Abstract

The reliability of data transmission in traditional protection systems mainly depends on the redundant realization of the communication network. The protection devices in the system do not have the capability and transmission mechanism for redundant data transmission. In order to solve this problem, this paper proposes a data redundancy transmission method based on protection devices, so that the protection devices in the system can be directly connected to each other and data transmission can be realized. Through the repeated transmission and reception of data by different communication ports of each protection device, a set of multi-port data dynamic transmission strategy based on protection device is established, forming a redundant transmission method that does not depend on network communication equipment. This method reduces equipment costs while improving communication efficiency and reliability.
