HVDC Light® (自励式)



欧州内各国の相互接続と世界へ向けて

日立エナジーのHVDC Lightは、VSC技術(自励式変換器)に基づき、地中や水中、長距離の送電を行うために設計されています。”見えない "送電線、より少ない電磁場、オイルフリーケーブル、コンパクトな変換所など、環境面でも多くのメリットを提供します。

HVDC Lightは、HVDC送電の経済的な送電容量の範囲を数十メガワット (MW) まで拡張する(低下させる)技術です。この技術による送電可能容量の上限は、現在3,000 MWと±640 kVに達しており、数百万世帯に電力を供給し、2,000km以上の送電を可能にします。また、このシステム設計は、洋上風力発電や相互接続などのアプリケーションで大きな強みとなるコンパクトな変換所を実現します。

What is HVDC Light®?


HVDC Light® is quick to install and provides an alternative to conventional AC transmission systems and local generation in several cases, such as:

  • Connecting wind farms to the onshore grids
  • Underground power links
  • Providing shore power supplies to islands and offshore oil & gas platforms
  • Connecting asynchronous grids
  • City center infeed

Utilities are under extreme pressure to meet consumer and regulatory demands for a high-quality, competitively priced power supply that has a low environmental impact. The expansion of AC transmission capacity is often limited by local planning regulations and the concerns of local residents who object to the installation of new overhead lines. 

Why Hitachi Energy's HVDC?


It is now economically feasible to expand transmission capacity using Hitachi Energy's HVDC cables. This approach not only minimizes environmental impact but also improves the quality of the power supply.
