Abstract

The invention provides a looped network-based data transmission method with a main mode for a localized protection device. According to the invention, the transmission of management data is realized through the gigabit ring network; the setting speed of a pressing plate and a fixed value is improved; meanwhile, the ring network is used for monitoring the operation state of the protection sub-machine, the mode of the management host and the protection sub-machine is adopted, internal management data intercommunication of the protection device is achieved, the dependence of the protection deviceon a management unit is reduced, the protection reliability is improved, and meanwhile the reliability of management data transmission is further enhanced through the data transmission fault-toleranttechnology.

Description

technical field [0001] The invention relates to the technical field of in-situ protection, in particular to a ring network-based in-situ protection device with a master mode data transmission method. Background technique [0002] Compared with traditional relay protection technology, in-situ protection technology has many advantages. The advantages of miniaturized protection device, higher protection level, stronger reliability, faster movement and more convenient operation and maintenance make in-situ protection Technology has been developed and applied rapidly. [0003] At present, the local busbar protection mostly adopts the scheme of distributed protection sub-machine function without master, and each sub-machine has complete protection logic and is responsible for the corresponding interval phase-separated tripping function. The entire set of busbar protection devices is connected to the intelligent management unit through the MMS dedicated network, and the intelligen...
