【摘要】：随着科学技术发展,新型设备不断出现与新的设备管理理念逐步应用到实际管理工作中,积极探索新的技术方法与管理方法,降低设备在运行周期内的投资成本,提高运行设备的可靠性,最大限度使电气设备发挥其寿命周期内的效能,成为电网建设与成本管理中的一个亟待探索的问题。目前,电力企业在电网建设设计初期的设备选型过程中,只注重对设备初期投入的控制,而往往忽视了设备投入运行后各检修阶段、故障阶段等环节资金的投入,同时电力企业并未有健全的电力设备可靠性分析和与之相对应的设备成本分析,从而直接造成电器设备的资产全寿命周期成本过高,直接影响电力企业的经济效益。本文从设备可靠性分析入手,分析了目前设备可靠性分析存在的不足,进而从资产全寿命周期管理理念的视角出发,提出了基于SEC指标的全寿命周期管理在唐山电网中的应用。全寿命周期成本管理是一种全面、科学、先进的管理理念和方法,其核心是对项目全寿命周期的各个阶段进行统筹管理,在资产安全可靠运行和满足使用需求的条件下,使资产全寿命周期的整体成本最低。本文首先对设备可靠性理论进行研究,确定电力设备可靠性模型,其次,对全寿命周期成本管理中安全、效能、成本指标的模型、框架、特点、评估方法与取值原则等相关理论做了全面系统的介绍。在对电网设备周期成本管理现状分析的基础上,深入研究了全寿命周期成本管理在设备运行各阶段的具体应用流程,通过引入变压器设备实例,进行了SEC指标管理在实际设备运行中各指标值的对比分析,通过对比分析证明,全寿命周期管理在设备管理中具有很大的实用价值。最后,结合SEC指标成本管理的特点和实施状况,指出了开展全寿命周期成本管理的重点工作。
[Abstract]:With the development of science and technology, new equipment and new equipment management concept are gradually applied to practical management, and new technical methods and management methods are actively explored to reduce the investment cost of equipment in the operation cycle. Improving the reliability of the operation equipment and maximizing the efficiency of the electrical equipment in its life cycle have become an urgent problem to be explored in power grid construction and cost management. In the process of equipment selection in the early stage of power network construction and design, the electric power enterprise only pays attention to the control of the initial input of the equipment, but often neglects the investment of the funds in various maintenance and failure stages after the equipment is put into operation. At the same time, the power enterprise does not have sound reliability analysis of power equipment and corresponding equipment cost analysis, which directly results in the high life cycle cost of the assets of electrical equipment. This paper begins with the analysis of equipment reliability, analyzes the shortcomings of equipment reliability analysis at present, and proceeds from the perspective of the concept of asset life cycle management. The application of life cycle management based on SEC index in Tangshan power grid is presented. The whole life cycle cost management is a comprehensive, scientific and advanced management concept and method. Its core is to manage all stages of the project life cycle as a whole, under the condition of the safe and reliable operation of the assets and the need to meet the use of the assets. In this paper, first of all, the reliability theory of equipment is studied, and then the reliability model of power equipment is determined. Secondly, the model and framework of safety, efficiency and cost index in life-cycle cost management are discussed. Based on the analysis of the current situation of power network equipment cycle cost management, this paper introduces the relevant theories, such as the evaluation method and the valuation principle, and makes a comprehensive and systematic introduction. In this paper, the application flow of life-cycle cost management in every stage of equipment operation is deeply studied. By introducing transformer equipment example, the comparison and analysis of each index value of SEC index management in actual equipment operation are carried out, and it is proved by comparison analysis. Life-cycle management is of great practical value in equipment management. Finally, combined with the characteristics and implementation status of SEC index cost management, the key work of developing life-cycle cost management is pointed out.
