Electric power engineering, that is, the engineering related to the production, transmission and distribution of electric energy, in a broad sense, also includes the application of electricity as power and energy in a variety of fields. The transmission and distribution of electric energy is mainly realized through high-voltage and low-voltage AC power grids. In the past 30 years, HVDC transmission technology has advanced rapidly and has been more and more widely used in some transmission fields.
Therefore, as the direction of the development of transmission engineering technology, the focus is on the study of ultra-high voltage (more than 1 million volts) AC transmission and DC transmission technology to form a larger power network; At the same time, it is necessary to study the technical aspects of superconductor energy delivery.

The experience of countries around the world shows that the development rate of power production should be higher than the development rate of other sectors in order to promote the coordinated development of the national economy, so the power industry is also known as the "pioneer" of the national economy.
If China's economic development is compared to the "body", then the construction of electric power engineering is undoubtedly the "muscles and bones" that support the flexible movement of the body. The continuous advancement of power engineering construction is like providing unlimited energy for the muscles and bones, and abundant energy is a strong guarantee for the effective operation of various functions of the body.
In 2012, affected by the slow recovery of the world economy and domestic macroeconomic control, China's economic growth continued to decelerate, and the annual GDP was 519322 billion yuan, which was calculated according to the comparable **, an increase over the previous year. Since 2000, the rate of China's electricity consumption and production has been higher than the GDP growth rate, which makes the electricity (production and consumption) elasticity coefficient greater than 1 for a long time, so it has been difficult to reduce the energy consumption per unit of GDP, indicating that China's electricity consumption momentum is strong.
During the 12th Five-Year Plan period, the national investment in the power industry will reach one trillion yuan, an increase of 68% over the 11th Five-Year Plan. In terms of power engineering construction, the "Twelfth Five-Year Plan" power supply investment is about one trillion yuan, accounting for 52% of the total power investment. In 2015, the installed power generation capacity of the country will reach about 100 million kilowatts, with an average annual growth.
Among them, hydropower is 100 million kilowatts, pumped storage is 41 million kilowatts, coal power is 100 million kilowatts, nuclear power is 43 million kilowatts, natural gas power generation is 30 million kilowatts, wind power is 100 million kilowatts, solar power generation is 2 million kilowatts, biomass power generation and other 3 million kilowatts.
In terms of power grid construction, the "Twelfth Five-Year Plan" plans to invest about one trillion yuan in power grids, accounting for 48% of the total power investment. In 2015, the country will form a "three vertical and three horizontal" main grid with North China, East China and Central China UHV power grid as the core. The energy bases of Ximeng, Mengxi, Zhangbei and Northern Shaanxi transmit power to North China, East China and Central China through three longitudinal UHV AC channels, and North China Coal Power and Southwest Hydropower transmit power to North China, Central China and the Yangtze River Delta UHV ring network through three horizontal UHV AC channels.
The rapid development of electric power engineering and the rational construction structure have provided a strong guarantee for China's economic development, and the strong "muscles" have promoted the sound and rapid development of China's national economy.

In terms of school, North China Electric Power University is better, and at least five graduate directions in electrical engineering are ranked first. In order for the country to achieve a well-off society in an all-round way in 2020, electricity must go first, electricity is the foundation of the national economy, and electricity is a new and popular major before 2020. This is also illustrated by the employment rate of electricity in recent years.
