The maximum transmission capacity of 7.2 million kilowatts, equivalent to 40% of the current electricity consumption in Suzhou, will greatly ease the use of pressure
The 1000-kilovolt Kunshan substation project has completed the feasibility study review, which can completely change the tension of electricity consumption after being put into operation.
This year, the Suzhou area network is expected to have a load of 18 million kilowatts. In extreme cases, the electricity supply gap will reach 3.8 million kilowatts. Yesterday, Suzhou Power Supply Company announced that the ±800 kV Jinping-Sulan UHVDC power transmission line project will be put into operation before summer in June next year. Its maximum transmission capacity is 7.2 million kilowatts, equivalent to the current electricity consumption in Suzhou. 40% can greatly ease the use of electric power in Sioux City, which will also be the largest long-distance “point-to-point†input external power in Suzhou history. Vice Mayor Pu Rongzhen investigated the site of the UHV project.
According to reports, in order to fundamentally solve the problem of power shortage in our city, in 2008, our city responded to the national grid special high voltage engineering plan and successively established “four lines and two stations†in Suzhou, which are ±800 kV Xiangjiaba—Shanghai. UHV DC demonstration project (currently commissioned), ±800 kV Jinping-Sulan UHVDC transmission line project (Jinsu line for short), 1000-kilovolt Huainan-Funan-Zhebei-Shanghai UHV AC transmission line Engineering, 1000 kV Huainan - Nanjing - Taizhou - Suzhou - Shanghai UHV power transmission project, ± 800 kV Tongli converter station, 1000 kV Kunshan substation. Among them, the Jinsu Line (located at the Tongli Converter Station) and the 1,000-kV Kunshan substation will provide direct electricity support to Suzhou.
This reporter learned that Jinsu line uses a ± 800 kV UHV DC transmission, transmission capacity of 7.2 million kilowatts, a total investment of 22.24 billion yuan. The starting point of the project is Xichang, Sichuan. The total length of the line is about 2,095 kilometers. It passes through six towns and cities in Taoyuan, Zhenze, Qidu, Hengfan, Pingwang and Songling in Wujiang City. It involves a total of 94 bases in Taki and landed at Tongli Converter Station. Yesterday, the reporter saw at the site of the Tongli Converter Station project at the junction of Songling Town and Pingwang Town. Most of the civil works were completed and gradually entered the electrical installation stage. According to the person in charge of the project, the Tongli Converter Station covers an area of ​​approximately 16.67 hectares. The scale of construction is one DC double-pole line, six 500-kV line appearances, two return journeys to Suzhou West, and three return journeys to Wujiang. The car workshop changed its direction one time. It was completed once in six times in this period. Tongli converter station took a step-down of the UHV current.
Relevant person in charge of the Suzhou Power Supply Company stated that the Jinsu line belongs to ultra-long-distance “point-to-point†transmission, with no shunt in the middle and low loss. The transmission capacity in the early stage can reach 200 to 3 million kilowatts, and it can reach 7.2 million kilowatts at full supply. It is equivalent to 40% of the current electricity consumption in Suzhou, which can greatly ease the use of electric power and will be put into operation before summer in June next year. To completely change the tension in Suzhou, it is necessary to wait until the 1000-kilovolt Huainan-Nanjing-Taizhou-Suzhou-Shanghai UHV power transmission project is put into operation, and the 1,000-kilovolt Kunshan substation at one of the halfway stations will bring power to the Suzhou Power Grid. Another source of constant external current. At present, the project has also completed feasibility review.
