Abstract

The present invention is applicable to the technical field of distribution network, and provides a method for tuning an arc-suppression coil of a distribution network, a terminal device and a system. The method includes: acquiring a neutral point voltage of a distribution network; At the first preset threshold, determine the capacitive current of the distribution network; determine the target coil turns of the arc suppression coil according to the neutral point voltage and the capacitive current, and adjust the arc suppression coil to the Target coil turns. The invention can improve the tuning precision.

Description

technical field [0001] The invention belongs to the technical field of distribution network, and in particular relates to a method for tuning an arc-suppression coil of a distribution network, terminal equipment and a system. Background technique [0002] The distribution network is an important link in the power generation, transformation, transmission, and distribution of power systems. It is a bridge connecting the transmission system and power users, and is directly related to the requirements of users in terms of power safety, quality, and economy. However, with the development of the power grid and the increase and lengthening of cables in the distribution network, when a single-phase ground fault occurs, the capacitive current increases, and the resulting arc overvoltage problem is also becoming more and more serious, which directly threatens the safety and reliability of the power system. run. At present, the neutral point is usually grounded through the arc-suppres...
