介绍了水轮发电机定子及转子表层过负荷保护的原理,通过比较南瑞继保的RCS-985保护装置与国电南自的DGT801保护装置在发电机定子绕组过负荷反时限和转子表层过负荷反时限保护整定计算中的差异,避免因定值计算错误造成保护误动或拒动。
The principle of overload protection of hydrogenerator stator and rotor surface is introduced. By comparing the anti-overload of rotor winding of generator with RCS-985 protection device of NARI protection and DGT801 protection device of SINOMACH self-assembly, The inverse time protects the difference in setting calculation to avoid the misoperation or refusal of protection caused by the incorrect calculation of fixed value.
