Evaluation of Existing DC Protection Solutions on an Active LVDC Distribution Network under Different Fault Conditions

چکیده
Low Voltage Direct Current (LVDC) distribution is considered as one of the new promising technologies for better integration of distributed generation, and supplying local loads in more efficient way compare to AC systems. However, DC protection is still considered as one of the outstanding challenges that holds back the wide deployment of LVDC in last mile utility applications. Most of existing DC solutions have been developed for specific applications such as data centres, PV systems, electric ships, and traction systems. However, their suitability for providing a good level of protection and safety for an LVDC last mile public network is still not fully understood. Therefore, this paper evaluates the performances of a wide number of DC protection solutions that have been proposed for the applications on an active LVDC last mile distribution network with local generation sources (including PVs and battery storages). Based on the findings, recommendations of LVDC protection for resilient operation are presented in the paper.

متن کاملDevelopment of Fault Detector for Series Arc Fault in Low Voltage DC Distribution System using Wavelet Singular Value Decomposition and State Diagram
It is well known that series arc faults in Low Voltage DC (LVDC) distribution system occur at unintended points of discontinuity within an electrical circuit. These faults can make circuit breakers not respond timely due to low fault current. It, therefore, is needed to detect the series fault for protecting circuits from electrical fires. This paper proposes a novel scheme to detect the series...

The unbalance currents injection by power electronic transformers in order to improve the unbalance voltage conditions of the network causes an imbalanced voltage in the DC link capacitors and creates an active powers inequality in the different phases. In this paper, the proposed control structure independently controls the active power of each phase by modifying the power angle between the vo...
