| Abstract: | According to the features of many multilevel short line branches, round-type power supply lines and T-type connections in distribution network, the principle of a new network-based adaptive current protection is proposed. Using the combination of communication technology with adaptive setting of current protection, the selectivity of tripping can be ensured and the problem which is difficult to be solve, i.e., the selectivity and the protection region of traditional three-step current protection are influenced by failure modes in distribution network, is solved. |
