【摘要】：随着我国经济的迅猛发展,电力设施的各项建设工作也在不断推进。作为国家的重要产业-电力企业,一直在实现经济和社会收益最大化。而当前,我国电力行业引入的工程造价管理模式,已经无法实现电力企业成本收益最大化的目标。全寿命周期成本(Life Cycle Cost,LCC)管理是基于工程项目生命周期这一对象,通过对项目决策、设计、建设、运行维护等工程各阶段的成本控制,是一种实现全寿命周期成本最小的目标管理办法。其主要有三大特点:全费用、全系统、全过程。本文先是通过对全寿命周期成本管理理念和变电工程决策方法的历史进行分析,同时也阐述了国内外的研究情况,以全寿命周期为视角,就我国的变电工程投资决策,存在问题以及成因进行了相应的分析。提出将全寿命周期成本管理等一系列理念应用于变电工程投资决策各阶段中的管理要点和基于全寿命周期成本管理理念的相关决策方法,从而优化原有变电工程的投资决策工作。本文主要是提出了基于全寿命周期成本理论的主变压器选择和变电设备检修策略选择的应用方法。基于全寿命周期成本理论的主变压器优化方法则是基于分析主变压器回收成本的经济负载率后,提出了主变压器容量和台数选择流程,该流程就主变压器容量和台数的选择方向又重新进行了规划,简化了全阶段的各项工作。本文的内容对于分析全寿命周期成本在变电工程中的应用有一定的借鉴作用。
[Abstract]:With the rapid development of economy in our country, the construction of electric power facilities is advancing continuously. As an important industry of the country, electric power enterprises have been realizing the maximization of economic and social income. At present, the project cost management model introduced in China's electric power industry can not realize the goal of maximizing the cost and income of electric power enterprises. The whole life cycle cost (Life Cycle Cost,LCC) management is based on the object of project life cycle, through the cost control of project decision, design, construction, operation and maintenance, etc. It is a kind of goal management method that realizes the life cycle cost minimization. It has three main characteristics: full cost, whole system, whole process. This paper firstly analyzes the concept of life-cycle cost management and the history of the decision-making method of power transformation engineering, and at the same time expounds the research situation at home and abroad, taking the whole life cycle as the angle of view, the investment decision of the transformation project in our country. The existing problems and the causes are analyzed. A series of concepts, such as life-cycle cost management, are put forward to apply to the main points of management in each stage of investment decision of substation project and the relevant decision methods based on the concept of life-cycle cost management. In order to optimize the original substation project investment decision-making work. In this paper, an application method of selecting main transformer and maintenance strategy of transformer based on life cycle cost theory is put forward. The optimization method of main transformer based on the life-cycle cost theory is based on the analysis of the economic load rate of the recovery cost of the main transformer, and the selection process of the capacity and the number of the main transformer is put forward. The selection direction of the main transformer capacity and the number of stations is reprogrammed to simplify the whole phase of the work. The content of this paper can be used for reference in analyzing the application of life cycle cost in substation engineering.
