Abstract

The invention relates to a grid fault recording data acquisition method and a grid fault recoding data acquisition system. The method comprises the following steps: when a power grid has a fault, a fault recorder networking system uploads corresponding fault recording data to a data server in a power system safety zone III; an IDC firewall synchronizes the fault recording data in the data server to an outer-net application server preset in a DMZ zone; a data issuing server is also set in the DMZ zone, and the data issuing server is in communication connection with the outer-net application server; the data issuing server receives an access request of acquiring the fault recording data sent by mobile equipment subjected to encryption by a boundary firewall, acquires corresponding fault recording data from the outer-net application server according to the access request, and returns the fault recording data to the mobile equipment. The method and the system disclosed by the invention can bring convenience for workers to acquire the grid fault recording data in real time, thus being favorable for timely providing professional support for fault analysis.

Description

technical field [0001] The invention relates to the technical field of electric power systems, in particular to a method and a system for acquiring wave recording data of power grid faults. Background technique [0002] According to the characteristics of the power secondary system, it is divided into a production control area and a management information area. The production control area is divided into a controlled area (safety area β… ) and a non-controlled area (safety area β…‘). The information management area is divided into production management area (safety area III) and management information area (safety area IV). Different security zones determine different safety protection requirements, among which the security level of security zone I is the highest, followed by security zone II, and the rest are deduced by analogy. The current power grid fault analysis system is mainly deployed in safety area II and safety area III, and the data in safety area II and safety area...
