Xiamen Island VSC-HVDC Demonstration Project

Description

On August 4, 2014, C-EPRI was awarded the Xiamen Island VSC-HVDC Demonstration Project by State Grid Corporation of China (SGCC), the largest utility in the world.

Xiamen Island is the main part of Xiamen City in Southeast China’ s Fujian Province, and has high requirement for power quality and reliability. Currently, the Island is mainly powered by three 220kV AC lines. However, with the rapid development of economy in this area, the existing network is looming with growing power deficit.

C-EPRI’s solution is to transmit electricity from Xiamen mainland to Xiamen Island, using its latest ±320kV/1000MW VSC-HVDC technology. It employs a bipolar configuration and has the highest capacity and voltage ratings worldwide, with two converter stations linked via 10.7km XLPE subsea cables. C-EPRI is responsible for the design, engineering, supply, installation and commissioning of key converter station equipment. Commercial operation of the project is scheduled for the end of 2015.

The winning of the bid not only reinforces C-EPRI’s leading position in the Chinese market, but also builds up its confidence to tap further into the international market.
