Problems solved by technology

The virtual circuit describing the direction of the signal flow is closely related to the physical connection real circuit that actually carries the signal flow. In engineering practice, it is often necessary to know which optical fibers a certain signal flow passes through or which signal flow is carried by a certain optical fiber. At present, there is no intuitive way show this information

Embodiment Construction

[0030] In order to make it easier for those skilled in the art to understand and implement the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0031] figure 1 It is a tree structure diagram of the SCD file of a smart substation. The SCD file mainly includes five parts: Header, Substation, Communication, IED, and DataTypeTemplate. Communication and IED are two parts related to the secondary virtual and real circuit. The Communication section describes the communication parameter configuration of each IED; each IED represents an intelligent electronic device (such as a relay protection device, a measurement and control device, etc.) Nodes and data objects, and communication services that devices can provide.

[0032] figure 2 It is a schematic diagram of the relationship between the virtual line and the physical line between two IEDs. The physical connection refers to...

Abstract

The invention relates to a visualized display method for a relay protection secondary virtual or true circuit of an intelligent transformer substation. The method comprises the following steps: resolving an SCD (Security Coding Device) file of the intelligent transformer substation, extracting SV / GOOSE message configuration information of each IED, external data reference information and physical port configuration information; analyzing external reference entries of each IED, and constructing a virtual connection line; analyzing physical port configuration information of each IED, and constructing a physical connection line between ports; finding out physical ports, relevant to each output virtual terminal and each input virtual terminal, of each IED; and drawing a secondary virtual or true circuit diagram. The method can be used for displaying a secondary virtual or true circuit diagram, greatly facilitating checking of a relay protection secondary circuit of the intelligent transformer substation, and obviously improving the secondary virtual or true circuit inspection efficiency.

Description

technical field [0001] The invention relates to the technical field of visualization of SCD files in intelligent substations, in particular to a method for visualizing and displaying secondary virtual and real circuits of relay protection in intelligent substations. Background technique [0002] At present, the construction of a new generation of smart substations in my country is in full swing, and the most important thing in smart substations is the use of digital methods to build communication network systems for secondary equipment. Series of standards and other standards derived from this series of standards. DL 860 stipulates an SCL file to describe the configuration of the substation. The SCL file is divided into 4 categories, namely the SSD file describing the substation specification, the ICD file describing the IED capability, the SCD file describing the complete configuration of the whole station, and the CID describing the configuration of a single IED. document....
