The Research of Influence of TCPST on Subsynchronous Oscillation Based on Complex Torque Coefficient Method

In recent years, more and more Flexible AC Transmission System (FACTS) devices have been used in power systems, making subsynchronous oscillation (SSO) more and more serious. Thyristor Controlled Phase Shifting Transformer (TCPST), as an advanced FACTS device, can alleviate SSO effectively. In this paper, PSCAD is used to build the transient model of the second standard test system with TCPST, and...
