1、With the world's first "super cable" running at full capacity for the first time this summer, Shanghai formed an industrial alliance around superconducting cable innovation
This summer, the world's first 35kV km-level superconducting transmission demonstration project achieved full load operation for the first time, setting a new record for the maximum actual operating capacity of commercial superconducting transmission projects in China. Shanghai Cable Research Institute subordinated to Shenneng, the core technical team of independent research and development of this project, has worked hard by three generations of engineers for 20 years, and the dream of superconducting cable has been finally realized in Shanghai.
Superconducting transmission is one of the most revolutionary frontier technologies in power industry. Compared with conventional cables of the same specification, HTS cables boast the advantages of small size, light weight, low loss, large transmission capacity and environmental protection. If HTS cables are widely used, it will solve the problems of high power density and shortage of construction land in super-large cities like Shanghai.
Shanghai Cable Research Institute took the lead in forming a superconducting industry alliance with the Institute of Computing Technology of Chinese Academy of Sciences, Shanghai Jiao Tong University, Shanghai University, State Online Shanghai Electric Power Company and other organizations engaged in superconducting materials research, shaping a set of mechanism and ecology that is market-oriented, supported by the government and innovated around the industrial chain layout, successfully integrating resources from all parties and stimulating market vitality.
On December 22nd, 2021, the world's first fully commercial demonstration project of 35kV km-level superconducting cable was officially put into operation at Xuhui District, Shanghai, with the total length of 1.2 kilometers. At present, it has been running safely and stably for more than 600 days continuously, setting a precedent for the operation of kilometer-class superconducting cables in the core areas of large cities.
2、Since the "14th Five-Year Plan", Shanghai's high-quality development has steadily improved, and six indicators have reached the planning targets ahead of schedule
On November 22nd, the 8th Meeting of the Standing Committee of the 16th Shanghai Municipal People's Congress heard and reviewed the mid-term evaluation report on the implementation of the 14th Five-Year Plan for National Economic and Social Development of Shanghai and the Outline of Long-term Goals in 2035. It is reported that the 20 major indicators identified in the Outline have made good progress on the whole. As of June 30th, 2023, six indicators have reached the planning targets ahead of schedule. Generally speaking, it presents three characteristics.
First, high-quality development has steadily improved. In 2021, Shanghai's GDP exceeded 4 trillion yuan, reaching 4.47 trillion yuan in 2022, and the per capita GDP exceeded 180,000 yuan, reaching the level of moderately developed economies. The proportion of digital economy in GDP increased to 60.5%, the total transaction volume in financial market reached 2,933 trillion yuan, and the number of high-value invention patents per 10,000 population reached 40.9.
Second, high-quality life continued to advance. The per capita disposable income of residents increased by 5% annually, which was faster than the economic growth level and reached 79,610 yuan. The renovation of second-class houses below the old buildings in the downtown was completed ahead of schedule. The proportion of the main working-age population with higher education reached 55.3%.
And third, high-efficiency governance has been continuously strengthened. The proportion of surface water reaching or better than Class III water body is 95.6%, far exceeding the planning target of 60%. PM2.5, NO2 and PM10 all dropped to the lowest level since the monitoring record was recorded, and PM2.5 reached 25 μg/m3. The recycling rate of domestic garbage reached 42%, and the forest coverage rate reached 18.5%, both of which were better than expected.
