The application of HVDC technology has received new impetus with the evacuation of large quantum of power from remote hydro and thermal stations. In addition, the controlability of power flows in the power grid has added a new dimension ot the use of HVDC links in the context of developing Smart Grids. The power transfer from off-shore wind generation is another new application. DC transmission at distribution level voltages (using VSC-HVDC) is also being considered for integration of distributed generation in the power grid. The emerging technology of VSC-HVDC links is described in detail. Instead of adding new chapters to present new developments, the new material is added at the appropriate places. The book also presents other developments such as the application of hybrid active filters, capacitor commutated converters, double and triple tuned filters etc. The appendices give details of thyristor and IGBT valves, transient simulation of converters and DC lines, synchronous generator modeling, SSR analysis, CIGRE Benchmark models and design of DC and AC voltage controls in VSC-HVDC links. Several examples and case studies are included to illustrate the concepts.
