Basic knowledge of power systems

Release time：

2024-04-16

The power system is an integral part of modern life, its basic function is to convert energy into electricity and distribute it to users. The power system includes four parts: generation, transmission, transformation and distribution. The frequency characteristics of the power system depend on the frequency characteristics of the load and the frequency characteristics of the generator, while the voltage characteristics depend on the balance of active and reactive power supply and demand in each region. The short circuit of the power system may cause the rotor of the generator to accelerate, destroy the stability of the system, and even cause a large area of power failure. The transmission line is the main artery of the power industry, which is used to transmit electric energy and contact the power plants and substations to make them run side by side, realize the networking of the power system, and can realize the power transmission between the power systems.
