According to data released by CCTV and the National Energy Administration on November 30, as of the end of October this year, the country's installed renewable energy power generation capacity exceeded 1.4 billion kilowatts, reaching 140.4 billion kilowatts, a year-on-year increase of 208%, accounting for about 49 of the country's power generation units9%。
An important energy hub in the Yangtze River Delta has completed capacity expansion and transformation and has been officially put into operation.
On December 1, the 500 kV Wujiang substation in Suzhou, Jiangsu Province, an important energy hub in the Yangtze River Delta, was completed and put into operation, which further enhanced the clean energy consumption capacity of the Yangtze River Delta region.
The 500 kV Wujiang substation is located in the west of Wujiang District, Suzhou City, and undertakes the important task of connecting clean hydropower from Sichuan to the East China Power Grid. The renovation and expansion project will increase the total capacity of the substation to 6.36 million kVA, which can increase the annual power supply capacity of Suzhou by 6.5 billion kWh, which is equivalent to the electricity consumption of 2 million households for one year.
Zhu Haifeng, a staff member of the Construction Department of State Grid Suzhou Power Supply Company: The Wujiang substation and expansion project has been put into operation, which will strongly support the transmission of clean hydropower from the west to the east, help the clean and low-carbon development of the Yangtze River Delta region, and promote the implementation of the "double carbon" goal.
In the five years since the implementation of the Yangtze River Delta integration strategy, the demand for electricity in East China has continued to grow rapidly in winter. In Jiangsu, the maximum electricity load in winter has increased from 92.76 million kilowatts five years ago to 117.02 million kilowatts, an increase of 2615%。In order to ensure the safety and reliability of power this winter, State Grid Jiangsu Electric Power has comprehensively accelerated the upgrading and transformation of 6 key power grid projects, including Wujiang transformer, involving a substation capacity of 3 million kVA and a line of 896 km.
The stator of the first unit of Yangqu Hydropower Station was successfully hoisted.
The stator is one of the core components of the hydro-generator set, and it is the key equipment that converts mechanical energy into electrical energy. On November 30, the stator of the first unit of Qinghai Yangqu Hydropower Station in the upper reaches of the Yellow River was successfully hoisted, marking a phased victory in the mechanical and electrical installation of the project and laying the foundation for the hydropower station to achieve the goal of putting into operation and power generation in 2024.
The inner diameter of the stator core of this hoisting is 128 meters, outer diameter 15 meters, height 255 meters, by 15More than 70,000 0The 5 mm thick silicon steel sheets were stacked, with a total lifting weight of 520 tons, and the assembly took three and a half months to complete.
Qinghai Yangqu Hydropower Station is the lowest level of the three planned cascade power stations in the upper reaches of the Longyangxia Hydropower Station on the main stream of the Yellow River, with a capacity of 1.2 million kilowatts, and is also an important support peak shaving power supply for Qinghai's clean energy transmission UHV channel. After completion and operation, the average annual power generation is about 473.2 billion kWh, equivalent to saving about 1.66 million tons of standard coal per year.
The construction of a national offshore wind power research and testing base began.
On December 1, China's first national offshore wind power research and testing base started construction in Jiangyin Industrial Park, Fuqing City, Fujian Province. After the completion of the base, it will fill the gap in the test and verification of high-power and full-scale equipment in the field of offshore wind power in China.
The offshore wind power test base is a major project of the national "14th Five-Year Plan", including two parts: an onshore testing center and a test wind farm, and is scheduled to be completed in 2024. After completion, it can carry out the testing and testing of the world's largest capacity wind turbines and the longest size of wind turbine blades, which can strongly support the research and development of offshore wind power equipment and the theoretical research of offshore wind power grid connection in China, help the high-quality development of the offshore wind power industry, and promote the construction of new power systems.
Fang Risheng, Director of the Science and Technology Department of State Grid Fujian Electric Power: The national offshore wind power research and testing base has the ability to analyze, operate and evaluate the characteristics of 25 megawatt and 150-meter wind turbines, and has an important basic role and demonstration effect for breaking through the key core technologies of offshore wind power.
