This paper constructs the affection model of temperature difference of heaters of 300 MW units on cycle efficiency based on the equivalent heat drop method and the q-γ-τmatrix. It is proposed that affection on the cycle efficiency is different depending on the different heater' s position in thermal systems. It is not suitable to select same value for all heaters, or select the same values in both high pressure and low pressure heaters.
