Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0022] Such as figure 1 Shown is a method flow diagram of a preferred embodiment of the present invention. The present invention proposes a method for discriminating the validity of interval five defense data applicable to substations, comprising the following steps: 1) reading the five defense logic expressions; 2) extracting each logical variable in the five defense logic expressions; 3) discriminating The logic variable corresponds to the data quality bit Quality; 4) According to the quality value of the logic variable, the validity of the logic variable data is judged one by one; 5) If one of the five defense logic variables is invalid, the entire five defense logic data is invalid, and the...

Abstract

The invention discloses a method for discriminating the validity of interval five defense data applicable to substations, comprising the following steps: step SS1: reading the five defense logic expressions; step SS2: extracting each logic in the five defense logic expressions variable; step SS3: determine the corresponding data quality of the logical variable is Quality; step SS4: judge the validity of logical variable data one by one according to the value of the data quality bit Quality of the logical variable. The present invention can accurately, comprehensively and reliably judge the validity of the interval five-defense data by analyzing and processing the interval five-defense data of the substation control layer, making the judgment of the five-defense expression more reasonable, avoiding misoperation, and providing on-site operation and maintenance personnel with security.

Description

technical field [0001] The invention relates to a method for judging the validity of interval five-prevention data applicable to substations, and belongs to the technical field of substations. Background technique [0002] Preventing safety accidents is an important task for power grid safety production. In practice, multi-layer preventive measures are adopted to prevent accidents, and five preventions at intervals are one of them. The digital signal transmitted through the station control layer is used as a logical variable to form a five-defense logic expression to realize the five-defense logic operation, and associated with remote control operation, the interval five-defense function can be realized to ensure the safety of the operation and maintenance personnel during the operation of the substation. As an important function of the substation integrated automation system, the interval five defenses have been continuously improved and developed. Nowadays, with the conti...
