Embodiment Construction
[0017] The present invention will be described in detail below with reference to the embodiments and the accompanying drawings.
[0018] The method of the present invention comprises the following steps:
[0019] 1. Establish a mapping relationship
[0020] This link establishes the mapping relationship between the number of each camera (cameraID) and each preset position (cameraPreset, including orientation, observation angle and focal length, etc.) and the GOOSE variable list member (allData) representing the content of the GOOSE event.
[0021] Establishing the mapping relationship between the camera number / preset position and the variable list members requires the camera installation configuration information and the system configuration description (System Configuration Description, SCD) file of the substation.
[0022] Step 1: According to the corresponding relationship between the camera and the controlled or associated secondary device, establish the correspondence be...

The invention discloses a protection and video system linkage control method of a digital transformer substation of an electric power system. The method comprises the following steps: establishing a mapping relation, capturing and analyzing a GOOSE message, turning on a lighting installation, starting a video recorder, switching a video channel, as well as alarming and realizing the protection and video system linkage. The protection and video system linkage control method comprises the following steps: finishing establishing the mapping relation, acquiring and analyzing the GOOSE message by a software programming manner or adding a communication server dedicated for realizing GOOSE linkage; sending control commands of positioning the video recorder, video recording, switching the video channel and the like to a video processing unit by a network according to a remote transmission protocol of a remote vision system; and finishing the protection and video system linkage function. The method is suitable for the digital transformer substation, utilizes the most important communication service of the digital transformer substation, namely a general object-oriented transformer substation event, and independently finishes the linkage function of a secondary system and a video control system without dependence on an integrated automation system.
Description
technical field [0001] The invention relates to a power system, in particular to a protection and video system linkage control method for a digital substation of the power system. Background technique [0002] The Remote Video Surveillance System for Substation (RVSS) can not only provide real-time images of the operating conditions of various equipment in the substation for distant places, realize the visual monitoring and scheduling of the power grid, and improve the safety and reliability of the operation and maintenance of the substation; It can record all kinds of accident and alarm information at the scene, and provide first-hand information for accident analysis. Therefore, RVSS has become a necessary construction project for unmanned or even manned substations. like figure 1 As shown, at present, the traditional substation remote viewing system RVSS architecture mostly adopts the system architecture of centralized management and hierarchical control, which can be r...
