截至2015年6月18日,世界首条±800千伏特高压直流工程--云南至广东特高压直流输电示范工程双极安全投产5年,送广东电量累计突破1200亿千瓦时,达1206亿千瓦时,对优化东西部资源配置、实现区域互利共赢、促进节能减排起到了积极作用。该工程是国家“十一五”重点工程和特高压直流输电自主化示范工程,西起云南楚雄州,东至广东增城,输电容量500万千瓦,输电距离1373公里。工程综合自主化率达到
As of June 18, 2015, the world’s first ±800 kV UHV DC project - Yunnan-Guangdong UHV DC transmission demonstration project bi-polar safety put into operation for 5 years, sending Guangdong electricity has exceeded 120 billion kwh, reaching 120.6 billion kilowatts At the same time, it played a positive role in optimizing the allocation of resources in the eastern and western regions, realizing regional mutual benefit, and promoting energy conservation and emission reduction. The project is a national “Eleventh Five-Year” key project and demonstration project for UHV DC transmission automation. It starts from Chuxiong Prefecture in Yunnan and Zengcheng in Guangdong in the east, with a transmission capacity of 5 million kilowatts and a transmission distance of 1,373 kilometers. The comprehensive autonomy of the project has been achieved
