Problems solved by technology

Since the verification rules of ICD files are relatively broad, each smart device manufacturer is allowed to add data set members, instantiated nodes, and self-defined nodes under the permission of IEC61850 rules, and simply use one ICD model as a benchmark template to verify another The accuracy of an ICD model will be greatly reduced. In addition, the ICD file structure is complex and difficult to expand, which cannot solve the problem of continuous changes in model verification requirements.

Embodiment Construction

[0023] The technical scheme of the present invention is described in detail below in conjunction with accompanying drawing:

[0024] Such as figure 1 , a method for verifying an ICD model of a substation intelligent device based on a rule file, comprising the following steps:

[0025] S1: Select the ICD model to be verified, use the standard XML parsing library (class) to verify whether the ICD model of the smart device conforms to the XML grammar rules, ensure that all XML elements must have closing tags, XML must be correctly nested, and XML documents must There is root element etc. For ICD model files that do not conform to the XML format, the subsequent steps will be skipped, an error result message will be given directly and the verification process will end.

[0026] S2: For the ICD model verified by step S1, use the schema rule file defined in the IEC61850 standard, and use the standard schema verification library (class) to verify whether the general syntax and seman...

Abstract

The invention discloses a checking method for an ICD model of an intelligent device of a transformer substation based on a rule file. The checking method comprises the following steps: performing XML format legality checking on the ICD model of the intelligent device by using an XML analysis library; performing grammar and semantic checking on the ICD model of the intelligent device by using a schema rule file of IEC61850; selecting an existing or newly defined intelligent device ICD model normative checking rule file, analyzing the verification rule file to form a verification rule data structure, and performing model normative checking on the intelligent device ICD model by using the verification rule data structure; and outputting a verification result. According to the method, on the premise that the application program is not changed, the new verification requirement is met by newly adding or revising the rule file, the repeated development workload of the verification tool is reduced to the maximum extent, and it is ensured that the same checking tool continuously adapts to the constantly-changing verification requirement of ICD model verification of multiple types of intelligent devices.

Description

technical field [0001] The invention relates to a method in the field of electric power system, in particular to a verification method of an ICD model of a substation intelligent device based on a rule file. Background technique [0002] The communication basis of the smart substation is the IEC61850 model system. If the smart devices running in the station want to access the network in the station, they must abstract their own capability descriptions into ICD models and provide them to the design institute or smart station commissioning unit, which will be generated according to the actual design and configuration of the substation site. SCD model, and then transfer the SCD model or its derived models (CID, CCD, etc.) to the smart device to complete its engineering configuration. It can be seen that ensuring the standard and normativeness of the ICD model of the smart device is the prerequisite for promoting the interconnection and interoperability of the IEC61850 protocol....
