Embodiment Construction

[0025] Such as figure 1 The shown electric equipment remote monitoring and diagnosis center computer server is connected with each dispatching subsystem computer server through the network.

[0026] The invention uses the ODBC driver to acquire equipment and measurement models from the dispatching subsystem according to subscription / publishing content, associates them with the global model through automatic maintenance, and simultaneously takes real-time data of the corresponding system and stores them in the public cache area. For the system structure of the whole scheme, see Figure 4 . All dispatching subsystems write data into the dispatching subsystem data platform, and each dispatching subsystem obtains the required data of other dispatching subsystems from the dispatching subsystem data platform.

[0027] The whole scheme includes the establishment of the measurement model of the power equipment of the dispatching subsystem and the completion of the data interaction o...

Abstract

The invention discloses a method for data interaction and modeling of a dispatching subsystem, which performs the data interaction on the dispatching subsystem after building object mapping attributes and electric equipment measuring models of the dispatching subsystem, wherein the method comprises the following steps of: a) associating the multi-dimensional data of the dispatching subsystem with a global public object model, and building a mapping relationship of the public object attributes and the multi-dimensional object attributes of the multi-dimensional data of the dispatching subsystem in the global public object model; b) utilizing data interaction of the dispatching subsystem in a subscription / publish mode, and synchronizing the multi-dimensional data of the object attributes which form a mapping relationship with the dispatching subsystem to an abstract caching template in real time via a real-time caching model and an information mechanism; and c) performing generation of an XML (Extensive Makeup Language) description file of the multi-dimensional data model of the dispatching subsystem and the data interaction between the dispatching subsystems based on the driving of a cross-platform database via a subscription / publish mode driven by an event. The method for the data interaction and the modeling of the dispatching subsystem ensures the reuse of the abnormal-structure dispatching subsystem model in a manner of a mapping model, so that the data mode of the model is stable relatively.

Description

technical field [0001] The invention relates to a method for data interaction and modeling between a remote monitoring and diagnosis center and each scheduling subsystem, in particular to a data interaction method for scheduling subsystems based on a global mapping model by means of event service subscription / publishing. Background technique [0002] With the continuous expansion of the scale of the power grid, the workload of power grid monitoring and operation and maintenance is increasing day by day. Each major has established its own information dispatching subsystem, such as: lightning monitoring system, icing monitoring system, neutral point DC system, transformer Oil chromatography systems and more. Each dispatching subsystem is a necessary supplement to the power information system, providing professional data for production, evaluation, analysis, maintenance, etc. In the past, each dispatching subsystem was built independently, and each dispatching subsystem served...
