The History and Development of China Electric Power

Overview of electric power development

I. History of power system development (I) History of power system development China power system was gradually formed with the development of China power industry, and its development can be divided into the following three stages. (1)1882 ~1937.1882 On July 26th, the first 12 unit in Shanghai generated electricity. On the eve of the War of Resistance against Japanese Aggression outbreak in 1936, there were 46/kloc power plants in China. (2)1937 ~1949.1937 After War of Resistance against Japanese Aggression started, power plants in coastal cities such as Jiangsu and Zhejiang were destroyed or moved to the rear; In order to meet the needs of the war, the power industry in southwest China has developed to a certain extent. Japanese imperialism, based in the northeast, produced and supplied munitions for the war, thus making the northeast power system develop to a certain extent. 1949 when People's Republic of China (PRC) was founded, the national installed power generation capacity was 1848.6, and the annual power generation was about 4.3 billion kW·h, ranking 25th in the world. At that time, the power system that had been formed in China was as follows: ① the power system in the middle part of Northeast China, centering on Fengman Hydropower Station, connected Shenyang, Fushun, Changchun, Jilin and Harbin with 154kV transmission lines; (2) The power system in the southeast of Northeast China, with Shuifeng Hydropower Station as the center, adopts 220kV and 154kV transmission lines, bordering on Dalian, Anshan, Dandong, Yingkou and other power supply areas; (3) The northeast eastern power system, with Jingbohu Hydropower Plant as the center, uses 1 10kV transmission lines to connect Jixi, Mudanjiang, Yanbian and other power supply areas; ④ Hebei northern power system, connecting power supply areas and power plants such as Beijing, Tianjin and Tangshan with 77kV transmission lines. Includes the following power system. China's power system dispatching automation began in 2000.
