Problems solved by technology

[0003] However, in the IEEE802.1Q standard, the standard only defines the GMRP protocol message type and parameter setting, and does not give the corresponding test method. This poses great difficulties for the assessment of GMRP equipment in smart substations, and it is impossible for this type of product Make an effective evaluation

Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0030] Such as figure 1 As shown, a test system for the performance of the GMRP protocol in a smart substation, including a relay protection tester, an overcurrent quick-break protection device, a busbar / main transformer protection device, the first GMRP switch under test, the second GMRP switch under test, and packet filling tester.

[0031] Both the relay protection tester and the overcurrent quick-break protection device are connected to the first GMRP switch to be tested, the first GMRP switch to be tested is connected to the second GMRP switch to be tested, and the bus / main transformer protection device is connected to the second GMRP switch to be tested. The connection of the tested GMRP...

Abstract

The invention discloses a GMRP protocol performance test system in an intelligent substation. The system comprises a relay protection tester, an overcurrent instantaneous trip protection device, a bus / master transformer protection device, a first tested GMRP switch, a second tested GMRP switch and a data throughput tester. Moreover, the invention discloses a test method of the system. According to the method and the system, practical application is simulated in a true network; the test method is comprehensive and accurate; the function and performance of the GMRP network switches in the intelligent substation can be quantitatively checked; therefore, the switches are completed; the product quality is improved; and an effective detection method and a tool are provided for a special detection mechanism or a device manufacturer.

Description

technical field [0001] The invention relates to a test system and method for the performance of the GMRP protocol of an intelligent substation, and belongs to the technical field of testing the Ethernet communication equipment and the GMRP protocol. Background technique [0002] Due to the deep root of Ethernet technology, Ethernet technology is widely used in the field of industrial automation, and people's demand for network equipment and technology is becoming more and more obvious. A dynamic Layer 2 multicast protocol GMRP technology conforming to IEEE802.3Q has begun to be applied in smart substations. This technology can dynamically learn Layer 2 multicast data and automatically receive it. engineering cost. [0003] However, in the IEEE802.1Q standard, the standard only defines the GMRP protocol message type and parameter setting, and does not give the corresponding test method. This poses great difficulties for the assessment of GMRP equipment in smart substations, ...
