Problems solved by technology

However, if the device-level modeling method is continued in the function of the relay protection system, the granularity will be too inconsistent. Moreover, the same function instance cannot be replicated and reused because it belongs to different devices. Taking advantage of standardization, on the cont

Embodiment Construction

[0037] The present invention will be further described below.

[0038] Starting from practical application requirements, the present invention introduces the specification description language (Specification Description Language, SDL) into the professional field of relay protection for the first time. From the point of view of system function, it is considered to model it, with the help of state machine, graphical description and virtual realization.

[0039] The present invention is realized by taking the following steps:

[0040] (1) The relay protection system model based on the IEC 61850 standard is mapped to the model based on the IEC 61499 standard according to the mapping principle, and the relay protection function state transition state machine model is obtained. The mapping correspondence is shown in Table 1:

Abstract

The invention discloses a relay protection system functional modeling method based on an IEC61850 standard. The method comprises the following steps of mapping a model based on the IEC61850 standard to a model based on an IEC61499 standard according to a mapping rule to obtain a functional state transition state machine model; performing graphical description on a state machine through an SDL (system descriptive language); compiling a correct system description under a modeling environment through a Cadvanced-to-C tool to generate a standard C code program and an interface function which are consistent with an SDL graphical description system; implementing the interface function; completing the integrating and compiling of the program and a Win32 platform to obtain a practical virtual realizing system consistent with a function of an object system. According to the method disclosed by the invention, the problem that no relay protection system-level modeling method is provided is solved; the efficiency of an application scene such as system test can be improved, and the relevant workload caused by a functional change is reduced.

Description

technical field [0001] The invention belongs to the field of electric power engineering, and in particular relates to a method for modeling the function of a relay protection system based on the IEC 61850 standard. Background technique [0002] With the rapid development of smart grid construction, the realization of relay protection functions is basically based on the IEC61850 international standard for information modeling and function modeling. Through the flexible configuration of ICD, CID, SCD and other model files and intermediate node files, with the help of An efficient and reliable communication network realizes functions that cannot be realized by conventional relay protection, and also makes relay protection change from a general device to a relay protection system, which reflects the application of new technologies in space and time. And to a certain extent, higher requirements are put forward for the functional modeling of the relay protection system level. [...
