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 本文對一臺4極、 12kw凸極同步發(fā)電機,在單機空載和機端帶電阻負載的運行狀態(tài)下,進行了機端外部短路和多種典型內(nèi)部故障的實驗,并用兩種數(shù)學模型做了相應(yīng)的仿真計算。
