Abstract

Electromagnetic interference (EMI) may be caused by the fast switching of thyristors and gate turn-off thyristors (GTOs), which are used in static var compensators (SVCs) and static synchronous compensators (STATCOMs) to control reactive power generation and absorption to and from the transmission system. As a result, high levels of electrical disturbance may be coupled into the electrical ports of auxiliary electronic equipment, and if the levels are above the immunity level of the equipment, maloperation that may lead to a trip can occur. This study sought to measure typical conducted EMI levels in four selected SVC-based and one static synchronous compensator (STATCOM)-based substation. The results and their correlation to the existing IEC 61000-4 EMC Standards series are discussed, and indications of changes to the immunity tests are presented.
