Abstract

The present invention provides a ring network-based in-situ protection device with a master mode data transmission method. The present invention realizes the transmission of management data through the gigabit ring network, improves the setting speed of the pressure plate and the fixed value, and utilizes the ring network Realize the monitoring of the running status of the protection sub-machine, adopt the mode of management host and protection sub-machine, realize the intercommunication of internal management data of the protection device, reduce the dependence of the protection device on the management unit, improve the reliability of protection, and use data transmission fault-tolerant technology at the same time Further strengthened the reliability of management data transmission.

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...
