200MW汽轮机真空对功率影响特性的试验研究

Experimental Research of the Effect of 200 MW Steam Turbine Vacuum on Its Power Output

通过对国产 2 0 0MW汽轮机进行的真空变化试验确定了汽轮机的极限真空和真空变化通用曲线 ,借助于试验得到的真空修正曲线能较准确地反映机组的实际特性 。

Through a series of tests on the variation of vacuum values in a Chinese made 200 MW steam turbine determined were the turbine vacuum limit values and the general characteristic curves of vacuum variation. With the help of the vacuum correction curves obtained through tests it is possible to reflect in a fairly accurate way the actual performance of the turbine unit. This can serve as a helpful guide for assessing the performance of other similar turbine units.
