综合交通枢纽工程是整合了各类交通为一体的协同交通体系,初期投资巨大,并且庞大的建设规模亦带来运营期较大的成本支出,因此做好全生命周期的资金平衡工作尤为重要。目前在建或已经竣工的该类工程中,建设期成本计算方法各有不同,造成... 综合交通枢纽工程是整合了各类交通为一体的协同交通体系,初期投资巨大,并且庞大的建设规模亦带来运营期较大的成本支出,因此做好全生命周期的资金平衡工作尤为重要。目前在建或已经竣工的该类工程中,建设期成本计算方法各有不同,造成同类工程成本各异的局面,不利于合理确定建设投资;现行的《市政公用设施建设项目经济评价方法与参数》中不包括综合交通枢纽工程,因此该类工程运营期收支测算工作目前也不成熟和规范。文章通过比较分析各专业工程涉及的计价体系特点以及适用范围,采用典型案例研究综合交通枢纽各项建设成本的组成和计算方法,梳理出一套该类工程投资估算(概算)编制办法;在《市政公用设施建设项目经济评价方法与参数》的基础上,根据综合交通枢纽的特点,探索出该类工程运维期成本和效益测算的计算模型、各项费用的计算参数以及计算方法,为后续综合交通枢纽工程全生命周期资金平衡测算工作提供参考。 展开更多

The first stage project of Jiuquan wind energy base with 5.5-GW installed capacity is about to be completed. However, there exist several technical issues such as power transfer capability, electricity accommodation, frequency control and peak load regulation as well as system stability. In addition, the high capital cost and operation cost of the supporting transmission project invested and constructed by the Gansu Provincial Power Company will definitely have significant impacts on the management and economic profit of the Company. Through analysis of the construction and operation cost changes resulting from the wind power collection and delivery project, the author carried out research into the effects of developing large-scale wind power base on the management and economic benefits of power grid enterprises and proposed corresponding suggestions to make the related policies perfect. 展开更多
