Example Embodiment

[0022] The present invention will be further explained below in conjunction with the drawings. The method of the present invention divides the auxiliary production system of the substation into three layers. The first layer is the remote centralized control station management host, the second layer is the station host, and the third layer is the auxiliary production subsystems of the substation composed of intelligent sensor networks. The IEC61850 protocol unifies these three-layer devices into a large system (such as figure 1 Shown).

[0023] The remote centralized control station management host and the station control host are composed of workstations, databases and corresponding software. The auxiliary production subsystem includes the following six subsystems:

[0024] Substation image monitoring subsystem;

[0025] Substation security guard subsystem;

[0026] Substation fire alarm and fire protection subsystem;

[0027] Substation heating and ventilation subsystem;

[0028] Sub...

Abstract

The invention relates to a coordination linkage method of an intelligent transformer substation assisting production system, which is characterized by comprising the following steps of: 1, establishing a mapping relation; 2, capturing and analyzing a GOOSE message; 3, finding a sensor related to a GOOSE event according to the mapping relation, coordinating and sensing by a plurality of sensors, re-checking an image, and determining the event; 4, calling a control function related to the event to realize that the coordination linkage is completed by switching a video channel and starting or shutting terminal equipment; and 5, sending an event processing report to a remote centralized control station through a network by adopting an IEC61850 protocol, and receiving a manual intervene command to an operator in charge of the remote centralized control station. The method ensures that all auxiliary production devices of a transformer substation can realize automatic coordination linkage, reduces manual intervene, and ensures no erroneous judgment and false tripping by adopting a multi-sensor coordination sensing and intelligent image recognition technology, thereby achieving the purpose of realizing intelligent operation management on the transformer substation assisting production system.

Description

technical field [0001] The invention relates to a method for coordination and linkage within and among auxiliary production systems such as image monitoring, security guards, fire alarm, fire protection, water supply and drainage, heating and ventilation in an intelligent substation, and belongs to the field of electrical technology. Background technique [0002] At present, most of the auxiliary production systems such as image monitoring, security guards, fire alarms, fire protection, water supply and drainage, heating and ventilation installed in substations are small automation devices that are independent and do not have dialogue functions. All devices cannot be linked, requiring manual attention, understanding and processing of information from each device. Although some auxiliary production systems use hard-contact connection to achieve simple linkage, there are disadvantages such as low level of intelligence in linkage, susceptibility to sensor failure and environmen...
