Embodiment Construction

[0014] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0015] This embodiment adopts PC-GOOSER software to the detection method of GOOSE message in a certain interval of digital substation, GOOSER software is developed by Sweden Megger company, and its specific steps are as follows:

[0016] (1) Use the computer to import the configuration language SCD file of the digital substation, which is configured by the system integrator, and display the description of the GOOSE information in the SCD file on the interface of this PC-GOOSER software, such as figure 1 Shown in the first 5 languages.

[0017] (2) Collect the GOOSE heartbeat messages sent by the IED device and display them one by one on the software interface. The collection method can directly connect the optical fiber to the IED device, or collect through a network switch. What this embodiment collects is the GOOSE heartbeat messag...

Abstract

The invention discloses a method for detecting GOOSE (generic object oriented substation event) messages of a digital substation, comprising the following steps of: firstly, introducing a system integrator-configured SCD (security coding device) file by a computer procedure, and displaying the GOOSE message contents of IED (intelligent electronic device), which are configured in the SCD file, on a software interface one by one; acquiring GOOSE heartbeat messages of the IED equipment, and displaying the heartbeat messages on the software interface one by one; and automatically comparing the GOOSE information in the SCD file with the acquired GOOSE messages, judging whether the GOOSE information in the SCD file and the acquired GOOSE messages are same or not, and analyzing. The method for automatically detecting the GOOSE messages is provided by using computer language, the introduced SCD file is compared with the captured GOOSE messages, the method can save a large quantity of manpower resources as compared with the prior art, the debugging efficiency of the digital substation can be improved, and the potential safety hazard can be reduced.

Description

technical field [0001] The invention relates to a method for detecting GOOSE messages in a digital substation, which is suitable for the technical fields of detecting the action characteristics of relay protection equipment in the digital substation and managing the version of configuration files of intelligent electronic equipment. Background technique [0002] With the rapid development of computer technology and the mature application of power system integrated automation technology, the application of IEC61850 series standards in substations can be realized. After the unified standard is applied to the whole station system, in theory, seamless connection between secondary devices of different manufacturers and different functions can be realized, and resource waste and interoperability problems caused by protocol conversion between different systems can be avoided. At the same time, the digital substation replaces the traditional copper cable with optical fiber, which ef...
