reach very high values and may cause many problems in power system. This magnetizing inrush current which occurs at the time of energization of a transformer is due to temporary overfluxing in the transformer core. Its magnitude mainly depends on switching parameters such as the resistance of the primary winding and the point-on-voltage wave (switching angle). This paper describes a system for measuring the inrush current which is composed principally of an acquisition card (EAGLE), and LabVIEW code. The system is also capable of presetting various combinations of switching parameters for the energization of a 2 kVA transformer via an electronic card. Moreover, an algorithm for calculating the saturation curve is presented taking the iron core reactive losses into account, thereby producing a nonlinear inductance. This curve is used to simulate the magnetizing inrush current using the ATP-EMTP software.&lt;/p&gt;&lt;/div&gt;

This paper presents simulation of improved incremental conductance method for maximum power point tracking (MPPT) using DC-DC cuk converter. This improved algorithm is used to track MPPs because it performs precise control under rapidly changing Atmospheric conditions, Matlab/ Simulink were employed for simulation studies.&lt;/p&gt;&lt;/div&gt;

Therefore the fault diagnosis methods are necessary. In this article, in order to anticipate the apparition of a dysfunction, either to avoid them, or to limit the consequences, we used a model-based fault diagnosis technique to detect and isolate sensor and actuator faults in the pitch systems of the wind turbine blades. It is about an observer applied on a &#034;Benchmark'' model for fault detection and isolation faults (FDI) in a wind turbine, the results of simulation by MATLAB / SIMULINK are presented to validate the efficiency of this diagnosis method.&lt;/p&gt;&lt;/div&gt;

		<description>
&lt;p&gt;The Analysis of electromagnetic interference between high voltage overhead power transmission lines and nearby gas/oil pipeline has been a topic of growing interest for many years. When pipelines are located in shared row with power lines, the pipeline can incur high induced voltages and currents due the AC interference. The induced voltage on pipeline can be dangerous for operator to touch the pipeline as well as pipe corrosion can result from AC discharge. This research evaluates and (...)&lt;/p&gt;

 <content:encoded>&lt;div class='rss_chapo'&gt;&lt;p&gt;The Analysis of electromagnetic interference between high voltage overhead power transmission lines and nearby gas/oil pipeline has been a topic of growing interest for many years. When pipelines are located in shared row with power lines, the pipeline can incur high induced voltages and currents due the AC interference. The induced voltage on pipeline can be dangerous for operator to touch the pipeline as well as pipe corrosion can result from AC discharge. This research evaluates and analyzes the electromagnetic interference effects on oil and gas buried pipelines created by the nearby high voltage transmission lines. The aim is to evaluate the AC corrosion likelihoods of pipelines and suggest proper mitigation solutions.&lt;/p&gt;&lt;/div&gt;

		<description>
&lt;p&gt;Concentrated Winding Permanent-Magnet (PM) Synchronous Machines (CWPMSM) are more and more used to drive electromechanical systems working in variable speed mode, such as Electric Vehicle (EV) and Hybrid Electric Vehicle (HEV) applications. In order to design and optimize these machines, the authors propose a semi-analytical method based on magnetic equivalent circuit (MEC).&lt;br class='autobr' /&gt;
The studied structure, 12-slots/8-poles CWPMSM, is an internal rotor topology with surface mounted PMs having radial (...)&lt;/p&gt;

We compare the results obtained with finite-element analysis (FEA) with those given by the MEC. In this paper both precision and time computation are evaluated in order to analyse the possible implementation of the model in an optimal design tool.&lt;/p&gt;&lt;/div&gt;
