| 摘 要： | 本文提出一种新的灭磁时序,分析了多种可能工况下发电机转子灭磁的效果。仿真结果表明采用这种灭磁时序可以有效地实现交直流冗余灭磁。这种灭磁时序甚至可以将对直流灭磁开关弧压要求降低到灭磁电阻残压大小,对发电机的灭磁具有指导意义,可以广泛地应用到采用非线性电阻的发电机灭磁中去。

| Abstract: | A new de-excitation sequence is proposed in this paper. Simulation result indicated that DC and AC redundancy de-excitation could be performed effectively when the new sequence was applied. This sequence will reduce the requirement of the arc-voltage of DC field circuit breaker to the remain-voltage of nonlinear-varistor. It is helpful for the design of generator de-excitation, and can be applied widely when nonlinear-varistor is used. |
