BEIJING, April 16 (Xinhua) -- The Yangzhou-Zhenjiang ±200 kV embedded HVDC power transmission project (phase one) has recently successfully passed the full-capacity test, with all indicators meeting expected requirements, according to the State Grid Jiangsu Electric Power Co., Ltd on Tuesday.
The project, located in east China's Jiangsu Province, will be carried out in three phases. It is designed with a total transmission capacity of 3.6 GW (1.2 GW per phase). Upon completion, it will enormously enhance the power transmission capability across the Yangtze River within Jiangsu power system.
Earlier, State Grid Jiangsu Electric Power Co., Ltd. proposed an "embedded" hybrid AC-DC interconnection scheme. The project is the first-ever one in the country to transform existing AC lines into DC lines, a process known as "AC-to-DC conversion".
It is noted that the project introduces innovative hybrid interconnections of "embedded" DC lines with existing AC lines over the Yangtze River, which will greatly improve the power transmission capability and the comprehensive benefits of the power grid, and help achieve the use of clean energy in the Province.
