[0004] In order to solve the problem that the content transmitted by the above-mentioned traditional substation is limited to "four remote" data, which has caused a bottleneck in the use of data between the upstream substation and the downstream control center, a large amount of data in the substation except the "four remote" is stranded in the station, and it is difficult to provide sufficient data support To deal with the problems of complex large power grid operation analysis and accident analysis, the present invention provides a method for accessing between master and sub-stations of the power grid. The method includes:

Embodiment 1
[0049] Such as figure 1 Shown: An access method between the main and sub-stations of the power grid:
[0050] Step 1: The master station obtains the data service request from the dispatch center;
[0051] Step 2: Based on the data service request, obtain substation service location information, and send the data service request to the substation involved in the location information;
[0052] Step 3: The master station receives the data returned by the sub-station according to the service request, and sends the data to the dispatch center that initiated the data service request.
[0053] Combine below figure 2 , image 3 A detailed explanation of the above steps
[0054] Explanation for step 1: The real-time transparent access tool between the main and sub-stations of the power grid uses Internet technology to realize the service-oriented transparent access of the main and sub-stations, enabling the substation control layer, bay layer devices, and various applications of t...
Embodiment 2
[0067] The present invention also relates to an access system between main and sub-stations of the power grid, including:
[0068] Transparent access client: the transparent access client is set at the master station, including: a service access interface module;
[0069] The service access interface is used to: obtain the data service request of the dispatch center;
[0070] Information acquisition module: based on the data service request, obtain substation service location information, and send the data service request to the substation involved in the location information;
[0071] Data acquisition module: the main station receives the data returned by the sub-station according to the service request, and sends the data to the dispatch center that initiated the data service request.
[0072] Also includes transparent access to the server side;
[0073] The transparent access server is set at the substation, and includes: an application service interface module.

Abstract
The invention relates to an access method and system between master stations and substations of a power network. The method comprises the steps that transparent access servers of the substations register provided service with a global service manager in advance; on the basis of the service registered by the transparent access servers of the substations, the transparent access servers of the substations receive data service requests sent by a dispatching center through utilization of real-time transparent access clients of the master stations; the transparent access servers of the substations search requested data from virtual data pools according to the received data service requests and return the searched data to the master stations, and moreover the transparent access clients of the master stations return the data to a dispatching center business application. According to the access method and system between the master stations and the substations of the power network provided by the invention, the problem of data employing bottleneck between upstream transformer substations and downstream transformer substations resulting from the fact that content sent by transformer substations is only limited to telemetering, remote signal, remote control and remote adjustment data is solved, and sufficient all-type data support for complex big power network operation analysis and accident analysis is provided.
Description
technical field [0001] The invention belongs to the technical field of electric power dispatching automation, and in particular relates to an access method and system between main and sub-stations of a power grid. Background technique [0002] Reliable data interaction between the main and sub-stations of the power grid is an important guarantee for the stable operation of the dispatching and substation systems. With the advancement and deepening of the construction of smart substations, more new technologies and new equipment have been adopted in smart substations. The data interaction requirements between the master and sub-stations have developed from the initial simple "four remotes" to remote browsing and direct transmission of alarms. At the same time, the data interaction between control centers has also developed from simple data forwarding to a complex data exchange model represented by remote access. [0003] The traditional power grid data is forwarded step by st...
