摘要
针对现有G60保护中的发电机对称过负荷反时限保护,存在的定子对称过负荷反时限保护特性曲线与发电机厂提供的发电机定子绕组允许过负荷能力无法有效配合问题,提出了一种有效的逻辑优化解决方案,实施改造后,取得了良好的效果。
According to generator symmetric overload inverse time protection in the existing G60 protection,the existing problem is that the stator symmetry overload inverse time protection characteristic curve can not effectively cope with the overload capacity allowed by generator factory for generator stator winding. A kind of logic optimization solution was put forward. After implementation of improvement, good result has been obtained.
