Standby device of station level and physical device of transformer substation and automatic online method thereof

Abstract

The invention relates to a station level of a transformer substation, a standby device of a physical device and an automatic online method thereof, belonging to the technical field of communications.The standby device comprises a management module and a virtual module serving as a standby of the physical device. Each virtual module is configured with a CID engineering file and a CCD engineering file which are the same as those of a corresponding entity device, and each virtual module acquires a GOOSE message sent by the entity device from a GOOSE network of a station control layer through themanagement module; the management module judges the link state of the physical device according to the received GOOSE message sent by the physical device, and controls the corresponding virtual module to exit when the physical device is in the connection state; and the corresponding virtual module is controlled to be input when the virtual module is in the broken link state. According to the invention, the standby function of all physical devices in the station level can be realized by using one standby device, the hardware cost is greatly reduced, the standby device can quickly and effectively realize the automatic switching of the input and exit states of the virtual module according to the states of the physical devices, and the practical value is very good.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a station control layer of a substation, a backup device of a physical device and an automatic online method thereof. Background technique [0002] In the prior art, in order to ensure the normal operation of the station control layer of the digital substation (or smart substation), the physical device of the station control layer is generally equipped with a corresponding backup physical device for when the link of the main physical device is disconnected , put into the standby physical device, so as to realize the normal operation of the station control layer. However, because there are too many physical devices in the station control layer, the cost of configuring a backup physical device is too high. [0003] In addition, because the 61850 station engineering configuration workload is relatively large, the centralized device is configured according to the u...
