Abstract

The invention discloses an auxiliary relay protection monitoring processing system and a processing method thereof. The auxiliary relay protection monitoring processing system comprises a data obtaining unit, a data processing unit, a data information extraction unit, a data monitoring device, a real-time data recording system, a relay protection monitoring server, a fault information analysis display unit, a control unit and a relay protection unit; an input end of the data processing unit is connected with a power grid dispatching center and an output end is connected with an input end of the relay protection unit respectively through the data processing unit, the data information extraction unit, the fault information analysis display unit and the control unit; an output end of the data detection device is connected with the fault information analysis unit sequentially through the real-time data recording system, the relay protection monitoring server and the fault information analysis display unit. The auxiliary relay protection monitoring processing system and the method can accurately position the fault reason and fault points, reduces the power failure time for overhaul, improves the utilization relate and the operation reliability of equipment and meanwhile reduces overhaul costs.

Description

technical field [0001] The invention relates to the technical field of power grids, in particular to a relay protection auxiliary monitoring and processing system and a processing method thereof. Background technique [0002] Relay protection is an integral part of the power system. It plays an extremely important role in ensuring the safety, stability and economic operation of the system, and preventing the expansion of faults and the occurrence of accidents. In order to meet the requirements of the four characteristics (reliability, selectivity, rapidity, and sensitivity) put forward by the power grid for relay protection, and to give full play to the effectiveness of relay protection devices, the protection settings must be reasonably selected to maintain each protection interrelationships between them. With the rapid development of the national economy and the scale of the power grid, the safe operation of the power grid has higher and higher requirements for the safety...
