Keeping the Power Flowing: A Commitment Throughout the HVdc and FACTS Life Cycles

摘要

An increasing number of high-voltage dc (HVdc) transmission links are being built around the world to efficiently and cost-effectively move large amounts of power from generation sites to distant centers of consumption. (Figure 1 shows a typical HVdc installation.) Similarly, flexible alternative current transmission systems (FACTSs) are increasingly being employed to boost power capacity and improve stability in existing grids the world over. These installations represent significant investments for owners, so it is essential that they are maintained in good condition with proper service strategies, onsite and remote maintenance, proper training of maintenance personnel, and, finally, after many years of successful operation, with upgrades to some parts of the installation.
