According to Baoding Tianwei Electric Co., Ltd. changed the news, at 0:00 on July 15, China's second largest hydropower station - Xiluodu Hydropower Station's first unit (13F) formally grid-connected, Tianwei change to the unit developed by the supporting USSP The operating status of the -860MVA / 500kV main transformer is good, marking the first official launch of the world's first three-phase combined generator main transformer with the largest capacity and the highest voltage rating. It is understood that the Xiluodu hydropower station is located in the Leping County of Sichuan Province and the mainstream of the Jinsha River in Yunnan Yongshan County, is the backbone of the implementation of the "west to east" strategy of power supply, set the left and right sides of the underground plant, the installation of nine hydrogenerators , Designed installed capacity of 12.6 million kilowatts, installed capacity in the country after the Three Gorges Hydropower Station. After the completion of the Xiluodu Hydropower Station, the annual generating capacity will reach 64 billion kilowatt-hours, equivalent to reducing 41 million tons of coal annually, reducing carbon dioxide emissions by 150 million tons, reducing nitrogen dioxide emissions by 480,000 tons and reducing sulfur dioxide emissions by nearly 850,000 tons. In September 2009, in the Xiluodu Hydropower Station 550kV transformer bidding, Tianwei changed its warranty to all 10 860MVA / 500kV combined main transformers of the right bank power station. In the process of development, Tianwei changed the world's leading transformer verification analysis software, the calculation results were electromagnetic field, wave process, short-circuit mechanical force, temperature rise, oil flow distribution verification analysis to solve the large capacity transformer product structure Local overheating problems, the product has a small loss, low noise and other significant advantages, to ensure long-term product safety and stability. In May 2012, the first batch of 3 USSP-860MVA / 500kV main transformers to be commissioned by Tianwei Insurance for the Right Bank Power Station of the Luodu Hydropower Station was successfully delivered. Products using three-phase combination of split transportation, on-site assembly, three in one way, not only for the transport of products to find a successful solution, but also to reduce the amount of earthwork and reduce project costs. Up to now, Tianwei Warranty Change has been completed according to the contract to complete six sets of Xiluodu Hydropower Station USSP-860MVA / 500kV main transformer. Since July 2013, Tianwei has independently developed the transformer in China's "Xinjiang Power Transmission" strategic priority project --- Xinjiang and Northwest main network 750 kV second channel project, Hebei South Network's first 500 kV smart substation, power company Hebei Yuanshi summer peaks key projects --- 500kV substation and other transmission and transformation focus electrician Chengzhong Shun Lee put into operation for the Xiangjiaba - ± Shanghai 800 kV HVDC transmission demonstration project for the system Of the converter transformer to achieve safe and stable operation of the 3rd anniversary of China's third largest hydropower station Xiangjiaba hydropower right bank power station independently developed 4 SSP-890MVA / 500kV water-cooled main transformer unit by the first full load test run, first-class product quality by the vast The user's high opinion.
