Problems solved by technology

The focus of this method is to detect the correctness and standardization of the SCD file and the ICD file of each manufacturer, and whether it complies with the IEC61850 standard. It cannot solve the consistency problem between the SCD file of the whole station and the device CID file, and cannot realize online detection.

Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0024] Taking the substation monitoring system adopting the IEC61850 standard as an example, the process of the online detection method for the consistency between the SCD and IED models is as follows: figure 2 As shown, the specific implementation process of verification is:

[0025] (1) First load the SCD analysis information, if the loading fails, the verification fails, and the entire detection process ends; then get the reference name (reference) of the IED device to be detected, and search in the IED information analyzed by the SCD according to the reference of the IED, If the reference name does not exist, the verification fails, and the IED detection process ends;

[0026] (2) Obtain ...

Abstract

The invention belongs to the field of power automation and relates to a monitoring system software technology for power system automation based on IEC61850. In a monitoring system of a transformer substation monitoring system adopting the IEC61850 standard, because the SCD (System Configuration Document) and the CID (Case Instance Document) model document in the device are required to be frequently modified, the condition that the SCD is inconsistent with a CID model document actually running in an IED (Intelligent Electronic Device) occurs sometimes during the implementation of the system integration or the extension transformation. The invention provides the method for detecting the consistency of the SCD and the IED model on line. After the electricity initialization is carried out on the IED, the check process is automatically executed by a background monitoring system, or all IEDs can be analyzed from the SCD and checked one by one, thereby the consistency check of all SCDs and models of all IEDs in the whole substation can be realized. By using the method for detecting on line, the problem that the SCDs are inconsistent with the IED models in the whole substation can be solved and the consistency of monitoring system information can be ensured.

Description

technical field [0001] The invention belongs to the field of electric power automation, relates to the monitoring system software technology of the electric power system automation based on IEC61850, and provides a substation monitoring system based on the IEC61850 standard to check the consistency between the SCD model file of the whole station and each IED model when the system is integrated. online detection method. Background technique [0002] At present, the IEC61850 technical standard has been widely promoted and applied in the substation monitoring system. More and more intelligent secondary equipment (IED) adopts the system standard of IEC61850 for design and application. According to the IEC61850 standard, when implementing system integration in the substation monitoring system, the IED manufacturer first needs to provide a device template configuration file (ICD) that is consistent with its own device, and then the system integration manufacturer uses a unified c...
