A multi-source data checking method for electric power dispatching automation system

Abstract

The invention discloses a multi-source data verification method for a power dispatching automation system. The method is characterized by comprising the following steps: S01, setting a unique symbolic ID of each measuring point in the power dispatching automation system, and setting the parameter and information table of each channel, wherein the data ID of acquired data at an identical measuring point of different channels is the ID of the measuring point; S02, comparing the differences among different acquisition channels and state estimated values of the data at the identical measuring point in real time on the basis of the data IDs in the system, wherein data of a fault source is not considered in comparison; and S03, recording the difference values of each measuring point ID among different data sources, adding the inconsistent count of data on the measuring point with 1 when the difference values satisfy a set condition, and transmitting alarm information in case of inconsistent multi-source data of a current measuring point ID when the count satisfies a set condition. The possible risk of data error caused by a large amount of multi-source data switching is solved effectively, and the data verification efficiency of the system is increased.

Description

technical field [0001] The invention relates to a multi-source data checking method of an electric power dispatching automation system, which is used for real-time checking of the correctness of all collected data in the electric power dispatching automation system, and timely alarming of erroneous data, belonging to the technical field of electric power dispatching automation. Background technique [0002] Multi-source data has two meanings: one is the data obtained by different data communication methods (conventional RTU, network RTU, substation integrated automation, and communication with external systems) for the same measuring point of a certain plant, and the other is the status Data generated by software or manual operations such as estimation and operator input. Therefore, a measurement point in the real-time database often has multiple data sources, that is, multiple data sources. [0003] The traditional data multi-source processing method of power dispatching a...

AI Technical Summary

Problems solved by technology

When the system is running normally, the current source data participates in various calculations and is monitored by the dispatcher, so its correctness can be quickly judged. However, the data of other sources is not monitored in real time, and it may be discovered after the data source is switched. The phenomenon of incorrect data affects the normal operation of the power dispatching automation system
