【摘要】：近年来,由于电力需求的迅速增加,现存变电站逐渐难以满足电网技术的发展和电网安全运行的需求,变电站改造对电网建设作用日益重要。与新建电站不同,变电站改造工程具有工程施工量大、施工方法多变、施工面较多和施工人员交叉作业等特点。目前,110kV及以下变电站在我国面临许多改造或扩建工作。同时,我国电力工程改造缺乏经济性和高效率的项目管理体系。因此,采用现代项目管理方法研究110kV及以下变电站改造项目的质量管理和进度管理具有重要意义。本文结合江门110kV桥头变电站改造项目中建筑工程、设备安装、调试工程以及物资供应与工程质量与进度等环节的实际情况,首先介绍项目质量管理与进度管理的基本理论；其次,对变电站改造工程的属性进行一般性的界定,以区别变电站新建工程。基于此,针对变电站改造工程提出质量管理和进度管理方法,并阐述改造工程进度和质量之间的辩证依存与交互影响以及控制与协调的相应方法。在概述江门110kV桥头变电站改造工程的基础上,结合“5S”管理方法,设计质量管理体系(QMS)的持续改进模式,同时,介绍改造项目的总体流程,运用工作结构分解法(WBS)对改造工程进行分解,运用网络计划技术(CMP)估算和分析工程项目关键工序的持续时间,并运用净得值分析法对项目的进度控制进行分析。结合上述分析,找出项目质量与进度的影响因素,依次建立指标体系,并用模糊综合评价方法对改造工程质量进度综合等级进行评价。最后,基于项目的质量和进度管理分析以及综合评价结果,针对工程项目管理中存在的问题,提出对应的解决措施,从而为我国其他变电站施工工程质量与进度的管理提供可借鉴的经验。
[Abstract]:In recent years, due to the rapid increase of power demand, the existing substation is gradually difficult to meet the needs of the development of power grid technology and the safe operation of the grid. Substation transformation is increasingly important to the construction of the power network, which is different from the new power station. Substation reconstruction project has the characteristics of large amount of construction, variable construction methods, more construction surface and cross-operation of construction personnel, etc. At present. 110kV and below substations are faced with a lot of renovation or extension work in our country. At the same time, the transformation of electric power engineering in our country is lack of economical and high efficiency project management system. It is of great significance to adopt modern project management method to study the quality management and schedule management of 110 kV and below substation transformation projects. This paper combines the actual situation of the construction project, equipment installation, commissioning project, material supply, quality and progress of the project in Jiangmen 110kV Qiaotou substation transformation project. Firstly, the basic theory of project quality management and schedule management is introduced. Secondly, the attributes of substation transformation project are generally defined to distinguish the new substation project. Based on this, the quality management and schedule management methods are put forward for substation transformation project. The dialectical dependence and interaction between the progress and quality of the revamping project and the corresponding methods of control and coordination are described. The reconstruction project of Jiangmen 110kV Qiaotou substation is summarized. Combined with the "5S" management method, the continuous improvement mode of QMS is designed. At the same time, the overall process of the reconstruction project is introduced. The method of work structure decomposition (WBS) is used to decompose the reconstruction project and the network planning technique is used to estimate and analyze the duration of the key processes of the project. And the use of net value analysis of the project progress control analysis. Combined with the above analysis to find out the quality and progress of the project factors, and set up an index system in turn. Finally, based on the project quality and schedule management analysis and comprehensive evaluation results, in view of the existing problems in engineering project management. The corresponding solutions are put forward so as to provide reference experience for the management of construction quality and schedule of other substations in China.
