励磁输入和效率励磁输入和效率事实上，HS y额定负载运行时励磁损耗相当大，与PMSY相比效率下降。
The fact is that when HSY is operated at rated load, magnetic loss is rather high, and efficiency drops compared to PMSY.
运行状态包括额定负荷、负荷调节后的稳态及励磁调节后的稳态。
The operating conditions are those steady state conditions, such as the one with rated load, the one after load regulation and the one after field regulation.
