Embodiment Construction

[0018] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings of the description.

[0019] figure 1 It is a functional schematic diagram of the method of the present invention, and the method of the present invention is completed through the following steps.

[0020] Step 1: The configuration conditions that should be determined before information flow configuration include: (1) The number of switches configured in the substation and the cascading relationship between switches. Each switch and each port of the switch are uniquely numbered. The cascading paths between switches need to indicate the switch numbers and corresponding port numbers at both ends. (2) The connection relationship between the devices in the substation and the switch. The devices and device ports in the substation are uniquely numbered. Each connection between the switch and the device needs to indicate the number of the con...

Abstract

The invention provides an automatic configuration method of switch information flow of an intelligent substation. The method is applied to the intelligent substation employing IEC 61850 for communications; the method is summarized from a great deal of communications integration practice of the intelligent substations, is highly universal and is suitable for communications configuration of substation networks different in voltage level and topological structure. By simulating propagation of actual running messages along with manual intervention, an efficient and flexibly static path with substation application messages as an index is planned for total station information flow. The method includes information flow path searching and information flow path correctness and completeness detecting; on such basis, the configuration method of information flows in reorganization and expansion of the intelligent substation is provided; the configuration process of the switch information flows of the intelligent substation is automated.

Description

technical field [0001] The invention belongs to the technical field of intelligent substation communication integration. The invention provides an automatic configuration method of switch information flow. According to the configuration requirement information provided by the electric power design institute or the substation monitoring system integrator, combined with the substation management specification to manually intervene in the direction of the information flow, A switch configuration file meeting the surveillance system integration requirements can be derived. When the substation is rebuilt or expanded, the information flow change path list can be obtained on the basis of the existing configuration, and the risk of switch configuration change can be reasonably controlled. Background technique [0002] Smart substations have been widely used in China, and the control cables and signal cables have been greatly simplified or canceled, and the communication problems bet...
