The effect on the generator excitation magnetic field is different when the capacity and power factor of load are different, and the effect on the internal impedance voltage drop is different, too.
The paper depicts the magnetic energy calculation for no load of hydrogenerator de excitation energy capacity calculation with linear and non linear resistor.
本文分析了空载水轮发电机磁场能量计算和空载误强励下,用线性电阻或非线性电阻灭磁时灭磁能容的计算。

Along with the synchronization power set capacity increasing, for prevent the generator interior breakdown from expanding, the generator has a higher request to the de-excitation system.
