Embodiment Construction
[0049] The present invention will be further described below with reference to the accompanying drawings and in conjunction with specific embodiments.
[0050] figure 1 It is a system structure diagram of a specific embodiment of the present invention, in which two signal input methods are given: merging unit + GOOSE network, or traditional PT / CT transmission signal + switch hard node.
[0051] In this specific embodiment, the IEC 61850 model is uniformly established on the server side in accordance with the requirements of the IEC 61850 standard, and a fault recording logic module and a transmission line parameter synchronous measurement logic module with the same hardware platform are provided. The fault recording logic module performs start-up judgment according to the calculation results If there is a startup, a fault file will be generated to record transient faults and dynamic data, and to complete the offline analysis of the recorded wave data; the logic module for sync...
