Neoenergia starts energizing the Fernão Dias substation
A substation works as a switching point and load management, and the energy can be directed to various locations in the city or state, including changing the voltage of the load, to higher or lower, depending on the need for distribution. It concentrates several automated equipment that act to protect the electrical system, avoiding failures, overloads and problems that may affect the final consumer.
In a scenario of heavy load or shutdown, the Static Reactive Power Compensator (CER) in Fernão Dias allows the North and Northeast regions to export energy from the Belo Monte hydroelectric system to the Southeast. Thus, CER ensures a more stable, reliable and quality energy transmission to the Southeast region, the largest industrial park in the country.
The substation is fully automated, with an integrated system of supervision, command, control and protection, eliminating the presence of electricians and operators to carry out switching. These operations are carried out by Neoenergia's central operation center, in Rio de Janeiro, by means of satellite communication. In addition to improving the system's reliability, employees are able to act more quickly and assertively during possible events.
