ABSTRACT

High-voltage power electronic substations consist essentially of the main power electronic equipment, that is, converter valves and FACTS controllers with their dedicated control and protection systems, including auxiliaries. Furthermore, in addition to the familiar components of conventional substations covered in the preceding sections, there are also converter transformers and reactive power
