This Book is a Complete, accessible and up to date guide how to Measure the harmonics components Present in power system signals and Subsequently Filtering of these harmonics using different types of active power filters. Design of Active Power Filters with Different control techniques is described in detail and it is investigated to Mitigate the harmonics and Enhance the Power quality in Power System. Ideas are given how to develop Estimation and Filtering algorithm and their real time Implementation. Series of Simulation and Experimentation are carried out to Prove the effectiveness and reliability of the Proposed Control techniques used for estimation and elimination of Power System Harmonics. The Information Presented is very Practical and easy to understand for engineers, researchers, Industrial Engineers and Technician working in the area of Power Quality. Coverage Includes: Power quality in Modern Power Systems, Power System Frequency Estimation Techniques, Power System Harmonics Estimation Techniques, Power System Harmonics Elimination Techniques, Design of Different Types of Filters.
