摘要:
 摘要:大型汽轮发电机带负荷失磁分析中,首先建立大型汽轮发电机从失磁到失磁后有功功率调

分析,证明该大型汽轮发电机从失磁到有功功率调节过程的仿真模型的正确性,最后对QFQS -
200 - 2汽轮发电机带不同比例有功功率负荷发生失磁故障进行分析,分析了该电机失磁后定子电
流、定子电压、转子的转速、输出的有功、无功的变化,以及失磁后立刻减少所带有功功率负荷后上
述各输出量的变化,为大型汽轮发电机带额定负荷发生失磁故障,提供有功功率调节量值。
Abstract:
 Abstract:In analysis of large steam turbine generator model with load loss of excitation,simulaion model
of the large steam turbine generator from excitaion loss to the active power regulation was set up,and for
QFQS一200一2,regulating process from excitation loss to active power were simulated and experimental
comparison was conducted. It shows the correctness of the simulation model in the active power regulation
process,and excitation loss faults were analyzed which are caused by the QFQS一200一2 turbine genera-
for with different proportion of active power load. The stator current,stator voltage,rotor speed,the
change of the output of the active and reactive power, and variation of all output immediately after loss of
excitation reduction with active power load were analyzed. The results and analysis provide regulated val-
ues of active power when large steam turbine generators with rated load generate faults of excitation loss.
