Fault Current Limiting (FCL), applied in fault current condition, is a strategy to reduce network voltage disturbances. The objective of this research is to investigate different FCL approaches for Dynamic Voltage Conditioner (DVC) system within an example LV radial network, the proposed approach could also be adopted for other electronic devices, as Dynamic Voltage Restorer (DVR).

Abstract

Fault Current Limiting (FCL), applied in fault current condition, is a strategy to reduce network voltage disturbances. The objective of this research is to investigate different FCL approaches for Dynamic Voltage Conditioner (DVC) system within an example LV radial network, the proposed approach could also be adopted for other electronic devices, as Dynamic Voltage Restorer (DVR). Here, a single-phase DVC has been considered because it is an interesting PQ conditioner for Distribution System Operator (DSO). In this paper, a comparison of performances between different approaches will be considered taking into account: the stress on DVC equipment, that needs to be analyzed in order to protect power electronic components and DC link capacitor bank. Also, in order to guarantee proper and in time opening of upstream circuit breaker, the fault current is analyzed that can be limited but only to a certain amount.
