[0002] Power engineering refers to engineering related to the production, transmission and distribution of electric energy. In a broad sense, it also includes engineering that uses electricity as power and energy in various fields. At the same time, it can be understood that power transmission and transformation industry expansion projects, power shortages will seriously hinder the development of the national economy. The experience of countries around the world shows that the development speed of electricity production should be higher than the development speed of other sectors in order to promote the coordinated development of the national economy.
