Use of industrial switches in smart grid power systems
The on-line monitoring of power system is an indispensable part in the development of smart grid. Smart grid not only means intelligent control, but also includes intelligent information processing and control of power grid operation. Intelligent control can be realized only when information intelligent management is achieved. Here's a look at the uses of industrial switches in smart grid power systems.
1.Use of industrial switches in smart grid power systems
1. in recent decades, the progress of science and technology, intelligent application system, intelligent urban transportation, intelligent home system; The development of electric power network is the same, "electric power network 2.0" -- smart grid, has been the future direction of electric power network construction.
2. In the process of building smart grid, the development trend of online monitoring technology of power equipment is fast. Most of the transformer equipment and generator sets, cables, routes and so on have online monitoring projects.
3. industrial Ethernet switch as a particularly important distribution network communication solution, the following from the protocol, networking mode of the corresponding analysis.
4. The protocol standardization of industrial switches has long been carried out, including the underlying protocol, redundancy technology protocol, management protocol, network precise clock transmission protocol, etc. The products of different manufacturers have good interoperability and can realize the hybrid networking scheme. The working range of -40℃ -- 85℃ can fully meet the industrial requirements and meet the construction of distribution network system.
5. Industrial Ethernet switches usually adopt piecewise redundancy, intersecting ring, tangential ring and other forms to improve the stability of the networking scheme. A variety of photoelectric ports are flexibly configured, highly integrated, and the elastic design is more convenient to provide help for power grid construction.
6. Intelligent digital signal communication is realized in smart power grid. The current and voltage signals collected by electronic transformers are converted into digital signals at various places and transmitted to switches through optical fibers.
7. Industrial switch plays a huge role in data collection, production management, operation and maintenance, security monitoring, measurement and user interaction. Industrial Ethernet technology, optical fiber technology, information processing technology and other development and penetration into various fields, power system monitoring technology is widely used in these advanced scientific research results, so that online measurement technology gradually toward the practical stage.
8. The application of industrial Ethernet switch in the construction of power network can comprehensively improve the depth and breadth of information perception in all aspects of smart grid, and provide high availability support for realizing the intellectualization of power system and the integration of information flow, business flow and power flow.
The above is about the "industrial switch in smart grid power system use" all content, hope to help you.
