Belo Monte Dam Phase II ±800kV UHVDC Transmission Project Successfully Completed System Test

At 5:00 a.m. local time on August 22, 2019, the massive load test of the ±800kV UHV DC transmission project for Belo Monte Dam II of Brazil was successfully completed. So far, the project has completed all system tests and has been provided the conditions for commercial operation.

During the field commissioning, the UHVDC converter valve, DC control & protection system, DC measuring equipment, power grid stability control system and other core equipment supplied by NR have been in good and stable condition.

The Belo Monte Dam (formerly known as Kararaô) is a hydroelectric power plant currently under construction on the Xingu River in the state of Pará, Brazil. The planned installed capacity would be 11,233 MW, which would make it the second-largest hydroelectric dam complex in Brazil and fourth-largest in the world. In Phase II, a ±800kV UHVDC link with distance of 2518km has been built. It will be capable of transporting 4000MW of electricity from hydro power resources in Amazon Valley in the northwest of Brazil to load centers in the southeast part of Brazil, such as Rio De Janeiro and São Paulo.

NR supply scope includes converter valves, UHVDC control and protection system, UHVDC current and voltage measurement equipment and power stability control system. The PCS-8600 UHVDC single pole 12-pulse converter valve is of world’s highest voltage level. It has been certified to international standard by KEMA. The UHVDC control and protection system provides coordination control and shared grounding with existing UHVDC link. The high precise DC measurement equipment and power stability control system will ensure fast step response and safe operation of AC/DC interconnected grids.

NR Electric, as a power stability expert, is a leading power system solution provider across the world. Belo Monte Dam Phase II ± 800kV UHVDC transmission project in Brazil is the first UHV transmission project independently won by the State Grid Corporation of China. The successful implementation of the project has enabled the world's leading Chinese UHV technology to go abroad and will make great contribution to local people constantly.
