Pre-Operational Studies for Telles Pires Plant’s Interconnection

Teles Pires hydroplant, located on the Teles Pires River, on the border of Mato Grosso and Pará states, is part of Teles Pires and Apiacásrivers hydro plants, which formed by the 300 MW Colider, 400 MW Sinop, 700MW San Manuel and230 MW Foz do Apiacásplants. These plants will be integrated into the BIPS by a 500 kV transmission system, which will interconnect the states of Mato Grosso, Goiás and Minas Gerais.

Although the generating units of the Teles Pires plant were made available in 2015, with a delay in the originally planned transmission system, formed by500 kV two circuit between the plant and Ribeirãozinho (MT)substation, it was necessary to use a provisional configuration in the 230 kV Sinop SB for the interconnection to the BIPS. This configuration required specific pre-operational studies, including electromagnetic and electromechanical transient analysis, resulting in important control and protection actions, in order to ensure proper electric performance and the integrity of the transmission and generation equipment.
