Embodiment Construction

[0039] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0040] 1. Automatic import of IEC61970 CIM scheduling model, E format measurement file and online monitoring IEC 61850 SCD file

[0041]The E-format measurement file 3 is updated every three minutes, and the CIM scheduling model and 61850SCD file are uploaded to the remote center when they are updated, which is an irregular update. The remote center needs to constantly monitor whether there are changes in these files, and if any changes are detected, the background program will automatically import and incrementally update.

[0042] 2. Unified modeling of CIM scheduling model, E format measurement file and IEC 61850SCD file, automatic splicing

[0043] Complete the association between the online monitoring IEC 61850 measuring point model and the CIM 61970 scheduling primary model to form a unified primary model and measurement model....

Abstract

The invention relates to a method for unifying models of on-line monitored first and secondary equipment of a power grid. The method comprises the following steps: utilizing an IEC61850 logic node LN to perform physical modeling on the on-line monitored secondary equipment: in the same device using a sensor to measure, LN embodiments are newly established for data of different measured objects; adding a uri (uniform resource identifier) attribute and a devid attribute to each LN; applying IEC68150 LN to modeling the on-line monitored secondary equipment; utilizing the LN to expand the attribute uri so as to realize the modeling related and unified with the first equipment; and utilizing the LN to expand the attribute devid so as to realize the grouping of measure points of the secondary equipment under the first equipment. According to the method, an IEC61970CIM scheduling model, an e-format measurement model and the secondary equipment (online monitoring device) are automatically introduced and spliced, so as to generate a complete once model and a measuring model. On the basis of the complete once model and the measuring model, the comprehensive information display, inquiry and historic curve display are carried out.

Description

technical field [0001] The invention relates to the integration and integration of the model and data between the IEC 61970 primary model and data of the electric power dispatching and the IEC 61850 secondary equipment of the online monitoring system in the electric equipment online monitoring system. Background technique [0002] The equipment monitoring system needs to access the models and data of different systems, and integrate and unify the models and data, so as to provide the following technical means for online monitoring, status evaluation, maintenance, defect management, etc. of power equipment: [0003] 1. Real-time and historical data collection, storage, analysis, monitoring, display, alarm, comprehensive query and other functions of equipment status information [0004] 2. Provide data basis for advanced application functions such as equipment status evaluation [0005] The real-time models and measurement data that need to be collected by the electric equipm...
