1、IEC61850 外文翻译 外文文献 英文文献及翻译Modeling of Digital Protective Device According to IEC61850AbstractIEC 61850 is an international standard about substation constituted by the substation IEC TC57.It reflects the developments direction and automation tendency of automation, and arouses the widespread interes

2、t of the domestic and foreign power industry. The transformer is a core equipment in the substation its protection, measurement and control equipments are the main equipments of substation automation system. Therefore，it is significant for us to apply the IEC 61850 standard to the Digital transforme

3、rs protection, measurement and control.The background, the domestic and foreign present situations, the significance and the content of IEC 61850 are introduced in this paper, the analysis of IEC 61850 standards modeling process are described. Firstly, based on the function free distribution and the

4、 assignment concept of IEC 61850, the protection, measurement and the control unit are separated and the respective function is describe by the logical node. Secondly, according to the modeling approach and principle based on IEC 61850，the typical protection, measurement and the control logical node

5、s are taken as examples to complete modeling of logical nodes with UML. At last, the flow chart of the function realization is described and the flow of the function realization is discussed. In this foundation, the transformer differential protection IED is taken as an example to show the configura

7、al system through internal data communication, to realize the subsystems between subsystems and internal information exchange and sharing information, to reduce the substation second equipment configuration, and simplify the repeat of the subsystems of the interconnections, not only reduce repeated

8、investment, and also to improve the security and reliability of the system as a whole.But, the actual circumstance of each transformer substation be respectively each product supplier in order to fight, usage dissimilarity of communication code. Almost each produce a company should the company all h

Establishment IEC 61850 main purposes is make dissimilarity manufacturer of the product has with each other operability and make these product drive expediently integration to go in a system.According to IEC 61850 of definition, with each other operability is come fro
