   A New Hybrid Filter Versus a Shunt Active Power Filter
By J. Jacobs; D. Detjen; R. W. De Doncker [View]
[Download]

Abstract: In this paper a new Shunt Hybrid Power Filter (SHPF) to compensate harmonic currents is proposed. The SHPF comprises power factor correction capacitors and a transformer in series. The primary windings of the transformer are fed by a three-phase current controlled voltage source inverter. The working principle and the control strategy of the SHPF is discussed in detail. Simulations show the performance of the proposed filter. Furthermore, the performance of the SHPF is compared to the performance of the well-known Shunt Active Power Filter (SAPF). It is shown that better results are achieved with the new SHPF topology. To verify the simulations, a laboratory prototype was built. The experimental results of this prototype are compared to detailed simulations.

   Active Power Levelling With Capacitor Energy Storage
By M. Nowak; J. Matulka; R. Barlik [View]
[Download]

Abstract: The paper concentrates on the use of DC capacitor energy storage for compensation of power pulses caused by a specific type of load (i.e. drives, welding etc. ). Two different solutions have been taken into consideration and presented in the paper. The first one – very simple and economic, depends on power pulse compensation affecting the DC voltage intermediate link in the converter plant. Control of such a DC/DC converter can be done very simply with the use of analogue technology. The second solution, more universal, because although the use of a three phase PWM line converter which can generate all power components is more complicated and expensive it may be economical as a development or supplement of a complex power conditioning system. Control in this case is also quite complex and needs the use of a powerful DSP. Both solutions are presented but the main considerations are designed for universal AC grid active power consumption levelling.

   Application Of Genetic Algorithm In Double Tuned Filters Design
By R. Klempka; Z. Hanzelka [View]
[Download]

Abstract: Passive power harmonic LC filters still are a common way of reduction of the voltage distortion. One of the possible configurations is a double tuned filter used in large power systems and in specific industrial applications. Design of such a filter can be brought to solution of multi-criterial optimisation problem applying the genetic algorithm. The paper presents an original programme developed in the MATLAB environment, employing in its first part such algorithms, designed to higher orders filters design. Comparison of results obtained by means of other methods with the results obtained using the genetic algorithm indicates on substantial usability of the proposed method. The second element of the design procedure is modelling of the whole system: supply network - load - filter in order to verify values of voltages and currents in the system components in various states of operation and failure states. This ensures proper choice of the filter components ratings.

   Control of 50Hz-16Hz2/3 inverter for 15kV railway network
By G. De Préville; O. Lapierre; D. Matuszak [View]
[Download]

Abstract: Static Frequency Converters (SFC) are more and more used to supply the railways single phase grid 16Hz2/3 and 25Hz. This paper shows a two SFC realisation 15MVA 16.5kV 16Hz2/3 each for the Swedish railways transportation in 3 level GTO technology. Focus of this article is power control of the Static Frequency Converter, after a brief description of the equipment. The control of the SFC guarantees an appropriate operation at all possible states of the railway grid (i.e. single supply, parallel operation with rotating converter and others substations)

   Energy Storage for Industrial Processes
By R. G. Lawrence; K. L. Craven [View]
[Download]

Abstract: The provision of energy storage enables industrial processes to ride through the potentially devastating effects of the temporary loss of electrical supply. This paper describes two energy storage devices: a low speed flywheel providing energy to an extruder and an ultra capacitor providing energy to a water pumping system.

   Fault Detection And Classification Approach For A Converter Fed Pmsm
By O. Curea; B. Dakyo; G. Barakat; J. Raharijaona [View]
[Download]

Abstract: The aim of the study is to carry out a converter fed machine behaviour and malfunction from only electrical data (voltages and currents). In this purpose, based on phasor diagram, Fourier transform and complexified power analysis, we present here the neural networks and fuzzy logic techniques for detection and classification.

   Managing Utltracapacitors Energy to feed EV DC Bus
By A. Djerdir; D. Bouquain; H. Gualous; A. Berthon [View]
[Download]

Abstract: The aim of this paper is to insert the ultracapacitors into an electric vehicle. Ultracapacitors are intended to drive electric motors when overloaded. They also recover energy coming from motors during an electric braking. Finally, they are charged starting from the vehicle DC bus. A DC/DC converter able to carry out the above functions and based on the boost/buck topology has been proposed.
