摘要：
The applied single-phase reclosing scheme for wind power outgoing line with shunt reactors simply uses single-phase reclosing scheme for conventional power transmission line, which recloses without identifying fault characteristics, and the relevant wind farm and power system will suffer from secondary strike. Moreover, considering shifting wind power outgoing line working condition, the existing transmission line single-phase reclosing scheme can hardly be applied on wind power outgoing line. By analyzing characteristics of faulty phase active and reactive power ratio before and after fault, an adaptive single-phase reclosing scheme based on power ratio for wind power outgoing line with shunt reactors is proposed. Theoretical analysis and simulation experiments verify that, the proposed reclosing scheme can adapt the shifting working conditions of wind power outgoing line, identify fault characteristics and the arc extinction time quickly and accurately, and immune to the variation of fault distance and transition resistance. © 2018 Automation of Electric Power Systems Press.
