Abstract

The use of fixed series compensation is well known because it provides a lot of benefits to improve the power transfer capacity in transmission lines, as well as power system stability. However, the presence of capacitors in series applied on power transmission system can result in appearance of the subsynchronous resonance phenomena. This technical paper will present the subsynchronous resonance analysis after the installation of 03 (three) fixed series compensations (35 MVAr, 120 MVAr and 37 MVAr) at the Barra do Peixe 230 kV Substation at 230 kV Mato Grosso Transmission System (ELETRONORTE Power Transmission Utility - Brazil). The analysis was carried out using power system simulations realized with PSStrade NETOMAC software. The paper will first describe the methodology used in the analysis, discuss limitations and focus on the possibility of resonance condition on the power transmission system.
