The Design Of Transformer Smart Electronic Equipment According To IEC61850

IEC 61850 standard is an international standards which is applications in substation communication networks and systems by the International Electrotechnical Commission Technical Committee 57, promulgated in 2004. In the current power system, the requirements of substation automation have become increasingly, you need a universal means of communication to achieve to facilitate the management of substation and various IED interconnection between devices. IEC61850 proposes a common communication standard, through a series of Standardization, to form a standard output and achieve the system Seamless connection.IEC 61850-based intelligent electronic measuring equipment for transformers have many excellent performance. Follow a uniform protocol to communicate between devices and equipment more easily and conveniently, Smart devices for the IED from different manufacturers to interoperate and integrate seamlessly to provide an effective way.To accustom the rapid development of substation automation technology,on the base of data pro-type of UCA2.0 and according to many concerned standards, IED make the first whole international communication standard system on substation automation system, that is, IEC61850. By adopting modeling object-oriented, abstract communication service interface and XML technology, and by introducing the mechanism of specific communication service mapping, the standard can keep up with the rapid development of communication technology without losingits stability. The main work is as follows:This thesis introduces the partial discharge measurement, oil chromatography measurement, core grounding current measurement, the measurement methods and the importance of the casing.Based on the 220kv oil-immersed transformers measurement requirements of its model, detailed definitions of the various monitoring functions related to the logical node and the data objects of logical node, provides access to data services.This thesis describes the core of IEC61850:mms core services, the sending and receiving packets of smv and goose message. And shows a system structure of transformer line monitoring from the acquisition layer, communication layer, the data layer to application layer.Engineering practice shows that IEC 61850-based intelligent electronic measuring equipment for transformers have more compatible with electronic measuring devices, more convenient in interoperability, more powerful in data processing and so on than the conventional electronic measuring equipment.
