Basic situation of China Southern Power Grid
China Southern Power Grid covers five provinces and regions, and is connected with the power grids of Hong Kong, Macao and Southeast Asian countries, with a power supply area of 6,543,800 square kilometers. The power supply population is 252 million and the power supply customers are 84.97 million. In 20 17 years, the maximum load of the whole network was 65438+63 million kilowatts, an increase of10.5%; The electricity consumption of the whole society1073.3 billion kwh, up by 7.2%.
The east-west span of China Southern Power Grid is nearly 2,000 kilometers, and there are various power sources such as water, coal, nuclear power, pumped storage, oil, gas and wind power. By the end of 2065,438+07, the total installed capacity of the whole network was 3 1 100 million kilowatts (including thermal power 65.438+500 million kilowatts, hydropower 65.438+200 million kilowatts and nuclear power 654.48 billion kilowatts). 1 10 kV and above substations have a capacity of 880 million KVA and a total length of 220,000 kilometers.
By the end of 20 17, the installed capacity and power generation of non-fossil energy in the whole network accounted for 50.8% and 50.2% respectively, and the power generation accounted for nearly twice the national average.
China Southern Power Grid is connected with AC and DC in series, with long distance, large capacity and ultra-high voltage transmission, which has complex safety and stability characteristics, great driving difficulty and high technology content. The company has achieved a number of internationally advanced scientific research achievements with independent intellectual property rights in power grid security and stability control technology, power grid economic operation technology and equipment integration application technology, among which the achievement of "UHV±800 kV DC transmission project" won the 20 17 National Science and Technology Progress Special Award, which indicates that China Southern Power Grid is in a leading position in the field of UHV transmission.
China Southern Power Grid is the power grid with the largest scale, the best comprehensive social benefits and the strongest development potential.
At present, the power transmission from west to east has formed "eight alternating currents and ten direct currents" (500 kV, four alternating currents in the sky, four alternating currents in Guangzhou and four alternating currents in Guiyang; 500 kV Tianguang DC, Sanguang DC and Jinzhong DC each 1 time, Xiluodu DC twice to Guangdong DC and Guiguang DC twice, 800 kV Guang Yun UHV DC, Nuozhadu DC to Guangdong UHV DC, Northwest Yunnan DC to Guangdong UHV DC each 1 time) 500 kV and above large passages 18.
China Southern Power Grid is the first "going out" power grid in China. As the Chinese executive unit of the Greater Mekong Subregion power cooperation determined by the State Council, the company actively implements the "Belt and Road Initiative" and strengthens power cooperation with countries in the Greater Mekong Subregion and Hong Kong and Macao. In 20 17, the electricity sent to Hong Kong through China Southern Power Grid accounted for 28.8% of its electricity consumption; The electricity sent to Macao accounts for 73.5% of its electricity consumption.
By the end of 20 17, the company had sent 33.578 billion kwh of electricity to Vietnam,105.5 billion kwh to Laos and imported1554.7 billion kwh from Myanmar.
The main situation of production and operation since the establishment of the company.
From 2003 to 20 17, the company's electricity sales increased from 257.5 billion kwh to 890.2 billion kwh, with an average annual increase of 9.3%. Operating income increased from 129 billion yuan to 491900 million yuan, with an average annual growth of10.0%; Power transmission from west to east increased from 26.7 billion kWh to 202.8 billion kWh, with an average annual growth rate of 15.6%. Total assets increased from 2.3/kloc-0.20 billion yuan to 744.5 billion yuan, a two-fold increase; Accumulated profits and taxes reached 469,654.38 billion yuan.
The capacity of substations of the whole network 1 10KV and above increased from 200 million KVA to 880 million KVA, and the line length increased from 73,000 km to 220,000 km, increasing by 3.4 times and 2 times respectively. The company was rated as Grade A in the annual performance appraisal of the State Council SAAC12. 14 has been ranked among the top 500 enterprises in the world, and now it ranks 1 10.
2018-1-August, the electricity consumption of the whole society in five southern provinces and regions was 759.5 billion kwh, up by 10.2% year-on-year, of which Guangdong Province was 422.7 billion kwh, up by 8.5%. Guangxi was 654.38+0096 billion kWh, an increase of 20.8%; Yunnan Province was 654.38+0039 billion kWh, an increase of 9.2%; 94.2 billion kWh in Guizhou Province, up by 7.7%; Hainan's 21600 million kwh, an increase of 6.9%.
