快速安全提高汽轮发电机转子检修质量。。。摘要：针对用户对负载供电不间断的实际需求，分析了数码发电机的内部结构及其不能实现供电的不间断性能的原因，提出一种由数码发电机改造组成的交流不间断供电系统的设计方法。该设计利用发电机内部的逆变器，在市电正常时，由市电经过逆变器给负载供电，同时给蓄电池充电；在市电断电时，一边启动发电机，一边由蓄电池的直流电通过逆变器转换成交流电供负载使用，实现无论市电正常还是异常，系统对负载提供不间断电源。设计对市电进行稳压、稳频、输出零切换、蓄电池的充放电管理等新功能。此设计无需单独购买不间断电源，避免重复投资和资源浪费。

The multi-dimensional signals measured by sensors with a machine working under normal condition or fault condition, can be used to build Q statistic and T^2 statistic respectively to detect the state of the machine.
