| 摘 要： | 在线监测凝汽式汽轮机相对内效率时，由于排汽的湿度至今还没有一个可靠的在线测量手段，因而难以得到准确的排汽焓，从而使在线确定汽轮机相对内效率比较困难。针对这一情况，在发电厂易测参数的基础上，本文提出了一种在线监测凝汽式汽轮机相对内效率的新方法，并对该方法的计算误差进行了分析。

| Abstract: | When relative internal efficiency of condensing steam turbine is monitored on-line,it's difficult to get the exhausting steam enthalpy accurately for the reason of without a reliable on-line measuring method for the exhausting steam humidity up to now.Therefore,on-line determining relative internal efficiency is difficult relatively.Base on this condition,a new method of on-line monitoring relative internal efficiency for condensing steam turbine on the basis of easily measured parameters in power plant is proposed in this paper,and the calculating error of this method is analyzed. |
