【摘要】：华能营口电厂脱硫系统已经不能适应现代社会经济发展的需要,必然进行脱硫增容改造,以保证脱硫效率的提升和排放浓度的下降,还符合国家和地方环保政策的约束。有必要对华能营口电厂脱硫系统增容改造项目进行深入分析,结合火电厂脱硫系统增容改造项目工程建设的特点,讨论和分析如何能够合理的控制工期,如何合理的控制进度,在保质保量、安全可行、而且在不增加建设成本的前提下尽可能减少工期。首先,研究明确了华能营口脱硫系统增容改造的必要性。即保证脱硫效率的提升和排放浓度的下降,以及符合国家和地方环保政策的约束。华能营口电厂有必要进行超低排放改造,达到大气污染物“超低排放”限值,二氧化硫、烟尘和氮氧化合物的排放要符合一定的标准。其次,华能营口脱硫系统增容改造项目进度管理存在的问题及成因进行深入分析。通过对项目整体分析,得出前期准备不充分,设计不周全,图纸拖期的问题,以及内部协调机制不健全,沟通难以顺畅表达。此外,对安全管理不到位和劳动力不足问题也进行了详细阐述。对准备不充分、沟通不顺畅、安全不到位和劳动力不足四个问题的原因进行总结,对制约项目顺利进行的影响因素进行梳理。再次,研究华能营口脱硫系统增容改造项目进度的优化和控制方案。在进度计划的调整优化方面,提出进度控制优化方法、前期进度计划、施工进度计划和验收进度计划四个方面分别说明,采用计划分解结构图、甘特图、网络图和关键路径图四种方式对优化方法进行说明。在项目控制方法上总结了事前控制、事中控制和事后控制的关系,研究采用事前控制和事中控制相结合的方式,事后控制进行补充,充分说明了项目改造的进度控制方法。最后,提出华能营口脱硫系统增容改造项目进度的保障措施。研究从解决资源浪费的保障、制度管理的保障和安全保障三个方面充分说明项目保障管理的重要性。在资源浪费方面,提出资源配置、降低成本和消除设计缺陷三个方面具体的保障措施。在制度保障方面,提出组织措施、技术保障、信息保障、进度保障四个方面的保障措施。在安全保障方面,提出安全管制措施、雨季施工措施、防雨防电保障、防火防爆安全保障四个方面。本文以项目管理理论为基础,结合火电厂脱硫系统增容改造项目工程建设的特点,讨论和分析如何能够合理的控制工期,因超低排放改造项目具有投资大、工程量大和工期长等特点,这对于主体工程为脱硫系统增容改造项目的电厂来说都是一项较大的投资。如何合理的控制进度,在保质保量、安全可行、而且在不增加建设成本的前提下尽可能减少工期就成为当下大多数电厂努力研究的问题。这项研究成果不仅仅可以应用于营口电厂脱硫系统增容改造项目,还可以在其他电厂以及其他大型更改项目中进行推广。
[Abstract]:The desulfurization system of Huaneng Yingkou Power Plant can not meet the needs of modern social and economic development, so it is necessary to carry out desulphurization and capacity enhancement to ensure the improvement of desulphurization efficiency and the decrease of emission concentration. It is also in line with the constraints of national and local environmental protection policies. It is necessary to carry out in-depth analysis of the capacity increase and transformation project of Huaneng Yingkou Power Plant desulfurization system, combining with the characteristics of the project construction of the capacity increase and transformation project of the desulfurization system of thermal power plant. Discuss and analyze how to control the construction period reasonably, how to control the schedule reasonably, which can reduce the construction period as far as possible without increasing the cost of construction. First of all, it is safe and feasible to ensure the quality and quantity of the project. The necessity of capacity increase and transformation of Huaneng Yingkou desulfurization system is studied, that is, to ensure the improvement of desulphurization efficiency and the decrease of emission concentration. And in line with national and local environmental protection policy constraints. Huaneng Yingkou power plant is necessary to carry out ultra-low emissions transformation, to achieve the atmospheric pollutants "ultra-low emissions" limit, sulfur dioxide. Emissions of soot and nitrogen oxides should meet certain standards. Secondly, the problems and causes of schedule management of Huaneng Yingkou desulphurization system capacity increase project are analyzed. Through the overall analysis of the project. Draw early preparation is not enough, design is not perfect, drawing delays, as well as internal coordination mechanism is not perfect, communication is difficult to express smoothly. The problems of inadequate safety management and labor shortage are also discussed in detail. The reasons for the four problems are summarized, such as inadequate preparation, poor communication, inadequate security and insufficient labor force. Thirdly, research on the Huaneng Yingkou desulphurization system capacity increase project schedule optimization and control program. In terms of schedule adjustment and optimization. Proposed the schedule control optimization method, the Prophase schedule plan, the construction schedule plan and the acceptance schedule plan four aspects respectively explains, uses the plan to decompose the structure chart, the Gantt chart. Network diagram and critical path diagram are four ways to explain the optimization method. In the project control method, the relationship among the prior control, the control in the event and the control after the event is summarized. The research adopts the combination of pre-control and in-the-event control, and then complements it with after-control, which fully explains the progress control method of the project transformation. Finally. This paper puts forward the measures to guarantee the progress of the capacity increase and renovation project of Huaneng Yingkou desulphurization system, and studies the guarantee of solving the waste of resources. The guarantee and security of system management fully explain the importance of project security management. In the aspect of waste of resources, resource allocation is put forward. In the aspect of system guarantee, the paper puts forward four safeguard measures: organization measure, technical guarantee, information guarantee, schedule guarantee. In the aspect of security, the author puts forward the following three aspects: reducing cost and eliminating design defects, and puts forward four kinds of safeguard measures: organization measure, technology guarantee, information guarantee and progress guarantee. Safety control measures, construction measures in rainy season, rain and electricity protection, fire and explosion protection are put forward. This paper is based on project management theory. Combined with the characteristics of the project construction of the desulfurization system of thermal power plant, this paper discusses and analyzes how to control the construction period reasonably, because the super-low emission reconstruction project has the characteristics of large investment, large amount of construction and long construction period, and so on. This is a large investment for the power plant of the main project for the capacity increase of desulphurization system. How to control the progress reasonably, in quality and quantity, safety and feasibility. And without increasing the construction cost, reducing the construction period as much as possible has become the problem of most power plants. This research result can not only be used in Yingkou power plant desulphurization system capacity increase transformation project. It can also be popularized in other power plants and other large-scale change projects.
