摘要
本文介绍以概率理论为基础的称为综合似然率试验的传感器故障在线自动检测技术，它不仅能检测传感器的故障，而且能诊断出故障的类型、幅值及发生的时间，保证了电站的控制和专家系统的正常工作，从而可提高电站的使用率，优化其性能及提高机组的寿命。
In the paper, the sensor on line failure detection technique called Generalized Likelihood Ratio (GLR) test is introduced. It can not only detect the failure of a sensor, but also estimate the type, magnitude and time of the failure, so that the control system and the expert system of the power plant can operate normally, furthermore, the utility factor can be raised, the performance be improved and the lifetime be prolonged..
