摘　　要：通过对外部性内部化理论的分析,提出了应用动态盈亏平衡分析模型确定脱硝电价的方法,确定SCR工艺作为参照性脱硝技术,以某发电有限公司新建2×600MW机组烟气脱硝工程为例,对模型进行了验证,分别计算了电价收入、影子收入、脱硝可变成本、年固定经营成本、年固定资产投资、回收资产残值,并以此为基础编制了现金流量表,计算出脱硝电价。最后通过敏感性分析筛选出影响脱销电价的主要因素,并据此对脱硝电价相关配套政策提出了建议。The method using dynamic breakeven analysis model to determine the denitration price is proposed in this paper according to the analysis of the externalities internalization theory. The SCR process is selected as a standard of denitrification technology, and a new 2 × 600 MW units flue gas denitration project in a power generation company is taken as the case to validate the model. Then the tariff income, the shadow income, the annual variable cost, the annual fixed run costs, the annual capital investment and the recovery of assets residual value are calculated to make the cash flow statement and to calculate the denitration price. Finally, the main factors which affect the denitration price are screened by sensitivity analysis and the policy suggestion is made.
