燃气轮机相对内效率 adiabatic turbine efficiency
If they work at the original designed mode, when the load of electric grid is low, the throttling loss of the governing valve in steam turbine will increase, and the relative internal efficiency of steam turbine will decrease.
如果机组按照出厂设计的阀门开启方式,那么在低负荷时机组的调节汽门节流损失将增大,汽轮机相对内效率降低。
