要約(日本語): This research aims at a fast restoration scheme from outage caused by accidents on distribution lines. Tentative restoration state in aspect of security of power system is focused on. In order to achieve fast restoration from outage, precise voltage control method is necessary which can manage non-linear characteristic caused by line impedance and wide range of voltage transition. Based on newton-raphson power flow method, PQV surface is introduced to develop three voltage control method for a) starting source, b) following source and c) voltage adjusting source. Numerical calculations are conducted to verify these control methods.
