摘　　要：基于加热法湿度测量原理,推导了以易测参数为自变量的饱和蒸汽湿度在线监测模型,设计了一种适合电厂汽轮机排汽湿度在线监测的智能化装置,利用计算机的高效处理能力实现了数据采集、功率控制、在线计算和数据实时输出功能。实际运行试验证明了方法的有效性。Based on the wetness fraction monitoring principle of heating method, the on-line measuring model of saturation steam in which the independent variables are easy available are given. A new instrument is developed which can be used to measure the wetness fraction of power plant turbine. By means of the computer, the functions of data acquisition, power controlling, on-line computation and real-time data output are realized automatically. The industrial experiments have proved the validity of the method.
