HVDC historyHistory and Introduction

First commercial HVDC transmission in 1954(100 kV, 20 MW)

HVDC characteristics

Why use HVDC instead of AC?

DC Decreases total cost for long distance power transmission with overhead lines and/or cables.DC enables connection between asynchronous AC networks.Gives fast and accurate control of the power flow.

The two Back-to-back blocks are each rated 400 MW, although maximum powertransmission into the 230kV is limited to 600 MW due to the weakness of the system.In the system studied by EPE and defined as the “Basic Configuration” in thedocuments issued by ANEEL for the transmission concession auction [2], the 230 kVside is strengthened by three 100 Mvar synchronous compensators. ABB offered asolution using CCC converters for the Back-to-back, the only major deviation from thesuggested Basic Configuration.


The two back-to-back blocks are each rated 400 MW, although maximum power transmission into the 230kV is limited to 600 MW, at least until 2017. To overcome the problems of feeding into such a weak system, the back-to-back uses Capacitor Commutated Converters (CCC), improving not only performance related to commutation failures, but also reducing the need for shunt reactive compensation. Although not strictly necessary from a performance point of view the 500 kV side of the back-to-back also uses CCC technology. This permits use of harmonic filters with a relatively low Mvar rating on both sides of these converters.

Sistema de Conexão Acre – Rondônia : Back-to-Back com CCC


Operating modes

The back-to-back has to operate in various considerably different configurations of the network:

1. Feeding weak 230 kV network synchronous with the Brazilian network.

2. As normal operation, but with a large gas fired thermal unit in operation locally in Porto Velho.

3. As normal operation initially, but separating from the Brazilian System (Isolated operation).

4. Start-up in isolated operation (Black start).

5. Feeding 500 kV converter bus from 230 kV (Reverse power direction).
