Compendium of New Techniques in Harmonic Analysis

Harmonic analysis is a diverse field including such branches as signal processing, medical imaging, power electrical systems, wireless telecommunications, etc. This book is primarily written with the objective of providing recent developments and new techniques in harmonic analysis. In the recent years, a number of methods of quality control of signals under different perturbations, and especially the harmonics, have emerged. Some of these techniques are described in this book. This book is the result of contributions from many researchers and is a collection of eight research works, which are focused around the harmonic analysis theme but with different applications. The topics mainly concern the areas of medical imaging, biopotential systems, renewable energy conversion systems, wireless telecommunications, power converters, as well as the different techniques for estimating, analyzing, reducing, and eliminating harmonics

Control Strategy of Permanent Magnet Synchronous Generator for Stand Alone Wind Power Generation System

This paper presents the control strategy of the permanent magnet synchronous generator (PMSG) for stand-alone wind power generation system with battery energy storage management during wind speed and load variations. The complete system includes a PMSG connected to the load through a fully controlled back to back PWM converter and an intermediate DC link capacitor which is connected to a battery energy storage system through a bidirectional dc-dc converter. The control strategy to a stand-alone wind conversion system is divided into three parts: the control of PMSG side PWM converter employed to generate the maximum power (MPPT) during wind variations, a control strategy by bidirectional dc-dc converter developed to manage the power flow battery in different wind and load conditions, and a load side PWM converter controller is achieved to regulate the load voltage and frequency under varying wind and load conditions. The model system is developed in Matlab/Simulink environment with Power System Blockset (PSB). Simulation results confirm the effectiveness and performance of the control strategy
