On the 12kw , 4 - pole salient pole synchronous machine , three phase symmetrical short circuit experiments and kinds of typical internal faults experiments are carried out in case of single machine with no - load and with resistance load at terminal . based on the above two mathematical model , simulations are also made under the same conditions 本文對(duì)一臺(tái)4極、 12kw凸極同步發(fā)電機(jī),在單機(jī)空載和機(jī)端帶電阻負(fù)載的運(yùn)行狀態(tài)下,進(jìn)行了機(jī)端外部短路和多種典型內(nèi)部故障的實(shí)驗(yàn),并用兩種數(shù)學(xué)模型做了相應(yīng)的仿真計(jì)算。
