摘要
小信号运算电感数值计算中的问题有:增量磁导率的使用,转子绕组的处理等。本文采用场路耦合法处理转子的阻尼绕组和励磁绕组,既合理地反映了转子的复杂回路,又避免了端部漏磁引起的修正。通过对采用不同磁导率计算的比较,得到了一些具有实际意义的结果。
In order to solve the problem of non-sinusoidal voltage supplying salient-
pole synchronous machines raised by barmonics, it is necessary to calculate
small signal operational inductances of salient-pole synchronous machines
exactly. The problems on calculation of small signal operational induc-
tances are: the application of incremental permeabilities, the treatment of
rotor windings. By using the method of coupled field and circuit to deal
with damper windings and field winding in rotor, complicated rotor circuits
can be treated properly and the additional modification to results due to end
leakage flux can be avoided. Besides, some practical conclusions are obtain-
ed in the calculation analysis by different permeabilities.
