Electric power SCADA intelligent multi-dimensional query and maintenance method

Abstract

The invention relates to an electric power SCADA intelligent multi-dimensional query and maintenance method. The method comprises the following steps: SCADA data of the power equipment can be continuously transmitted; when the platform detects that the data exceeds a threshold value, an event list is generated, fault information is analyzed, information matching with a knowledge base is carried out, an optimal operation scheme is selected, processing steps, instruments, meters, safety tools, required materials and the like are automatically set, and the matching mode can be based on differentdimensions and different weights at the same time. Word segmentation processing is performed on the event description, the event description is compared with a white list and a black list of an electric power standard language library after word segmentation, and then querying is performed in a knowledge base; and after receiving the information, the maintainer maintains the faulty power equipment. According to the invention, the fault information and the corresponding solution are put into the knowledge base, the problem of difficulty in maintenance work is solved by using an intelligent maintenance strategy, and the work task of maintenance personnel is replaced to a certain extent, so that the problem that the fault maintenance of a large-scale information system is completed only by manpower and experience in the past is solved.

Description

technical field [0001] The invention relates to the technical field of power system fault maintenance, in particular to an electric power SCADA intelligent multi-dimensional query and maintenance method. 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] In the power system, the SCADA system is the most widely used and the technology development is the most mature. It occupies an important position in the telecontrol system and can monitor and control the operating equipment on site to realize various functions such as data collection, equipment control, measurement, parame...

Problems solved by technology

[0004] At present, after the power company system generates a work order, the maintenance personnel manually select the knowledge base, but there are so many knowledge bases that the maintenance personnel have no way to start, and do not know which one to use? Often do not select the knowledge base or select the wrong knowledge base, it is difficult to complete the maintenance task, which affects the company's work efficiency
