| Abstract: | As the first line of the "three defence lines" for the safe and stable operation of the power grid,the relay protection is of great importance.The characteristics and selection of the mutual inductor,the development of the non-conventional mutual inductor,the working principle of various relay protections,the configuration of UHV protection are analyzed,as well as the influences of time delay,data and clock synchronization,IEC61850 and communication technology development on the protection system based on the mutual inductor technology,the protection principle and the communication technology.Suggestions on application of the protection technologies are proposed. |
