Power system

Power system is a power production and consumption system, which is composed of power plant, transmission line, power supply and distribution and electricity consumption. Its function is to convert one natural energy into electricity through a power generation device, and then supply electricity, electricity, and distribution to all users. In order to achieve this function, the power system has corresponding information and control system in every link and different levels. It can measure, regulate, control, protect, communicate and schedule the power production process, so as to ensure users get safe and high quality power.

The main structure of the power system is power supply (hydropower station, thermal power plant, nuclear power plant and other power plants), substations (booster substation, load center substation, etc.), transmission, distribution lines and load centers. The power supply points are connected to each other to realize the electrical energy exchange and adjustment between different regions, thus improving the security and economy of the power supply. The network of transmission lines and substations is usually called the power network.

Building electric

With the development of economy, city construction change rapidly, modern office building internal professional facilities, high degree of automation, in order to ensure the overall operation of the advanced modern building electrical reliability, safety and intelligent equipment, electrical engineering in the strong and weak system installation method and installation quality is very important.

Industrial control system

With the further application and perfection of the enterprise information network, the real time monitoring of the field control information into the information network is an inevitable trend. In order to improve the social and economic benefits of enterprises, many enterprises in the management information system to establish a full range of information, it must be real-time data including the production site, to ensure real-time grasp the operating status of the production process, the scientific enterprise management decision-making, optimize the status of production, operation and management. One body of information control will create favorable conditions for the realization of enterprise integrated automation CIPA (computerintegratedplantautomation) and enterprise information.

The similarity between enterprise information network and control system in the process of system development is not accidental. In the development of computer control system, the emergence of control system with each structure always lags behind the development of corresponding computer technology. In fact, in most cases, it is after the emergence of a new technology in the field of computer that people begin to study how to apply this new technology to the field of control. Due to the differences between the two application environments, the technical details of the two environments have been modified and supplemented appropriately, but there are many common points in the principle and implementation of the key technologies. It is precisely because of the relationship between them in the process of development that it is possible to realize the integration of information and control.
