Description
Technical Field
The invention relates to a power relay protection system, in particular to an automatic generation system of a relay protection device capacity description file.
Background
In recent years, the construction of the strong smart grid in China achieves great achievement, and provides powerful guarantee for the development of economy and society. The wide application of the intelligent electronic equipment relay protection device taking IEC61850 standard as the core greatly improves the level of digitalization, networking and intellectualization of the power grid while protecting the safety line for the power grid.
The IEC61850 standard is widely accepted in China by the characteristics of functional perfection and interoperability, the realization of the interoperability and information sharing among intelligent electronic devices is the final purpose of the IEC61850 standard, the core requirement for realizing the interoperability is the unification of an information model and an information exchange mode, and the accurate definition (standardization) of the information model determines the information exchange method to a great extent. Therefore, the information model of the relay protection device based on the IEC61850 standard and the modeling method thereof are the basis for realizing the digitization and the intellectualization of the relay protection device.
The information model of the relay protection device described based on IEC61850 standard is called an ICD file for describing the capability of the relay protection device. The ICD file describes the functions and engineering capabilities of the intelligent electronic device IED, including self-description information of the intelligent electronic device model. ICD files are 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 models, and are written according to SCL coding specifications defined in IEC61850-6, and finally a model description file representing the actual capacity of the relay protection device is formed. Relay protection device capability description file.
The capability description file of the relay protection device is used as a core file for realizing the digitization and the intellectualization of the intelligent electronic equipment, and the generation method in the prior art mainly comprises two types: manual writing and tool configuration generation. Manual writing is done by a developer using an XML editing tool such as notepad, xmlspy. Because ICD file structure is complicated, the content is numerous, and a conventional circuit protection intelligent electronic device usually has tens of thousands of lines of codes, millions of bytes, and manual writing is extremely complicated, easy to make mistakes, low in efficiency, needs to have very high professional level, and has high labor cost. And the tool configuration is generated, the model file configuration of the relay protection device is completed on a personal computer PC through an independent tool, and then the ICD file of the relay protection device is generated by the tool. The tool configuration generation has the advantages of avoiding manual writing and modification, having higher efficiency and being difficult to make mistakes, still requiring professional technicians to configure, being incapable of avoiding configuration and human intervention, and still having low efficiency. In addition, the configuration of the intelligent electronic equipment can only be completed offline, so that after the relay protection device is sent to the field instantiation, partial protection functions are required to be switched on and off due to different field operation modes, the ICD file configured offline is not completely always in the capacity of the equipment actually operated on the field, and the situation that the information is inconsistent exists, and the secondary modification is often required to be carried out manually on the field; in addition, under the condition of adopting tool configuration generation, if important basis of writing ICDs, such as revising Q/GDW1396-2012, format and content requirements of the ICDs are finally formed, a developer needs to synchronously upgrade the generation tools, the requirements of revised specifications can be met, but the code of the tools is complicated to modify, the change requirements of the specifications cannot be responded flexibly, ICD files meeting standard specification requirements and accurately expressing the capability of the relay protection device are generated rapidly.
