Abstract

Aiming at overcoming the deficiency of the current compensation modes in MV power networks, this article proposes a new compensation mode that is a mode of the combination of presetting mode and following-setting mode. In this compensation mode, the Petersen coil is preset to some place that is about 15% over compensation when the network is on the normal state, and the Petersen coil is quickly following-set to the full compensation point when some single-phase-to-ground fault occurs. This article then analyses the principle of the arc-suppression. This compensation mode is already tested on the 10 kV high voltage physical simulation system, which testifies the validity and reliability of this mode. This compensation mode can make the best of the Petersen coil and improve the arc-suppression ability of the Petersen coil. It can also make the fault-line selection more easily, and then it can enhance the security and reliability of the power networks.
