Under the €20m contract, the company will provide its flexible AC transmission systems (FACTS) along with overall project management, including equipment, civil works, electromechanical assembly, design, management, supervision of erection and commissioning.
Specifically, the company will supply a Static VAr Compensator (SVC) with a power rating of -200/300 MVAr, and network connection equipment with nominal voltage of 500 kV for the Bom Despacho substation project.
The scope of equipment supply for the Sao Gotardo substation includes a shunt capacitor bank connected to the 345 kV network, along with a nominal power of 150 MVAr, and the network connection equipment.
Alstom Grid Brazil and Latin America Power Electronics business director Marco Finoti said the company has installed the highest rated Static VAr Compensator in Brazil.
”The objective is to enhance power quality at the Bom Despacho substation – a major hub in Cemig’s transmission system – using our state-of-the-art FACTS technology,” Finoti added.
Work on the Sao Gotardo and Bom Despacho projects is scheduled to complete within one year and 18 months respectively.
Alstom Grid had originally supplied and delivered the Bom Despacho substation to Cemig in 2004.
