Embodiment Construction

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0043] Such as figure 1 As shown, the intelligent matching method of electric power multi-monitoring point fault characteristic value of the present invention is based on technologies such as SCADA system and big data application. An alarm will be generated. Create a feature package, select the corresponding alarm information, lock the monitoring point information, and associate the knowledge base.

[0044] When the subsequent SCADA data is transmitted, ...

Abstract

The invention relates to an intelligent matching method and device for fault characteristic values of multiple power monitoring points, and the method comprises the following steps: 1), a power fault characteristic value storage process: building a characteristic packet through historical data, selecting corresponding alarm information, locking monitoring point information, and associating a knowledge base; and 2) a power failure characteristic value matching process: comparing real-time data with data in a characteristic packet, and when remote signaling and telemetering data respectively meet matching rules, giving an alarm. Compared with the prior art, the method has the advantages of solving the problem that a fault cannot be accurately positioned through single alarm and the like.

Description

technical field [0001] The invention relates to the technical field of power system fault maintenance, in particular to a method and device for intelligently matching fault characteristic values ​​of electric power multi-monitoring points. Background technique [0002] SCADA (Supervisory Control And Data Acquisition) system, that is, data acquisition and monitoring control system. The SCADA system is a computer-based DCS and power automation monitoring system; it has a wide range of applications, and can be used in many fields such as data acquisition, monitoring control and process control in electric power, metallurgy, petroleum, chemical industry, gas, railway and other fields. [0003] At present, after the power company system generates a work order, the maintenance personnel manually select the knowledge base according to the fault phenomenon, but there are a large number of knowledge bases for the same or similar fault phenomena, and the maintenance personnel have no ...
