This work proposes a model for the HVDC transmission system of the Madeira River Complex, which is developed using PSCAD/EMTDC and based on the design provided by the Energy Research Company (EPE) during the granting concession stage. The implemented model is evaluated by comparing the simulation results and actual data regarding events that occurred in the National Interconnected System (SIN) involving the complex. The Madeira River HVDC system is rated at 7,100 MW, being responsible for transmitting the power generated by the hydropower plants of Santo Antônio and Jirau, which are close to the city of Porto Velho, to local load centers and southeastern Brazil, thus reaching the Araraquara substation in the state of São Paulo through two 2,350 km lines. The system consists of two back-to-back (antiparallel) blocks rated at 400 MW each using capacitor-commutated converter stations in order to supply the load comprising the states of Rondônia and Acre, and also two bipoles of 3,150 MW each, which are constituted by 12-pulse line-commutated current source converters so that power can be transmitted to southeastern Brazil. The results of comparison between actual data and the simulation tests have shown that the percentage difference between the evaluated quantities are within acceptable limits, while it can be concluded that the proposed model is properly validated.
