If the actual field current value is reduced below the thermal limitation setpoint, the square of the difference between the actual value and thermal limitation setpoint will be integrated with the cooling time constant K.
如果励磁电流实际值降至热限制给定值以下,则利用冷却时间常数K对实际值与热限制给定值之差的平方求积分

对积分一无所知,只求表述无误,红色部分这样表达是否会让方家?谢指点!

实际值与热限给定值之差的平方将与冷却时间常数K归并。

归并??

我觉得,这里也不是求积分。与常数K怎么积分?利用常数K,更说不通。不明白这里的物理意义,最好请内行看一看。

因为该文其它地方提到过几次积分,所以这里先想到积分
