China's electric power technology level has entered the world's advanced ranks

On May 20, the 10th member congress of the Chinese Society of Electrical Engineering was held
in Beijing.
Shu Yinbiao, General Manager of State Grid Corporation of China and Acting Chairman of the 9th China Society of Electrical Engineering, made a report
on the work of the 9th Council.

The report believes that in the past five years, China's power industry has maintained a good momentum of steady and rapid development, and significant progress
has been made in structural adjustment and energy conservation and emission reduction.

China's installed power generation capacity increased from 874 million kilowatts in 2009 to 1.
247 billion kilowatts in 2013, ranking first
in the world in terms of overall power scale.
The power supply structure has been continuously optimized, and the proportion of installed capacity of non-fossil energy power generation has increased significantly, from 25.
4% in 2009 to 30.
9%
in 2013.
The power grid's ability to optimize resource allocation, technical equipment and safety power supply has been comprehensively improved, and many indicators such as substation capacity and line length have leapt to the
first place in the world.

At the same time, the power industry continues to increase energy conservation and emission reduction, and thermal power units are developing
in the direction of large capacity, high parameters and environmental protection.
The national power supply coal consumption rate dropped from 340 g kWh in 2009 to 321 g kWh in 2013, the emission reduction capacity of air pollutants continued to increase, and the total emission continued to decline
.
Emissions of fine particulate matter, carbon dioxide and nitrogen oxides also continued to decline
.
The scientific and technological innovation ability of the power industry has been continuously improved, and the overall technical level has entered the world's advanced ranking
.
UHV transmission realizes "created in China" and "led by China"
.
China has completed the "two exchanges and four straight" UHV project
.
The first meeting of the new National Energy Commission emphasized the development of long-distance large-capacity transmission technology
.
UHV plays an increasingly important role
in ensuring energy security, controlling smog, improving energy efficiency, and serving economic and social development.

China has mastered advanced clean coal power generation technology, built the first integrated coal gasification combined cycle (IGCC) demonstration power station, put into operation a carbon dioxide capture demonstration project with an annual output of 120,000 tons, and a 600,000-kilowatt supercritical circulating fluidized bed unit
。 Master the manufacturing technology of the world's largest capacity 700,000 kilowatt hydropower unit; It is developing the world's largest passive pressurized water reactor nuclear power unit and third-generation nuclear power technology with independent intellectual property rights; The 5 MW wind turbine with completely independent intellectual property rights has been connected to the grid for full power generation, and the 6 MW offshore large-scale wind turbine has been successfully installed, marking that China's clean energy technologies such as hydropower, nuclear power and wind power have entered the world's advanced ranks
.

At the same time, the report shows that the current development of the society is facing a new situation and new tasks
.

First, there is still a lot
of room for energy and power development.
Energy supply and security have a bearing on the overall situation
of China's modernization drive.
With the acceleration of China's new industrialization and urbanization, the future energy and electricity demand will maintain rigid growth
.
It is estimated that in 2020 and 2030, China's installed power generation capacity will reach 2 billion and 2.
7 billion kilowatts respectively; The electricity consumption of the whole society reached 8.
4 trillion and 11.
5 trillion kWh respectively; Annual per capita electricity consumption is 5,800 and 7,400 kWh, respectively, 66% and 85%
of the current OECD average.
In order to meet the electricity demand of economic and social development, according to the planning of the State Grid Corporation, from 2014 to 2020, the power grid investment exceeded 3 trillion yuan, and in 2017 and 2020, "three vertical and three horizontal" and "five vertical and five horizontal" UHV AC and 13 and 27 UHV DC were built, and the cross-regional transmission capacity reached 290 million and 450 million kilowatts
respectively.
As the lifeblood of the national economy and important infrastructure, the power industry has broad room
for development.

Second, the trend of clean development is becoming increasingly prominent
.
In order to cope with the climate change and environmental pollution caused by the development and utilization of traditional fossil energy, the adjustment of the energy structure characterized by cleanliness has been accelerated, and clean energy has been vigorously developed and utilized, and the cleaning of conventional energy and the electrification of energy consumption have become the leading direction
of energy development.
At present, the constraints on energy resources and ecological environment are constantly tightening, especially the urgent need to control smog, which further highlights the importance and urgency of
clean development.
China is rich in clean energy resources, and hydropower can develop 600 million kilowatts; The developable resources of wind energy and solar energy are 2.
5 billion and 2.
7 billion kilowatts
respectively.
These clean energy resources are mainly distributed in the western and northern regions
.
According to the national plan, by 2020, China's installed wind power capacity will exceed 200 million kilowatts, photovoltaic power generation will exceed 50 million kilowatts, and hydropower will be installed about
350 million kilowatts.
This puts forward many new topics for the planning and development of power supply and power grid, and also provides a broad platform
for the society to play a role.

Third, improving the ability of continuous innovation faces a difficult task
.
Innovation is an inexhaustible driving force
for the prosperity of a country and nation.
The role of innovation in the power industry has been crucial
to the rapid development of the power industry in recent years.
The 18th National Congress of the Communist Party of China emphasized the implementation of the innovation-driven development strategy and placed innovation at the core of the overall development of
the country.
At present, the world's scientific and technological progress is changing with each passing day, a new round of energy reform is advancing in depth, the power industry is highly integrated with modern information technology, network technology and intelligent technology, a large number of new technologies, new equipment, new materials and new processes are widely used in the power system, and the scientific development of the power industry has higher and higher
requirements for innovation 。 At the same time, we have many problems to be overcome in the fields of new energy development, fourth-generation nuclear power, clean and efficient coal-fired power generation, large-scale power grid operation and management, and large-scale energy storage, and some core technologies and key equipment can not only be learned abroad, but also cannot be bought, and require the majority of scientific and technological workers to persevere in overcoming difficulties and play a leading and supporting role in technological innovation and
knowledge innovation.

Fourth, the transformation of government functions has put forward new requirements
for the development of the society.
With the transformation of the government's functions, simplification of administration and decentralization, some social functions will be entrusted to the scientific and technological community, which provides unprecedented opportunities for the development of the society and gives the society new responsibilities
.
This year, the Ministry of Civil Affairs abolished the administrative examination and approval of the establishment, change, and cancellation of registration of branches of national social organizations, and allowed "one industry and multiple associations", which will play a positive role in promoting the reform and development of the society and stimulating the vitality of the society, and at the same time put forward higher requirements
for the organizational and institutional construction of the society.
