Hello, Welcome to Double Circle Electronics Group Co., Ltd. official website!

Power system is a power production and consumption system composed of power plants, transmission lines, power supply and distribution stations and electricity consumption. Its function is to convert the primary energy of nature into electric energy by generating power plant, and then supply electric energy to all users through transmission,transformation and distribution. In order to realize this function, the power system also has corresponding information and control system in each link and different levels. It measures, adjusts, controls, protects, communicates and dispatches the production process of power, so as to ensure the users to obtain safe and high-quality power.

The main structure of power system includes power supply (hydropower station, thermal power plant, nuclear power plant, etc.), substation (boost substation, load center substation, etc.), transmission, distribution lines and load center. The power supply points are also interconnected to achieve energy exchange and regulation between different regions, thereby improving the security and economy of power supply. The network composed of transmission lines and substations is usually called power network. The information and control system of power system consists of various testing equipment, communication equipment, safety protection device, automatic control device, monitoring automation and dispatching automation system. The structure of power system should ensure the reasonable coordination of power production and consumption on the basis of advanced technology and equipment and high economic benefits.
