Open Access research with a European policy impact...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of Open Access research papers by Strathclyde researchers, including by researchers from the European Policies Research Centre (EPRC).

EPRC is a leading institute in Europe for comparative research on public policy, with a particular focus on regional development policies. Spanning 30 European countries, EPRC research programmes have a strong emphasis on applied research and knowledge exchange, including the provision of policy advice to EU institutions and national and sub-national government authorities throughout Europe.

Abstract

Transient electromagnetic (EM) emissions are generated when thyristor or gate turn-off thyristor (GTO) valves are being switched on and off within substations installed with static var compensators (SVCs) and static synchronous compensators (STATCOMs). These emissions may cause malfunction of, or damage to, electronic equipment positioned nearby without appropriate protection. Four SVC-based substations and one STATCOM-based substation were selected for electromagnetic-interference (EMI) measurement, analysis, and evaluation. A comparison was made between the radiated EMI features from each. The analyzed results were correlated to the present electromagnetic-compatibility standards, and recommendations of changes for immunity tests were presented specifically for flexible ac transmission system (FACTS)-based radiated EMI. Preliminary analysis was also given to the causes of FACTS-based EMI, which indicated that valve switching behavior and the stray parameters of FACTS equipment layout were the main contributors to high-frequency-radiated interference.
