specific Embodiment approach

[0022] The present invention relates to a specific implementation of an intelligent substation IED exchange method based on a resource object matching mechanism, including the following steps:

[0023] The first step is the definition and analysis of IED resource objects.

[0024] The analysis and decomposition of IED functions is to abstract and decompose the functions of smart devices into the smallest functional unit in IEC61850—the logical node—according to the functional needs of specific devices, combined with the logical node class defined by IEC61850 that represents a series of functions. Decomposing the internal functions of intelligent electronic devices into logical nodes representing these functions can realize the free distribution and allocation of functions, and change the communication between traditional devices into communication between logical nodes, which better meets the needs of communication .

[0025] The second step is the association of resource obj...

Abstract

The invention discloses an intelligent transformer station IED interchange method based on a resource object matching mechanism. The method includes the following steps: analyzing IED resource objects, associating the resource objects, associating IED with a transformer station model, associating ED with the IED, and launching a resource object matching mechanism. The advantages are that the influence of faults upon a system is avoided, the normal operation of the system is maintained, a self-recovery capability is exhibited, the fault-tolerant ability of an intelligent transformer station IED system is enhanced, the system reliability is improved, and the method has engineering application values.

Description

technical field [0001] The invention belongs to the technical field of intelligent substations, relates to the control and management of various intelligent electronic devices (IEDs) in the substation, is applicable to the configuration of IED data models in intelligent substations, and is an interactive IED in intelligent substations based on a resource object matching mechanism. sex method. Background technique [0002] The international standard IEC61850 for intelligent substation automation communication system proposes the communication service system of the data model and the construction method of the data model. In practical applications, IEDs produced by different manufacturers have differences in hardware and software implementations, and have different characteristics. Realizing the interchangeability between intelligent devices (IEDs) in substations is the focus of attention in the field of smart substations. [0003] The interchangeability of IEDs refers to the...
