Static transfer switch (STS) model in EMTPWorks RV

Due to the growing requirement for process controls in automated plants, electrical consumers are becoming increasingly more sensitive to the quality and reliability of the power supplies. Thyristor-based static transfer switches (STSs) are able to provide critical loads with a fast transfer to a backup auxiliary source when the main source fails. A static transfer switch model in EMTPWorks RV is developed. Results from three test cases concerning the STS system are presented.
