Problems solved by technology
The communication and information exchange adopts the polling method, and some key points are actively reported, but the reporting process adopts the judgment of the bus status, and then sends the message, and sends it repeatedly after failure. If the number of failures exceeds the limit, an error will be reported.
[0004] From the perspective of networking mode, it relies too much on manual operation, which takes up a relatively large amount of manpower. From the perspective of information interaction, the current message interaction capability is in the number of messages, message flow, and message timeliness. There is a relatively large room for improvement in terms of sex and other aspects

The invention relates to the fields of distribution network automation and relay protection, and discloses an electric power automation terminal autonomous networking system based on time division multiple access. The electric power automation terminal autonomous networking system comprises terminals and a station end which perform information interaction through a time division multiple access way, wherein a plurality of terminals are provided; the terminals perform information interaction through the time division multiple access way; each terminal is based on a uniform synchronous clock source; and each terminal in the autonomous networking system adopts a unique coded ID. The autonomous networking system has great advantages in comparison to the manual equipment entry way of a current power distribution network; labor force can be saved; and manual errors can be reduced automatically. Moreover, the effective load of a whole network can be increased, and key information can be effectively processed in time.
Description
technical field [0001] The invention relates to the field of distribution network automation and relay protection, and more specifically, to an autonomous networking system for power automation terminals based on time division multiple access. Background technique [0002] With the advancement of the information age, informationized and intelligent power distribution terminals cover the entire smart grid, and a large number of smart power distribution terminals have been widely used in the smart grid. The most critical technologies are networking and communication. Networking can complete the information interaction and aggregation of each terminal, realize the sharing of information of each node by the master station, and accurately and timely transmit the commands of the control center to the distributed remote terminals. The distribution line is the line that directly supplies power to the end user, and the network composed of such lines is usually called the distribution...
