1. Electrical Engineering (Electrical power engineering) refers to the engineering disciplines related to the generation, transmission, and distribution of electrical energy; in a broader sense, it also encompasses the application of electricity as a source of power and energy across various sectors.

　　2. Since the 20th century, electricity generation has primarily relied on thermal power plants, hydropower stations, and nuclear power plants. In areas where conditions permit, tidal, geothermal, and wind power are also utilized. The transmission and distribution of electricity are mainly carried out via high- and low-voltage AC power grids. As the future direction of transmission engineering, research is focused on ultra-high-voltage (above one million volts) AC and DC transmission technologies to build even larger power grids. Technical challenges related to superconducting power transmission also require further study.

　　The large-scale power systems that emerged in the 20th century integrated power generation, transmission, transformation, distribution, and consumption into an organic whole, forming a physical engineering system within the social sector of material production that is characterized by a broader spatial scope, more stringent temporal coordination, and a highly complex hierarchical division of labor.

　　3. As a form of energy, electric power boasts numerous advantages, including ease of conversion and transmission, convenient control, user-friendliness, cleanliness, and cost-effectiveness. Since the 1880s, electric power has gradually replaced the steam engine—once the technological cornerstone of the 18th-century Industrial Revolution—and has become the technological foundation of both the material and cultural achievements of modern society. The transmission and distribution of electric power are primarily carried out via high- and low-voltage AC power grids.

　　Over the past three decades, high-voltage direct-current transmission technology has advanced rapidly and has been increasingly applied in various power transmission applications. Consequently, as a key direction for the development of power transmission engineering, research is primarily focused on ultra-high-voltage (above one million volts) alternating-current and direct-current transmission technologies to build larger-scale power grids. In addition, the technical challenges associated with superconducting power transmission also warrant further investigation.

　　4. Power Grid Development: During the 12th Five-Year Plan period, grid investment is projected at approximately RMB 2.55 trillion, accounting for 48% of total power-sector investment. By 2015, a national “three vertical and three horizontal” backbone grid will be established, with the North China, East China, and Central China high-voltage grids serving as its core. The Shimen–Mengzi, Mengshi–Zhangbei, and Beishan energy bases will supply power to North China, East China, and Central China via three vertical high-voltage AC transmission corridors, while coal resources in northern China and hydropower from the southwest will feed into the high-voltage interconnection network serving North China, Central China, and the Yangtze River Delta through three horizontal high-voltage AC transmission corridors.

　　5. The rapid development of power engineering and the rational structuring of its construction have provided strong support for China’s economic development, with a robust “root system” fostering the sound and rapid growth of the national economy.

　　The development of power engineering and automation also faces challenges; the following section primarily outlines these issues.

　　A shortage of highly specialized electrical engineering talent: In many Chinese universities, power engineering and automation are classified as science disciplines, yet relatively few institutions offer these programs, resulting in a small pool of students pursuing such majors. Even where these programs are available, much of the knowledge remains confined to theoretical instruction, lacking substantive practical application. Consequently, graduates often lack hands-on experience in the operation and maintenance of everyday facilities and equipment upon entering the workforce. This dearth of highly skilled professionals not only significantly hinders the advancement of electrical engineering but also, to some extent, affects the reliable operation and effective maintenance of automated electrical systems.
