Abstract

Abstract: With the continuous development and promotion of new energy technology, the traditional distribution network structure has been changed. After the new energy power is connected, the distribution network has changed from a traditional single-ended power supply radiation network to a dual-end or multi-end power supply network. Some active arc suppression methods often ignore the impact of new energy power supply when calculating the injected current. Aiming at the above problems, and drawing on the existing flexible grounding technology, this paper proposes an arc suppression method for new energy distribution networks based on active inverter split-phase injection, which comprehensively considers the impact of system-side power and new energy-side power on the injection current calculation. It is shown that this method can effectively compensate the fault current and can effectively suppress the re-combustion of AC arc.
