Electric power secondary system safety incident analysis method for non-conformity strategy access

Abstract

The invention provides an electric power secondary system safety incident analysis method for non-conformity strategy access. The method includes the steps: (1) extracting a characteristic value of a new alarm when a new alarm is given; polling a device linked list in a real-time non-conformity strategy access alarm list, judging whether the new alarm is positioned in a node of the device linked list or not, and turning to the step (2) if the new alarm is positioned in the node of the device linked list; turning to the step (3) if not; (2) indicating the new alarm if the new alarm is positioned in the node of the device linked list, and associating the new alarm with an alarm maintained by the node; (3) finding a corresponding position in the device linked list and inserting the new alarm if not; (4) updating the real-time non-conformity strategy access alarm list. By the aid of association mining, numerous non-conformity strategy access alarm messages appearing on the site is analyzed twice to form a more significant alarm message, and function support is provided for rapid positioning and timely processing of the alarm.

Description

technical field [0001] The invention relates to an alarm event analysis method, in particular to a power secondary system safety event analysis method for non-compliance policy access, and belongs to the technical field of power system dispatching. Background technique [0002] The internal network security monitoring platform of the power secondary system (referred to as the internal network security monitoring platform) is mainly used for security event monitoring, security event analysis, statistical reports, asset management, etc. of the internal network of the power secondary system, and is to maintain the security and stability of the power secondary system Important technical support for operation. [0003] In the Chinese invention patent application with publication number CN101222725A, a method for reducing the number of northbound interface alarms by using alarm merging is disclosed. Among them, the network element management system EMS reports alarms or alarm rec...

Problems solved by technology

However, there are also some problems: the intranet security monitoring platform mainly implements the function of summarizing alarm information, and does not perform secondary analysis on massive alarm data, resulting in numerous on-site alarms and weak information correlation, which is not conducive to reflecting the security of the secondary power system Risk indicators, on the contrary, cause on-site users to be exhausted in solving various alarms, which seriously affects the vitality of the intranet security monitoring platform; the analysis and storage of intranet security monitoring data and the compression and merging of alarms are performed asynchronously. The pressure is high, and the alarm generation cycle is also long
