Abstract :
This paper describes the modeling and investigation of the performance of a thyristor controlled series capacitor (TCSC) earned out within the EMTP-ATP program. The TCSC control system was developed using; two different languages supported by EMTP-ATP: Transient Analysis of Control Systems (TACS) and MODELS language. The modeling task is described briefly and some details of the use of the MODELS language are given. The TCSC model is then used to investigate the capability of the TCSC for improving power system performance with respect to: subsynchronous resonance phenomena, fault current limitation, and line current control. Additionally, the innovative POD structure used in an actual TCSC in the Brazilian North-South interconnection is discussed along with some lest results
