Service Energy, Rio Engano 20MW project

(Brazil)


Customer Profile
The end customer is Service Energy, an independent power producer coming from the construction business in Brazil.
They are developping small hydro project in Brazil.

The Engano project consists in 4 small hydro power plant on the Rio Engano river in Angelina, Santa Catarina state (south of Brazil) summing 16MW installed power.
  • Barra Clara plant (in operation) : 1 x 2MW Kaplan turbine, 20m net head height
  • Santa Ana plant (in operation): 2 x 3MW Francis turbine, 70m net head height, 2,5km tunnel and 660m open canal
  • Coqueiral plant (civil work under construction): 2 x 2MW Francis turbine, 40m net head height
  • Fartura plant (not started yet): 2 x 2MW Francis turbine, 60m net head height

These 4 plants are connected to a single supervision Scada system. The goal is to operate the 4 plants from 1 single control room based in Santa Ana plant.
The plants generate power in 4,5kV. Then each plant is connected to a 34,5kV line through a MV/MV outdoor substation.
The 34,5kV line is connected to 138kV HV line through the MV/HV step-up automated substation.

For Schneider Electric, the project consists in engineering, installation and commissioning of:
  • the 4 small hydro plants (supervision, control, electrical distribution and grid connection)
  • the Scada system to supervise the 4 plants remotely
  • the automation of 1 MV/HV step-up substation
