How Will China's Power Equipment Develop In The Next Decade?

- Oct 18, 2018-

After more than 30 years of reform and opening up, especially in the past 10 years, China's power equipment manufacturing industry has undergone earth-shaking changes, forming an industrial system with complete categories, large scale and certain technical level.

(1) The output of power equipment ranks first in the world

Since 2006, China's annual output of power generation equipment has exceeded 100 million kilowatts for 9 consecutive years, accounting for more than 50% of global power generation equipment production. By the end of 2014, China's power generation equipment installed capacity was 1.36 billion kilowatts, surpassing the United States in the world. .

Since 2008, the annual output of transformers has exceeded 1 billion kVA for 7 consecutive years, and the length of transmission lines of 220 kV and above is 579,900 km, ranking first in the world.

China has now become a veritable power equipment manufacturing country. In 2014, the total industrial output value of the power equipment manufacturing industry exceeded 5 trillion yuan, the main business income was 5.33 trillion yuan, the profit was 311.2 billion yuan, and the total import and export volume was 164.9 billion US dollars.

(2) The technical level of power equipment continues to improve

The electric power equipment represented by large-scale power generation complete sets of equipment, ultra-high-voltage power transmission and transformation complete sets of equipment, and smart power grid complete sets of equipment with independent intellectual property rights has reached the international leading level. Among them, the marked major technical equipments and products include:

Power generation equipment: 1000 MW ultra-supercritical thermal power units, 700 MW and above hydropower units, 1000 MW nuclear power units, etc.; 300 MW F-class heavy-duty gas turbines.

Power transmission and transformation equipment: 1000 kV UHV AC transmission complete sets of equipment, ±800 kV UHV DC transmission complete sets of equipment, smart grid power transmission and transformation complete sets of equipment.

Key core components: safety valves for ultra-supercritical thermal power units and large nuclear power units, protective circuit breakers for large generator sets, 5-inch 7200 volts/3000 amps, 6-inch 8500 volts/4000-4750 ampere-controlled thyristors, 5 inches 7500 Volt/3125 amp light control thyristor, ±800 kV and below voltage level DC transmission converter valve.

(3) The ability of power equipment to support the construction of major national projects has been significantly enhanced

After more than 30 years of unremitting efforts, we have adhered to the combination of "production, learning, research and use", and through the introduction of technology to absorb and re-innovate, China has successfully developed a number of power equipment suitable for China's national conditions and international leading.

It has been applied to 600MW supercritical thermal power project in Hebei North, 10000 MW ultra-supercritical thermal power project in Zhejiang Yuhuan, 1000MW ultra-supercritical air-cooled thermal power project in Ningxia Lingwu, Sichuan Baima ultra-supercritical circulating fluidized bed project, Three Gorges Hydropower Project, Xiluodu Hydropower Project, Xiangjiaba Hydropower Project, Ling'ao Phase II Nuclear Power Project, Sanmen Nuclear Power Project, Guanting-Lanzhou East ±750 kV AC Transmission and Transformation Project, Jindongnan-Nanyang-Jingmen 1000 kV UHV Exchange Transmission projects, Yunnan-Guangdong ±800 kV UHV DC transmission project, Xiangjiaba-Shanghai ±800 kV UHV DC transmission project and other major national projects have effectively ensured the national “West-East Power Transmission” energy strategy. Successful implementation.
