Problems solved by technology

As a result, the verification method is not intuitive and the probability of error is high;
[0004] Moreover, the model configuration file of the device changes due to reasons such as update, modification, upgrade, etc., which affects the potential possibility of virtual terminal connection between devices, and then affects the final configuration file downloaded to the device; due to the lack of effective verification methods, the substation Operation and maintenance or commissioning personnel can only re-test the device to ensure the correctness of the virtual terminal connection between the devices, thus greatly increasing the construction and commissioning cycle of the intelligent substation

Embodiment Construction

[0018] In order to facilitate understanding of the present invention, the following will be described in conjunction with the accompanying drawings.

[0019] Such as figure 1 As shown, a substation virtual terminal connection configuration verification method proposed by the present invention, the specific process is as follows:

[0020] S101. Extract the connection configuration information of the IED virtual terminal from the SCD file;

[0021] In order to realize the verification of the connection configuration of virtual terminals in intelligent substations, it is first necessary to extract the connection configuration information related to the IED (Intelligent Electronic Device, Intelligent Electronic Device) as a unit.

[0022] The virtual terminal configuration connection between IEDs reflects the corresponding relationship between the sending and receiving of GOOSE and SV transmission control information in the communication network. The SCD (Substation Configuratio...

Abstract

The invention provides a method for verifying connection configuration of a transformer substation virtual terminal. The method comprises steps: extracting connection configuration information of an IED (intelligent electronic device) virtual terminal from an SCD (substation configuration description) file; using the connection configuration information of an IED virtual terminal to generate an identifier, the identifier uniquely identifying virtual terminal configuration information of the present IED; and using the identifier to verify the connection configuration of the IED virtual terminal. The invention also provides a device for verifying connection configuration of the transformer substation virtual terminal. The device can improve design of an intelligentized transformer substation and efficiency of operating maintenance, reduce operation management error risk of a digitalized transformer substation, and ensure safety operation of an electric power system.

Description

technical field [0001] The invention relates to the field of substation safety detection, in particular to a method and device for verifying connection configuration of substation virtual terminals. Background technique [0002] Compared with traditional substations, due to the introduction of virtual terminal connections in intelligent substations, there is a prominent problem that needs to be solved urgently, that is, there is a lack of effective means to verify the correctness of virtual terminal connection configurations. In traditional substations, the connections of device terminals and signal cables and control cables are all visible, and it is easy to complete interval maintenance and transformation; in smart substations, virtual terminals / virtual wires are used instead of physical terminals and metal wires. To specify the communication link and data flow between devices, the configuration file of the smart substation that has been piloted is in an unprotected state,...
