Hvdc Transmission Technology Is Fast Advancing And Its Applications Are Rapidly Expanding. This Book Presents The Various Aspects Of Hvdc Technology In Sufficient Depth To A Beginner. In Addition, It Also Includes The Analysis And Simulation Of Ac-Dc System Interactions Which Are Of Importance In The Planning, Design And Operation Of Hvdc Systems. The Book Gives Up-To-Date Information And Integrates Material That Has Been Scattered In Several Journals.The Book Is Divided Into Two Parts. The First Part Has 9 Chapters And Covers The Techniques And Components Of Hvdc Systems In Detail. The Emphasis Is On The Unique Components Of Hvdc Systems, Such As Thyristor Valves, Converters, Control, Protection And Harmonic Filters. One Chapter Each Is Devoted To Each Of These Items. Reactive Power Control And Multiterminal Dc System Operation Are Also Included As Two Separate Chapters. Static Var Systems Used For Reactive Power Control In Converter Stations Are Also Discussed.The Second Part Of The Book Deals With The Modelling, Analysis And Simulation Of Ac/Dc Systems. Seven Chapters Are Included In This Part Which Cover Component Models, Power Flow, Transient Stability, Dynamic Stability And Power Modulation, Harmonic And Torsional Interactions, Simulation Of Converters And Hvdc Systems. The Coverage Is Fairly Detailed And Includes Some New Information Not Published Before.The Book Should Be Of Interest To Graduate Students, Researchers And Engineers From Utilities/Industries Who Are Involved With Hvdc Power Transmission.
