Xiluodu Hydropower Station is located in the Xiluodu valley section of Leibo County in Sichuan Province and Yongshan County in Yunnan Province. It is the largest of the four giant hydropower stations in the lower reaches of the Jinsha River, with a total installed capacity of 14.4 million kilowatts and the third highest power generation in the world. It is the second largest hydropower plant in China.
The reporter learned from the relevant department of the Jinhua Electric Power Bureau that the Xiluodu Hydropower Station clean hydropower is expected to be sent east to Zhejiang in 2014 through UHV DC transmission lines.
It is understood that during the "12th Five-Year Plan" period, Zhejiang will maintain an annual economic growth of around 8%, and the average annual growth rate of Jinhua's peak load will exceed 9%. If you do not consider the power input outside the zone, it is expected that the electricity gap in Zhejiang will reach 20 million kilowatts by 2015. After the electricity supply and use balance across the province, the gap in Jinhua power will be about 2 million kilowatts.
However, due to the large number of people in Zhejiang Province, a lack of conventional energy resources, power supply construction is limited by site resources, transportation conditions, environmental protection requirements, etc. Jinhua is subject to more objective restrictions due to its depth in Zhejiang Province.
“UHV power grids have the characteristics of large-capacity, long-distance, low-loss power transmission and land resource conservation. The construction of ultra-high voltage power grids can, on the one hand, change the current energy input method solely based on coal-to-coal shipments and realize coal transmission and transmission. At the same time, it can effectively relieve the pressure on energy transportation in our province. On the other hand, it can reduce the increase of new coal-fired generating units in the province, thereby reducing the emission of sulfur dioxide and greenhouse gases and alleviating the environmental pressure in our province.†Chen Zhenxin, deputy director of Jinhua Electric Power Bureau Introduction.
The development of UHV power grids has been included in the national energy development strategy, national long-term science and technology development plan, and China's national plan for addressing climate change. It is to build a stable, economical, clean, and safe energy supply system in Zhejiang, optimize energy structure, and promote economic transformation and upgrading. Other aspects have an important role in promoting.
Xiluodu-Zhesi±800kV UHV DC transmission project is a national heavy-duty power grid project that implements the “West-to-East Electricity Transmission†strategy and optimizes the allocation of resources throughout the country. The project has a transmission distance of 1688.4 km and adopts a ±800 kV direct current transmission scheme. The system has a transmission capacity of 7.5 million kilowatts, starting from Xiluodu in the west and west of Zhejiang in the east, passing through Sichuan, Guizhou, Hunan, Jiangxi and Zhejiang provinces. Among them, a new Zhejiang West Converter Station is built in Zhejiang Province. The route passes through Jiangshan County, Qujiang District, Kecheng District, Longyou County, Quzhou City, Wucheng District and Wuyi County of Jinhua City.
On March 15, Xiluodu-Zhexi ± 800kv UHVDC transmission project, Zhejiang West Converter Station site, Zhejiang section route program passed the provincial experts. From the review meeting, it was learned that the West Zhejiang Converter Station was located at Jinhua Wuyi and the project was started at the end of the year. It was planned to be completed by the end of 2013 and formally put into operation in 2014.
After the project is put into operation, Xiluodu Power Station will become the backbone of the national “West-to-East Power Transmission†strategy, and Jinhua will become the central hub of the national West-to-East power transmission, playing an important role in realizing the rational allocation of energy resources, improving power supply, and improving the ecological environment in China. effect.
It is understood that the West Zhejiang (Wuyi) converter station covers an area of ​​about 22 hectares, with an investment of nearly 6.4 billion, a total capacity of 7.5 million kilowatts, a total of 36,600 kVA transfor- mation, 28 sets, and a long-range 500 kV AC outlet 10 times. It is planned to be put into operation in 2014.
