Embodiment 1

[0021] The wide-area message management consists of a wide-area message subscription client, a wide-area message management center, and a wide-area subscription information sharing memory module.

[0022] The invention provides a method for managing wide-area messages in a power system, figure 1 It is a schematic diagram of its functional module structure, such as figure 1 As shown, the wide-area message management center is deployed on the distributed proxy server of each dispatching organization, and in each dispatching organization, the wide-area message subscription client processes the subscription / unsubscription request of the local application and forwards it to the wide-area message Domain message management center, and update client subscription information shared memory;

Embodiment 2

[0031] figure 2 It is a schematic diagram of the wide-area message management mechanism, such as figure 2 As shown, the wide-area subscription client is responsible for processing the subscription / unsubscription request of the application and forwarding it to the wide-area message management center of the proxy node. The local subscription processing module of the wide-area message management center processes and updates the local subscription information shared memory. The wide-area subscription processing module is responsible for synchronizing the data in the shared memory of wide-area subscription information between scheduling agencies. The key technologies involved in the whole process are subscription information heartbeat, subscription information detection, and subscription information synchronization.

Abstract

The invention discloses a wide area management method for an electric system. A wide area message management center is deployed on a distributed proxy server of each scheduling mechanism, and in each scheduling mechanism, a wide area message subscribing client processes a subscribing/unsubscribing request of a local application, forwards the subscribing/unsubscribing request to the wide area message management center, and updates a subscribing information shared memory of the client; and the wide area message management center receives and processes the subscribing request of the wide area message subscribing client, updates a local subscribing information shared memory, and synchronizes data of a wide area message subscribing information shared memory among different scheduling mechanism. According to the method of the invention, the problem that a unified message transmission model is lacked among the different scheduling mechanism is solved, a message transmission mechanism based on a subscribing/releasing mode among the scheduling systems in a wide area range is provided, and real-time push and collaborative sharing of various real-time messages across the scheduling mechanisms are effectively supported.

Description

technical field [0001] The invention relates to the field of power system communication, in particular to a method for managing wide-area messages in a power system. Background technique [0002] In the current smart grid dispatching control system, the message bus undertakes the message management and transmission functions, effectively supports the information interaction of data collection, data processing, accident inversion, public service and other applications, and realizes the on-demand and fast delivery of messages . However, the current message bus is still limited to the local area of ​​a single dispatching automation system. For real-time messages that need to be shared among multiple dispatching systems, such as power grid status information, important alarm events, etc., there is a lack of unified and efficient cross-dispatch system real-time Message management and transmission methods, research on general and efficient wide-area message management mechanisms,...
