Description
Technical Field
The invention relates to a power relay protection system, in particular to an automatic generation system of a relay protection device capability description file.
Background
In recent years, the strong smart grid construction in China has made great achievements, and powerful guarantee is provided for the development of the economic society. The intelligent electronic equipment relay protection device taking the IEC61850 standard as a core is widely applied, so that the digitization, networking and intelligence levels of a power grid are greatly improved while the power grid guards a safety defense line.
The IEC61850 standard is widely accepted in China due to the characteristics of functional perfection and interoperability, the realization of the interoperation and information sharing among intelligent electronic devices is the final purpose of the IEC61850 standard, the core requirement for realizing the interoperation is the unification of an information model and an information exchange mode, and an information exchange method is determined to a great extent by accurately defining (standardizing) the information model. Therefore, the information model of the relay protection device based on the IEC61850 standard and the modeling method thereof are the foundation for realizing interoperability and digitalization and intellectualization of the relay protection device.
An information model of the relay protection device described based on the IEC61850 standard is called an ICD (interface control document) file for describing the capability of the relay protection device. The ICD file describes the functional and engineering capabilities of the IED, including self-describing information of the intelligent electronic device model. The ICD file is modeled according to information models provided in IEC61850-7-4 and information parameters and model requirements refined in Q/GDW1396-2012 IEC61850 engineering relay protection application model, and is compiled according to SCL coding specifications defined in IEC61850-6, and finally a model description file for representing the actual capacity of the relay protection device is formed: and (5) a relay protection device capability description file.
The relay protection device capability description file is used as a core file for realizing digitization and intellectualization of intelligent electronic equipment, and the generation methods in the prior art mainly comprise two types: manual authoring and tool configuration generation. And manually writing by using an XML editing tool such as notepad and xmlspy by a developer. Because the ICD file has a complex structure and a plurality of contents, a conventional intelligent electronic device for line protection usually has tens of thousands of lines of codes and millions of bytes, and the manual writing is extremely complex, easy to make mistakes and low in efficiency, and needs to have a high professional level and high labor cost. And (4) tool configuration generation, namely, completing model file configuration of the relay protection device on a Personal Computer (PC) through an independent tool, and generating an ICD (interface control document) file of the relay protection device by the tool. The tool configuration generation has the advantages of no need of manual writing and modification, high efficiency, difficulty in error, configuration by professional technicians, no need of configuration and manual intervention and low efficiency. Moreover, since the configuration of the intelligent electronic device can only be completed offline, after the relay protection device is sent to a field for instantiation, partial protection functions need to be switched off due to different field operation modes, so that the ICD file configured offline is not completely consistent with the capability of the device actually operated on the field, information is inconsistent, and secondary modification is often performed manually on the field; in addition, under the condition of generating by adopting tool configuration, if important basis for writing ICD, such as revision of Q/GDW1396-2012, affects format and content requirements of finally formed ICD, developers need to synchronously upgrade the generating tool to meet the requirements of revised specifications, but the code of the tool is complex to modify, and cannot flexibly respond to the change requirements of the specifications, so that ICD files meeting the requirements of the standard specifications and accurately expressing the capacity of the relay protection device are rapidly generated.
