Abstract

There are many devices in the smart distribution network, and the current differential protection methods are stronger for fiber optic or Ethernet communication, which cannot solve the problem of low protection efficiency caused by the protection data transmission delay. To solve the problems analyzed above, the adaptive differential protection method for smart distribution network under the framework of 5G communication is studied. After establishing the 5G communication framework for differential protection data synchronization in smart distribution networks, the protection data synchronization is realized by using the self-synchronization algorithm. The adaptive differential protection is achieved by adding braking coefficients to the conventional differential protection scheme and introducing new adequate protection criteria. In the simulation experiment, the protection efficiency of the protection method using 5G is improved by nearly 45.4%, and the effective protection rate is significantly increased.
