| Abstract: | The definition, classification of electronic transformer and connection mode of MU are introduced. According to the transformer configuration principle of interval-oriented implementation of transformer, the electronic transformer configuration scheme of 3/2 main wiring mode is put forward, combined with the characteristics of IEC 61850 standard protocols and process layer of digital substation. It is pointed that, by using the interval--oriented distributed bus protection scheme, the logic functions of CU could be simplified and the reliability of the bus protection could be enhanced. |
