Embodiment 1

[0039] The GOOSE overall test device of the smart substation of this embodiment is as figure 1 As shown, it includes a control unit 1, an SCD analysis unit 2 connected to the control unit 1, a signal receiving unit 3, and a signal sending unit 4; the input end of the signal receiving unit 3 is connected to the power communication link, and the output end is connected to the control unit 1. The input end of the signal sending unit 4 is connected to the control unit 1, and its output end is connected to the power communication link.

[0040] The test method of the GOOSE overall test device of the smart substation of this embodiment, such as image 3 As shown, including the following steps:

[0041] 1) Start the test device, the SCD analysis unit 2 reads the SCD file of the tested smart substation, and analyzes and classifies the GOOSE information in the SCD file. The above GOOSE information includes AppID, GOID, GOCBRef, DataSet, MinTime, MacAddr, and smart substation The GOOSE subsc...

Embodiment 2

[0047] Such as figure 2 As shown, the GOOSE overall test device for the smart substation of this embodiment is an improvement on the basis of the first embodiment. On the basis of the first embodiment, a file verification unit 5 for verifying the integrity and legality of the SCD file and The graphic display unit 6, wherein the file verification unit 5 is connected to the SCD analysis unit 2, and the graphic display unit 6 is connected to the control unit 1.

[0048] Because GOOSE subscription and digital secondary circuit are both logically related, which is far from the sensory concept of the traditional secondary circuit of the power system, the graphical display unit 6 can intuitively display the logical relationship between GOOSE subscription and digital secondary circuit, thereby facilitating users The use of and the addition and modification of logical relationships.

[0049] As each manufacturer implements the SCD file differently, the test device does not completely rely ...

Abstract

The invention relates to a GOOSE overall test device for an intelligent substation and a test method for the test device, belonging to the technical field of power system detection. The device includes a control unit, an SCD analysis unit connected with the control unit, a signal receiving unit for receiving GOOSE messages and a signal sending unit for sending analog GOOSE messages. In this test method, after the SCD analysis unit constructs the simulated GOOSE message basis of the virtual terminal, and the actual value of the virtual terminal in the power communication link obtained by the signal receiving unit, the simulated GOOSE message for the test is composed, and the simulated equipment and requirements are generated. The logical relationship of the virtual terminal value change of the test device is used as the basis for manual judgment. The test device of the invention uses the SCD file of the intelligent substation to simulate the GOOSE message and the GOOSE subscription relationship of the whole station, and can test on the spot.

Description

Technical field [0001] The invention relates to a test device of an intelligent substation, and at the same time relates to a test method of the test device, and belongs to the technical field of power system detection. Background technique [0002] With the promulgation of the IEC61850 standard and the popularization and application of related projects, tripping and interlocking solutions using the GOOSE mechanism have gradually been widely used in smart substations, and even part of the analog information and time synchronization information are also transmitted through GOOSE. The GOOSE soft message transmitted via Ethernet replaces a large number of cables used in the traditional secondary loop, which brings great convenience to engineering design and implementation. [0003] However, in actual engineering applications, since the traditional secondary circuit is directly connected by cable, it is intuitive and clear, while the GOOSE communication mechanism requires the informati...
