Embodiment Construction

[0050]In order to make the purpose, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the following description The embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0051] Such as image 3 As shown, the conventional test method of the existing smart substation is to test the relay protection function and the transmission switch by adding fault data to the local smart cabinet in the high-voltage site. The information direction of the fault quantity is as follows: the analog relay p...

Abstract

The invention provides a portable SV/GOOSE common network maintenance isolation device and method. The portable SV/GOOSE common network maintenance isolation device comprises a forwarding module, a management module, a power supply module and a transmission module, wherein the transmission module is used for receiving and sending an SV message and a GOOSE message, the forwarding module is used for forwarding the SV message from a relay protection tester to a relay protection device according to a message management strategy, and then forwarding the GOOSE message generated by the relay protection device to an intelligent terminal, the management module is used for configuring the message management strategy, and the power supply module is used for providing a power supply for the safety maintenance isolation device. According to the invention, the SV/GOOSE message is forwarded among the relay protection tester, the relay protection device and the intelligent terminal through the forwarding module and the transmission module, so that physical decoupling with a running process layer network is realized, and the problems of protection device maloperation or switch collapse caused by transmission of fault quantity in a switch when fault quantity is added to the process layer switch in prior art are solved.

Description

technical field [0001] The invention belongs to the technical field of intelligent substations, and in particular relates to a portable SV / GOOSE shared network maintenance and isolation device and method. Background technique [0002] In recent years, China Southern Power Grid has begun to vigorously promote the construction of smart substations. Compared with conventional substations, the most notable feature of smart substations is the use of a small number of optical cables instead of a large number of cables to maximize information sharing and network the secondary system; a large number of maintenance and commissioning of relay protection equipment in smart substations. [0003] For smart substations that adopt network mining and network jumping, when the relay protection equipment is overhauled and debugged, since the process layer switch equipment belongs to the running equipment, in order to avoid fault data being broadcast in the switch, causing protection malfuncti...
