Embodiment Construction

[0014] The present invention will be further described in detail below through the specific examples, the following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention with this.

[0015] An online monitoring and communication method from a substation to a master station, the steps of the method are:

[0016] (1) After the IEC61850 server-side program of the substation obtains the online monitoring data of the sub-station, it is uniformly configured by the ICD file to form the online monitoring information model of the whole station. The online monitoring data of this embodiment can use the transformer oil chromatographic data. The information model has data attributes and data service functions. The online monitoring information model is mapped into a real-time data model library according to a certain structure in the memory, and is loaded by the communication driver to provide IEC61850 writing report control block se...

Abstract

The invention relates to an online monitoring communication method from a substation sub station to a main station. The method comprises the steps that after ICD file unified configuration, a whole station online monitoring information model is formed and is mapped into a real-time data model library; after communication driver loading, an IEC61850 report writing control block service is provided; the function of online monitoring data reporting of a substation sub station is completed; an IEC61850 main station program of the main station acquires online monitoring data by periodically calling a report reading control block service function; the data are parsed by a parse service of an online monitoring equipment model and are stored into the real-time model library according to a certain structure; and a memory data management program provides a data interface for an SCADA monitoring system, so that the online monitoring data are displayed in real time in the SCADA system. The method uses the latest IEC61850 specification of the international standard, has the characteristic of interconnection, and greatly improves the flexibility, the scalability and the maintainability of the online monitoring system.

Description

technical field [0001] The invention belongs to the field of intelligent substations, in particular to an online monitoring communication method from a substation to a main station. Background technique [0002] In the field of traditional substation on-line monitoring, the data access scheme between the substation and the main station mostly adopts a shared database or a communication protocol customized by the manufacturer. The mode of shared database has poor interactivity, and the master station does not have the function of controlling the equipment of sub-stations; the communication protocol of each manufacturer's self-defined mode program is quite different, and its maintainability is poor. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide an online monitoring and communication method from the substation to the main station. The flexibility, scalability and maintainability of the mon...
