Alstom's key technology for the energy turnaround and future of very high voltage direct current grids

摘要

Alstom Grid has achieved the best performance ever seen in a High Voltage Direct Current (HVDC) circuit breaker while testing a prototype at Alstom's testing facility in Villeurbanne, France, in presence of an independent expert. In less than 2.5 millisecondsi, the HVDC circuit breaker interrupted currents exceeding 3,000 amperes. These tests were conducted as part of RTE's demonstration activities on the architecture and technologies for DC power grids, within the large scale demonstration project TWENTIES supported by the FP7 programme of the European Commission. In the context of the energy turnaround, these tests, led by RTE, contribute to the development and implementation of new technologies which facilitate the integration of renewable energy sources into the European electrical grid.
