【摘要】：作为关系首都北京政治稳定、能源安全和经济命脉的国有重要骨干企业,国网北京市电力公司对于优化电网网架结构、提升供电能力、建设清洁能源配套设施等方面的投入也在持续增加,输变电工程是最重要的投资方向。而进度控制及优化则是输变电工程项目管理的重点,也是影响输变电工程项目成败的主要因素之一。国网北京市电力公司的部分属地供电公司对输变电工程项目的进度管理水平亟待提高。110kV檀营输变电工程由国网北京密云供电公司组织实施,是密云电网2015年的重要核心工程,项目的进度管理存在问题。而在输变电工程项目进度管理之中,引入了关键链技术来对整个项目的进度进行控制优化,能够在一定程度上解决目前输变电工程项目进度管理中存在的一些问题,比如说安全时间丢失、资源消耗过多等等。本文采用文献资料法、案例分析法、归纳分析法等研究方法,在对工程项目进度管理相关理论进行阐述的基础上,结合输变电工程项目进度管理的实际情况,对输变电工程项目的特点及其进度控制的主要方法进行了梳理。同时本文以110kV檀营输变电工程项目为案例,对输变电工程项目进度管理的现状以及存在的主要问题、问题产生的原因进行了分析。并以关键链理论为基础,提出了110kV檀营输变电工程项目进度控制以及优化的思路,制定了优化方案。本文的主要创新点是在梳理工程项目的逻辑关系的基础上,通过关键链技术的引进来进行进度控制优化,提出进度控制以及优化的具体措施,提出较为可行的输变电工程项目进度管理方法,最终通过项目进度的优化来提高整个项目的管理绩效。
[Abstract]:As an important key state-owned enterprise that has a bearing on the political stability, energy security and economic lifeline of the capital, the Beijing Electric Power Company of China Power Network has optimized the grid structure and enhanced the power supply capacity. Construction of clean energy facilities and other aspects of investment is also increasing, transmission and transformation projects are the most important investment direction. Schedule control and optimization is the focus of power transmission and transformation project management, and it is also one of the main factors that affect the success or failure of power transmission and transformation projects. The progress management level of some dependent power supply companies of Beijing Electric Power Company needs to be improved urgently. 110 kV Honolan Power Transmission and Transformation Project is organized and implemented by Beijing Miyun Power supply Company of State Power Network, which is an important core project of Miyun Power Grid in 2015. There are problems in the progress management of the project. In the project schedule management of power transmission and transformation projects, the critical chain technology is introduced to control and optimize the whole project schedule, which can solve some problems existing in the current project schedule management of power transmission and transformation projects to a certain extent. For example, loss of security time, excessive consumption of resources and so on. This paper adopts the methods of literature, case analysis, inductive analysis and so on, on the basis of expounding the related theories of project schedule management, and combining with the actual situation of project schedule management of power transmission and transformation projects, The characteristics of power transmission and transformation projects and the main methods of schedule control are combed. At the same time, this paper takes the 110kV Honolan power transmission and transformation project as an example, analyzes the present situation of the progress management of the power transmission and transformation project, the existing main problems, and the causes of the problems. On the basis of critical chain theory, the idea of schedule control and optimization of 110kV Honolan power transmission and transformer project is put forward, and the optimization scheme is worked out. The main innovation of this paper is that on the basis of combing the logical relationship of the engineering project, through the introduction of critical chain technology, the progress control optimization is carried out, and the concrete measures of progress control and optimization are put forward. This paper puts forward a feasible project schedule management method of power transmission and transformation project, and finally improves the management performance of the whole project by optimizing the project schedule.
