Abstract

The present invention provide a modeling method for intelligent substation secondary equipment interval information model. The method particularly comprises the following steps of: establishing an association relationship between a primary equipment model and a secondary equipment model, dividing a secondary equipment interval model, and automatically collecting secondary equipment elements to the secondary equipment interval model. According to the method, the association relationship between the primary equipment model and the secondary equipment model is established, and advanced applications of intelligent analysis of mutual interference of reorganization and expansion, intelligent alarming, five-prevention interlocking, data identification and the like are powerfully supported, thereby reducing labor and time consumption, improving the security and stability of a substation and a power grid, and enhancing the support of the substation to a primary station; According to the method provided by the present invention, the association relationship between the primary equipment model and the secondary equipment model in an SCD (substation configuration description) model of the intelligent substation can be accurately analyzed, so that isolated states of information models can be avoided and correct functional analysis application of intelligent alarming, five-prevention interlocking, data identification and source-end maintenance in the intelligent substation can be facilitated.

Description

technical field [0001] The invention relates to a modeling method, in particular to a modeling method for an intelligent substation secondary equipment interval information model. Background technique [0002] In 2009, the State Grid Corporation of China began to carry out the pilot construction of smart substations. In order to further standardize and refine the IEC61850 modeling rules and configuration process, the State Grid Corporation of China organized research on the principles and processes of engineering model modeling, and formulated relevant standards and specifications. An important task in the configuration work of the intelligent substation system is to instantiate the IED according to the ICD (IED capability description) file provided by the equipment manufacturer, configure the relevant communication parameters and connect the virtual terminals to form a substation configuration description (SCD) file for the whole station. [0003] The secondary equipment mo...
