Problems solved by technology

Due to the high price of electronic switches and the strict requirements on network channels, they cannot meet the needs of long distance, high image quality and fast response, and their application range is greatly limited.
The existing power grid dispatching system and substation monitoring system are provided by different suppliers, and the remote terminals provided by each manufacturer only support the self-produced substation system. At the same time, each independent system uses a different storage format for its graphics , which leads to the inability of direct interaction and information sharing of graphics and models between different systems
[0004] Based on the above problems, how to provide a method for remotely accessing substation graphics between heterogeneous systems to meet the needs of large data volumes, high browsing efficiency, and high stability, and to overcome the problem that graphics and models between heterogeneous systems cannot directly interact Technical problems that need to be solved by field personnel

Embodiment Construction

[0023] A method for remotely accessing substation graphics between heterogeneous systems of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0024] A method for remotely accessing substation graphics among heterogeneous systems of the present invention comprises the following steps:

[0025] 1) Establish a standard graphic file: the graphic file conforms to the power system graphic description specification, follows the CIM / G standard protocol, uses the G format to describe the content of the graphic file, realizes the interaction of power graphics and power equipment information between different systems, and solves the problem of Graphic files and device information sharing between heterogeneous systems;

[0026] 2) Request and response of file service: file service relies on the service bus, and the complex underlying network communication details are handed over to the service bus for processing. The main sta...

Abstract

The invention discloses a method for retrieving transformer graphs among heterogeneous systems. The method comprises the following steps of (1) establishing a standard graph file, (2) requesting and responding to a file service and (3) refreshing graphs. The step (2) further comprises the processes that a primary station sends a service request through a service bus, then a proxy server transmits the request to a remote transformer system through the DL 476 protocol, and the remote transformer system determines whether to send the file to the primary station system or not. The step (3) further comprises the processes that an SOA structure is adopted in the service bus, an uniform network transmission interface is provided, a graph refreshing service module establishes a corresponding frame cache and sends back frame data to a main machine of the primary station system according to a refreshing period, and browsers of the primary station system refresh the frame data, colors and states. The method can meet the requirements for browsing the transformer graphs of different systems remotely, and realizes remote monitoring to the running conditions of the heterogeneous transformer systems.

Description

technical field [0001] The invention relates to a method for remotely viewing substation graphics among heterogeneous systems. The method is used to meet the needs of a dispatch automation system for remotely browsing substation graphics of different systems, and belongs to the field of power grid dispatch automation.
