【摘要】 通过3台发电机主保护定量化设计结果的对比,说明在大中型发电机定子绕组的初步设计中应考虑发电机中性点侧的引出方式、实际可能发生的内部故障特点和相应的主保护配置方案。发电机设计(一次)与继电保护(二次)工作的分离,存在发电机安全运行的隐患。只有发电机设计与继电保护密切合作,才有可能完成定子绕组的优化设计。更多还原

【Abstract】 Through the comparison of main protection quantification design for 3 generators, it was explained that the way of outlet for generator neutral point, the internal fault characteristics and corresponding disposition scheme of main protection should be considered during the primary design of large and medium-sized generator stator winding. The separation of generator design (primary) and protection (secondary) can produce the hidden trouble in safe operation of generator. The close cooperation between generator design and protection can only be a way to do optimization design for generator stator winding.更多还原
