Juan Fernando Piñeros, Javier Ferney Llano, Felix Humberto Montaño, German Gutierrez, Timo Rivera This work presents the analysis and lessons learned from a real single phase power swing phenomenon in an area of the 230 kV transmission network of the Colombia power system. This phenomenon was caused by the asymmetrical connection to the power system of four power hydro generators in a 1200 MW power plant by the connection in the high side of their step up transformers only with the phase C to the power system because of a failure in the closing process of a disconnector at the power plant substation
