Taking the most representative 600~699 MW level air-cooling generator set in China as the example
the Ebsilon software was applied to establish the cogeneration system model for the centralized high back pressure air cooling unit
and the change rule of proportion of generating capacity with the high back pressure heat load under different working conditions was analyzed. The variation of the unit's overall income with the ratio of electric heat to heat price is obtained. The results show that
when the external heat load is constant
the actual maximum power generation can be obtained by adjusting the proportion of high back pressure heat load and the specific value is obtained by an example
and it is smaller than the ideal maximum power generation. When the external heat load and ratio of electric heat to heat price changes
this paper determines which operating strategy can be used to maximize the unit's overall revenue. The research results provide a reference operational strategy for air-cooled cogeneration units.
