Power Electronics Converter

A glossary and definition of unified power flow controller (UPFC) related areas, including the structure, equipment, control and protection, test, and maintenance utilized by UPFC are specified in this guide. The guide is applicable in flexible ac transmission system (FACTS) such as UPFC, static synchronous compensator (STATCOM), and static synchronous series compensator (SSSC).

Control architecture for high-power electronics from power semiconductor device levels to the power system level is defined and characterized. Coverage includes the application of power electronics in the areas of Power Quality/Custom Power, Flexible AC Transmission Systems (FACTS), High Voltage DC Transmission (HVDC), Distributed Generation, Energy Storage applications, etc. with a power range from hundreds of kW to thousands of MW, but with emphasis on the 1 MW to hundreds of MW.
