HVDC Transmission and FACTS Fundamentals

This panel session introduces fundamental concepts of both HDVC transmission and Flexible AC Transmission Systems (FACTS) controllers. There has been a renewed intrerest in the application of HVDC transmission schemes in recent years for applications including back-to-back converters, bulk power transfer, and offshore wind applications, as well as proposals for HVDC grids. In addition, applications requiring dynamic reactive compensation utilizing FACTS controllers have been increasing. Reactive compensation is often used to improve voltage regulation or to enhance power transfer. In many cases, reactive compensation using fixed or mechanically switched capacitors is sufficient, but some applications require the reactive compensation to vary dynamically using FACTS devices. The presentations in this session are tutorial in nature and do not presume familiarity with power electronics. It is intended to provide the background material that enables attendees to proceed to the more technically advanced presentations in this conference.
