A method for establishing online monitoring data model of large power grid substation equipment

Abstract

The invention relates to an on-line monitoring data modeling method of bulk grid transformer equipment. The method comprises the following steps of 1) modifying substation system models, 2) allowing all-level main monitoring stations to receive the substation system models and analyzing a substation code and coordinate information in each substation system model, 3) matching the single substation system model with corresponding substation information in a primary wiring diagram of a regional grid according to the substation code and the coordinate information, 4) linking the substation system models with corresponding substation points in the primary wiring diagram of the regional grid, forming a provincial-level model file and forming version numbers, 5) forming and sending new substation system model version numbers to the all-level main monitoring stations after the substation system models are modified, and achieving automatic update of a network-level model by Step 2)-Step 4), and 6) splicing provincial-level on-line monitoring system models into a network-level on-line monitoring system model. The method is easy to realize, can reduce the update time of the model, and can raise an application level of the on-line monitoring model.

Description

technical field [0001] The invention relates to a method for establishing an online monitoring data model of a large power grid substation equipment, in particular to an IEC61850-based method for modeling the online monitoring data of a large power grid substation equipment, belonging to the technical field of online monitoring data communication of the substation equipment. Background technique [0002] With the expansion of the power system, it is not only necessary to use the overall operation information of the power system, but also to monitor the status of a large number of power equipment. A large amount of information requires fast and accurate integration and transmission in various automation systems. How to integrate and manage this information has become a big problem. [0003] The IEC6850 standard has been highly valued at home and abroad, and a large number of researchers have conducted long-term research on it. The online monitoring data modeling in the subs...
