燃气-蒸汽联合循环自备热电联供经济敏感性分析

分析了蚌埠新城开发区拟建燃气蒸汽联合循环自备热电联供项目的内部收益率和投资回收期这两个主要经济指标,并指出了总投资、天燃气价格、电价、热价4个因素经济敏感性的起变动范围和次序.最后得出了净现值NPV与电价、天燃气价格、热价之间的多因素敏感性关系图.;The proposed project of the internal co-distribution of combined gas-heat cycling of Xin Cheng Development Zone of the City of Bangbu is analyzed in terms of the two major economic indexes, namely, its internal profitability and rate of returns on investment,indicating the economic sensitivity and its range of fluctuation and its order of variations of such four factors as total investment, natural gas price, electricity price and heat price, thus eventually coming up with a diagram showing the relation sensitivity of the net present value [NPV] vis-a-vis the price of electricity,natural gas and heat
