Abstract
The invention discloses an electric power system telecontrol data quality management method and system based on a feature matching knowledge base, and the method comprises the following steps: S1, obtaining telecontrol data of an electric power dispatching automation system, employing a split item algorithm to disassemble the telecontrol data, and extracting a feature quantity needing to be matched; S2, calling a feature matching knowledge base, identifying a matching relationship between the feature quantity and the feature factor, and judging the normalization of the telecontrol data; S3, calling a feature matching knowledge base, identifying the feature factor matching condition of the reference telecontrol data, and judging the integrity of the telecontrol data; and S4, judging a telecontrol data management direction according to the standardization and integrity of the telecontrol data, thereby realizing quality management of the telecontrol data. Full-automatic auditing of telecontrol data quality of the power dispatching automation system is achieved, manual recognition is not needed, automatic operation, maintenance, quality improvement and efficiency improvement are achieved, meanwhile, an evaluation result is accurate, and the operation efficiency is high.
Description
technical field [0001] The invention relates to the technical field of power grid automation, and more specifically, to a method and system for controlling the quality of electric power system telecontrol data based on a feature matching knowledge base. Background technique [0002] With the rapid increase in the scale of the power grid, the data of substations connected to the master station of electric power dispatching automation through telecontrol has shown a massive growth. In order to ensure the work quality of the centralized dispatching and monitoring of power grid operation, further prevent the risks of power system leakage monitoring and false alarms, and eliminate the hidden dangers of equipment monitoring and alarm setting errors and omissions, higher requirements are put forward for the integrity, standardization, and accuracy of telecontrol data . [0003] At present, when new substations and devices are connected to the power dispatching automation system, t...
