[Abstract]:As one of the important components of smart grid, smart substation is the key to connect the six links of smart grid generation, transmission, substation, distribution, power consumption and dispatching. Intelligent substation needs reliable measurement and accurate data. Electronic transformer is an ideal measuring equipment based on measurement, which meets the development requirements of intelligent substation in the future. The research on the application of electronic transformer in smart grid is of great significance for the reliable measurement and relay protection of smart grid. The main contents of this paper are as follows: Firstly, the demand of intelligent substation and its key equipment electronic transformer is analyzed. The key standards in intelligent substation, such as IEC61850 / goose technology, are summarized, and the problems existing in the application of electronic transformer are summarized. The influence of electronic transformer on intelligent substation and the relationship between electronic transformer and intelligent substation are analyzed. Secondly, taking Rogowski coil current transformer and capacitive voltage transformer as examples, the working principle of electronic transformer is introduced, and the influence of temperature on these two kinds of electronic transformer is analyzed. The temperature compensation of Rogowski coil current transformer is studied, and the damping value of the sensor head of Roche coil is analyzed and designed. The testing method and flow chart of electronic transformer in the field are given. Finally, the connection mode and constraint conditions of electronic transformer used in engineering practice are studied. Finally, the use of current transformer in a 500kV intelligent substation is studied. This paper explains the selection and configuration principle of electronic transformer in the construction of intelligent substation, and explains the configuration process of electronic transformer and merging unit from each voltage level of intelligent substation. The influence of electronic transformer on relay protection is analyzed on the basis of engineering configuration.
