CURENT Power and Energy Industry Seminar – Dr. Pratap Mysore

Date:  Friday, October 26, 2018

Time:  12:20 – 1:10pm EST

Location: 404 Min H. Kao Building

Title: Protection and Control Issues associated with Shunt Compensated Transmission Lines

Presenter: Dr. Pratap Mysore, Pratap Consulting services, LLC

Abstract: Shunt reactors are installed in Transmission System to maintain the system voltage within permissible limits during light load conditions. Their connection to the system may vary but, the line connected reactors provide more economical installation over connecting them in standard positions on buses.  The presentation discusses switching issues associated with Shunt compensated lines (lines with shunt reactors on the lines) due to the presence of DC offsets in line currents. The presentation provides basic concepts that lead to delayed current zeros resulting in line breaker failures. Presentation covers various mitigation methods used in the industry to prevent breaker failures.  It also discusses protection and controls used in fault clearing and restoration.
