Embodiment 1

[0027] In this embodiment, a unified modeling of the access control system in the substation is proposed, and parameter setting, operation control and status monitoring of the substation access control system are realized through the access control management system.

[0028] In this embodiment, an access control management system is composed of an access control system local module and a remote workstation installed in the substation, thereby realizing the management of the access control equipment of the substation. In this embodiment, the remote workstation, the on-site module of the access control system, and the access control device interact through a file transfer service, and the file transfer service adopts the IEC61850 communication protocol.

[0029] In this example, if figure 1 As shown, in this embodiment, the access control equipment in the substation mainly includes the access control controller, the door and the access control card. An access controller manage...

Embodiment 2

[0056] In order to realize the data synchronization between the remote workstation and the host, and realize the reliability of the operation and maintenance of the substation system, the difference between this embodiment and the above-mentioned embodiment 1 of the substation access control management system is that in this embodiment, the remote workstation includes an auxiliary Control workstations and auxiliary control hosts, and therefore also include file synchronization between auxiliary control workstations and auxiliary control hosts.

[0057] Such as image 3 , 4 As shown, the auxiliary control workstation creates a corresponding request file according to user needs, and synchronizes the request file to the auxiliary control host, and the auxiliary control host downloads the request file to the local module of the access control system, that is, the forward synchronization process .

[0058] The on-site module of the access control system generates a corresponding ...

Embodiment 3

[0068] In order to improve the fluency of the data interaction process and improve the interaction efficiency, in this embodiment, the above-mentioned file transfer service is also provided with a waiting call wake-up function:

[0069] As an implementation, in this example, as image 3 As shown, after the response file is successfully created, the on-site module of the access control system actively sends a file generation report to the remote workstation, notifying the remote workstation that the response file is ready, and the remote workstation sends a call response to the on-site module of the access control system file, the on-site module of the access control system uploads the response file according to the call response file.

[0070] As another implementation, in this embodiment, the on-site module of the access control system starts timing after receiving the request file. The local module of the system uploads the response file according to the call response file....

Abstract

The invention relates to a transformer substation access control management system based on file transmission. The invention belongs to the comprehensive technical field of computer technology and power system automation technology. An access control system on-site module is used for based on access control equipment information associated with the access control system on-site module, instantiating an access control standardized model established by a remote workstation, uploading the instantiated model to the remote workstation, receiving a request file issued by the remote workstation, generating a corresponding response file for the request file, and returning the response file to the remote workstation; the remote workstation creates a corresponding request file according to user requirements, downloads the request file to an access control system on-site module, receives a response file returned by the access control system on-site module, and analyzes the response file to complete service processing, thereby solving the problem that an upper-layer workstation in a transformer substation cannot effectively monitor and control an access control system in time in the prior art.

Description

technical field [0001] The invention relates to a substation access control management system based on file transmission, which belongs to the comprehensive technical field of computer technology and electric power system automation technology. Background technique [0002] With the development of power automation technology, the current power system has basically realized the operation and maintenance mode of centralized control center plus unattended substation. The centralized control center is responsible for the operation and maintenance of multiple substations in a region. After the State Grid Corporation implements the "overhaul" operation mode of the power grid, the geographical span of substations under the responsibility of a centralized control center can reach hundreds of kilometers, and the door opening problem of unattended substations has become an important aspect that affects work efficiency. [0003] In addition, the current power system automation is main...
