The effects of factors like air-cooling fan's frequency
unit load and ambient temperature on dynamic characteristics of the direct air-cooling system in a 600MW unit was experimentally studied.The results showed that
the lower the air-cooling fan's frequency
the higher the variation speed of turbine back pressure against the ambient temperature;with a constant air-cooling fan's frequency
the variation rate of turbine pressure against the unit load increased/decreased with the ambient temperature;at a constant ambient temperature
the variation rate of turbine back pressure against the unit load showed an opposite change trend with the air-cooling fan's frequency; when the unit load was kept constant
the lower ambient temperature
the less effect of air-cooling fan's frequency on the turbine back pressure.
