变电站建筑工程造价风险分析

Risk Analysis of Substation Construction Cost

当前的输变电工程造价主要可以分为三大类:输电线路造价、变电站安装造价、变电站建筑造价。其中,输电线路工程造价高,但项目相对较少,计算难度小,工程造价的难点在于通道协调费用的确定;变电站安装工程技术含量高,项目多,但是项目相对固定,只要设备选型不变,工程造价不会出现太大变化,其难点在于二次设备及电缆工程量的确认;变电站建筑工程的特点是项目繁多、精细,工程造价的难点在于涉及面较广且可变因素较多。变电站建筑工程虽然在整体输变电工程中不是造价最高的,却是管控难度最大的。由此,本文首先分析变电站建筑工程造价现状,然后探讨变电站建筑工程造价风险,最后提出变电站建筑工程造价风险管控措施。

The current transmission and transformation project cost can be divided into three categories:transmission line cost,substation installation cost and substation construction cost.The cost of transmission line project is high,but the project is relatively few,and the calculation is difficult.The difficulty of project cost lies in the determination of channel coordination cost;Substation installation engineering has high technical content and many projects,but the projects are relatively fixed.As long as the equipment selection remains unchanged,the project cost will not change much.The difficulty lies in the confirmation of the quantities of secondary equipment and cables;Substation construction project is characterized by many and fine projects.The difficulty of project cost lies in wide range and many variable factors.Although the substation construction project is not the highest cost in the overall power trans⁃mission and transformation project,it is the most difficult to control.Therefore,this paper first analyzed the current situation of substation construction project cost,then discussed the risk of substation construction project cost,and fi⁃nally put forward the risk control measures of substation construction project cost.
