Problems solved by technology

Now most of the manufacturers’ data models, data interfaces, and underlying frameworks are not unified. The memory is used separately from the data collection end to the data provided to the station end, which consumes a lot of system resources, slow updating and accessing data, and data inconsistency. the inconvenience

Abstract

The invention relates to an IEC61850-based communication component and application component data interface method. The method comprises the steps of initializing resolution configuration files; putting data into a shared memory according to classified formats, and associating and mapping the data to corresponding regions of a real-time database through addresses; and connecting an external application device, connecting a system according to each protocol, assigning a value to a real-time database interface according to a format of an interface protocol, an IEC61850 server communicating with a client, mapping and associating the data to the shared memory according to different services, a real-time database interface application program transmitting different messages according to different functional data, converting into protection measurement and control protocol formats, transmitting to the external application device, and achieving the function of information interaction with a substation secondary device. The invention can complete interface processing between IEC61850 data and the database and various advanced application data pools directly, can cope with the development needs of large power grids and intelligent stations, and has an important practical significance for the access of existing equipment.

Description

technical field [0001] The invention relates to a communication interface realization method of power system automation equipment / products, in particular to a data interface method and system based on IEC61850 communication components and application components. Background technique [0002] The IEC61850 standard is uniformly used for communication in smart substations, which is the basis of relevant standards for smart substations. The standard establishes an abstract model on the application layer through the abstract application service interface (AbstractCommunicationServiceInterface, referred to as ACSI), describes the data exchange between each interface, adopts an object-oriented modeling method, and is based on IEC61850 model data and multiple links of traditional equipment real-time data interface Must focus on the processing of mapping or conversion between different models. In the past, substation automation devices organized data for functions. There was a clear...
