3.7 CALCULATION OF ANNUAL POWER GENERATION 201

3.7.3 Thermal Power Plant Capacity Optimization
Thermal power plant system calculation in the previous section
has been based on the fact that the capacity of a steam turbine has
been specified in advance. Furthermore, an alternative calculation
method is that as the generating capacity is the core index to
determine the price, it is possible to firstly assume an initial invest-
ment and expected price, then the corresponding annual generating
capacity can be inversely deduced based on these two factors. As
the annual generating capacity is relevant to the system efficiency,
after determining the generating capacity, it is also possible to
calculate the annual generating efficiency based on local meteoro-
logical conditions.
In case of the power price of the power plant being considered as a
modifiable quantity, technical and economic optimization for the power
plant can also be conducted according to the method shown in Fig. 3.47,
and a reasonable power price can be obtained.
