China, April 30, 2024 /PRNewswire/ — Yangzhou- Zhenjiang DC energy tranny project, the initial project to turn in- operation AC transmission lines to DC ones in China, was put into service in eastern China’s Jiangsu Province on Sunday.
State Grid Jiangsu Electric Power Co., Ltd. upgraded the transmission lines between the two locations on different sides of the river to increase the distribution capability of the existing systems without altering the main construction of the cross-Yangtze River transfer buildings.
According to Chen Songtao, planning and management producer with the development department of State Grid Jiangsu Electric Power Co., Ltd., the project proves valuable for areas with a large community but limited space for new network design because related AC-DC alteration technologies can save significant money on long-distance power transmission issues between local power grids.
Six cross-Yangtze River transmission corridors are now used to connect north Jiangsu and south Jiangsu, respectively, by new energy power projects. However, the demand for new power transmissions and stricter environmental protection for the Yangtze River make fresh hall construction less likely, and it is now more important to increase transmission capacity in existing corridors.
The Yangzhou-Zhenjiang transmission lines now have a transmission capability of 1.2 million watt, according to Chen. DC ones of the same energy have greater transmission capacity and lower transfer damage.
AC- DC transmission line conversion has numerous benefits, including high reliance and economic efficiency, in addition to capacity expansion. In particular, Chen cited the cross-Yangtze River section as an example, where its construction cycle was 5 to 6 months shorter than that of building new transmission lines and the associated investment was reduced by nearly 60 million yuan.
State Grid Jiangsu Electric Power saw a significant improvement in efficiency when using smart robots to create highly efficient and environmentally friendly construction. A batch of engineering resolutions for long-distance transmission lines have been changed, according to Xu Huaiyu, vice chief engineer of the project, and nine innovation achievements have been developed independently by the company to facilitate the subsequent construction.
Its transmission capacity is likely to reach 3.60 million kW once phase II and III of the project are finished, further fulfilling the power transmission demand in Jiangsu.
