Embodiment Construction

[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0022] In the present invention, the relay protection device of the intelligent substation is provided with a safety isolation control device, and the safety isolation control device realizes the function of safety isolation of the relay protection device. As for other components in the relay protection device, they belong to the prior art and will not be described in detail here.

[0023] The optical interface module in the relay protection device also belongs to the conventional technology, which will be briefly introduced below.

[0024] Normally, the optical port modules of relay protection devices are divided into two categories, one is the receiving optical port module, which is used to receive external data information, and the other is the sending optical port module, which is used to send data information to the outside world. . And, a receiving op...

Abstract

The invention relates to a relay protection device and a safety isolation control method and a control device thereof. The relay protection device comprises a safety isolation control device, wherein the safety isolation control device and the control method are respectively applicable to an intelligent transformer station; an optical port receiving and sending safety isolation module is arranged in the control device; during the safety isolation, a control instruction of stopping the operation is sent to a corresponding optical port module; the corresponding optical port module is controlled to stop operation; the safe isolation of the rely protection device is realized. The control device has the advantages that during the safety isolation, the number of times of plugging and unplugging optical fiber when an optical port of the relay protection device is isolated can be reduced; the misoperation risk on the relay protection device is reduced; the service life of the optical port of the device and the service life of optical fiber are prolonged; the reliable transmission of information is guaranteed.

Description

technical field [0001] The invention relates to a relay protection device, a safety isolation control method and a control device thereof, and belongs to the technical field of relay protection of electric power system intelligent substations. Background technique [0002] Smart substation is an important part of a strong smart grid. The relay protection device in the station is quite different from the traditional substation in terms of information receiving, sending and processing methods, and higher requirements are put forward for its reliability when it is isolated from the outside. . Compared with the traditional substation, the relay protection device of the smart substation mainly relies on its own optical port to send and receive information, and transmits information in the form of optical signals, and replaces most of the hard pressure plates with soft pressure plates, so that the device isolation method has undergone major changes. Variety. [0003] Since the r...
