| Abstract |
Low Voltage DC (LVDC) distribution system has paid attention because people are trying to improve energy efficiency and reduce loss of energy. In addition, many researches related to DC system are conducted to replace the AC-based power supply due to the increase of digital load and distributed generation. However, research on standard and protection scheme is still incomplete to achieve the stable and reliable operation of LVDC distribution system. Thus this paper studies protection algorithms in the LVDC distribution system. First, this paper analyzes proper protection algorithms in LVDC distribution system by comparing with those in AC distribution system. And then, it performs the modelling of a simple LVDC distribution system and the simulation by using EMTP(ElectroMagnetic Transients Program). |
