The application discloses a kind of based on multi-
specialty bill of quantities building SOFC power supply
system economy evaluation method, it is related to distributed
energy system economy evaluation technical field;The method takes the process, electrical,
civil engineering,
instrument control multi-
specialty bill of quantities of building SOFC power supply project as core input, realizes evaluation by "
list parameter analysis→dynamic investment
estimation→multivariate
financial evaluation→profit boundary determination" four general processes: first, the mapping rule of
list and evaluation index is established, and the core parameters are extracted;Then, combined with regional quota and market benchmark price, a dynamic model is constructed to calculate the
total investment;Introduce product maturity and operation parameter variable, calculate annual profit through general formula;Finally, the break-even point is determined by single-factor
sensitivity analysis to determine the profit potential of the project.
