發(fā)布時間:2019-06-04 07:36
【摘要】:工程中部分忽視平衡繞組的做法給平衡繞組雙卷變壓器的安全運(yùn)行帶來了隱患。因此,在總結(jié)平衡繞組雙卷變壓器參數(shù)錄入的基礎(chǔ)上,分析平衡繞組對正序、零序回路的影響,研究了平衡繞組對變壓器抗短路能力及繼電保護(hù)的影響。修正并完善了與平衡繞組雙卷變壓器相關(guān)的繼電保護(hù)整定計算原則,從繼電保護(hù)角度保證了平衡繞組雙卷變壓器及電網(wǎng)的穩(wěn)定運(yùn)行。
[Abstract]:The partial neglect of balanced winding in the project brings hidden trouble to the safe operation of balanced winding double-coil transformer. Therefore, on the basis of summing up the parameter input of balance winding double coil transformer, the influence of balance winding on positive sequence and zero sequence loop is analyzed, and the influence of balance winding on short circuit resistance and relay protection of transformer is studied. The setting calculation principle of relay protection related to balanced winding double-coil transformer is modified and perfected, and the stable operation of balanced winding double-coil transformer and power grid is guaranteed from the point of view of relay protection.
