[Abstract] With the accelerated development of power grid construction, a huge grid assets, the traditional way of asset management has been unable to meet the development needs of the new situation, we must accelerate the transformation of management philosophy. This paper discusses a new management, co-ordination to deal with security, performance and cycle costs relationship between the three, to improve the efficiency of the use of the power grid assets, reduce total life cycle costs, the grid assets Lean, the entire process of comprehensive management.
[Keywords] grid assets, full-cycle cost management.
Grid construction, renovation, operation and maintenance tasks are even more onerous, traditional management approach, there's many problems, such as the short life of equipment, inefficient use of technological input, high maintenance costs gradually emerging. Cycle cost management, in essence, is the system engineering theory in asset management.
Full-cycle cost management based on assets as a research object, starting from the overall goal of the system, and consider asset planning, design, procurement, construction, operation, maintenance, technical innovation, scrapped the whole process, to meet the security, performance under the premise pursuit of the asset life cycle cost optimal, and the scientific method to achieve system optimization.
Cost management is relatively weak.
. Limitations of power construction project cost control project cost control is only concerned about the cost of the construction period. Existing cost control and more building owners, design side, the construction side, cost control, cost control object is the construction of the project construction period or a stage of the construction period.
Project cost control object is the project cost, not pay enough attention to the project running costs from the point of view of the life cycle, the equivalent of the cost of the construction phase control, cost control is less than the cost of the construction phase control.
, Was caused by the other phases of the project cost control to consider the impact of the interaction between the various stages and the overall life cycle cost less fragmented internal relations of the various stages of the construction project cost which may cause certain stage of cost control effect increased costs, the higher cost of the entire life cycle of construction projects.
Grid assets cost management status quo. "Segmented" asset-based management, the various departments have different objectives, scope and focus of the various stages of management information can not be shared, the feedback evaluation mechanism is not perfect, the continuity of work is not effective enough, sufficiently sophisticated business process design, there are differences or conflicts between the systems, standards, lack of asset management, "the whole process of" assessment, pay more attention to the effectiveness of a point in time or over a period of time, resulting in asset management objectives are not completely unified, resulting in various stages asymmetric information, resulting in increased costs.
(A foundation ledger data is not accurate, and the actual quite different, not timely feedback correction, the lack of a long period of accumulation of basic data (2 data level is not high, can not achieve the direct acquisition of field data, statistics and analysis, information management should be strengthened, and (3 Financial Management Lean degree is not high, no cards linkage of the lack of total assets, the whole life cost budget and accounting mechanisms, two full-cycle cost management.
Full-cycle cost management in order to achieve the lowest cost of the asset life cycle, looking for an investment with the best combination of points in the operation and maintenance costs between the two, thus changing the fragmented relationship between the two, one-sided pursuit of an investment minimum practice effectively achieve The convergence of the various stages of the asset life cycle, which is very significantly reduce the overall cost of the asset life cycle, and improve the operational efficiency of the company's assets.
Composed of full-cycle cost of grid assets. Full-cycle cost of the power grid assets is the life cycle, the total cost paid by the following components:
(1) an investment cost of the power grid construction and commissioning period before formally put into operation, to pay a one-time cost.
(2 operating cost refers to the sum of all costs spent during grid operation, including: maintenance fees, can-consuming, labor costs, environmental costs, and other expenses.
(3 interrupt the cost of the loss of power, a power interruption to the power companies to reduce electricity supply and electricity sales income, a certain amount of economic losses caused to the user, interrupt the cost of the loss of power is determined by a number of factors. Currently, users of complain to interrupt the power supply is increasing every year.
(4) end-of-life costs, after the end of the product life cycle, clean-up, the destruction of the product is required to pay the costs, as well as the power channel.Links to free papers Download Center http://eng.hi138.com
2 full-cycle cost management.To carry out the assets full cycle cost management is the management of change, innovations and breakthroughs in terms of management style, working mechanisms and assessment methods need full range of asset management in the grid, update the concept of the whole process. Further promote grid development the transformation of the mode of accelerating the coordinated development of power at all levels, planning philosophy innovative, design standards continue to optimize and significantly reduce procurement costs, and continuously improve the level of the building. actively promote the standardization of production systems, information construction.
Good load forecasting, long-term planning, design: to extend the planning cycle, the development of 10 years to 20 years of long-term planning, and optimization of the technical and economic assessment approach, improve planning rolling update mechanism, raise a standard "two-oriented one" and "three links "guiding principles, multi-scheme comparison, optimization of design and engineering solutions.
Reasonable procurement, strict network: the lowest cost for the entire life cycle of the target, differentiated design bidding scheme, revised bid evaluation rules, increase equipment supervision efforts, strictly control the quality of network equipment, and strictly enforce the acceptance criteria and the system. Meanwhile, should avoid excessive equipment manufacturers, model complexity and inconvenience to the operation and maintenance, resulting in the increase in the cost of post-run maintenance.
Decommissioning and waste management: cleaning equipment, basic data and ledger assets, to establish a unified the retired asset management platform, improve the technical assessment methods, improve end-of-life asset disposal process and other related provisions, according to the value of the assets of the state and the use of a greater range to arrange the retired asset transfer, replacement and re-use grid asset life cycle to maximize the value in use.
Realize the asset and information management: the timely transmission of information and feedback at all stages of the asset life cycle management and key business processes are closely linked, forming a whole and lay a solid foundation for scientific decision-making to achieve overall optimization through the establishment of a unified assets electronic tag system, integrated asset real logistics, information flow and value flow, accounts and cards, consistency and linkage of objects, each stage of the asset management information sharing.
Transported equipment running lean: the promotion of online monitoring, evaluation and status of equipment maintenance, establish and improve the state-based security risk assessment mechanisms, optimizing maintenance strategies based on the status of the device, reasonable maintenance cycle, reduce equipment accompany repair, over repair, reduce maintenance maintenance workload and maximize economic benefits in the transport equipment.
Spare parts management: the establishment of a unified information management platform for spare parts, improve the trade-in, device rotation, replacement of assets, equipment refurbishment way to achieve information sharing and unified call of spare parts, spare parts in the company's system-wide to achieve regional across regions to optimize the allocation of the full life cycle of the spare parts to maximize efficiency.
3 the relationship between the cost and the safety and effectiveness of the whole cycle. Cycle cost management is an important means of optimizing the cost-effectiveness of the power grid assets. Cycle cost management is an important foundation to improve operational efficiency. The grid enterprises belonging to the basis of the service sector and utilities, important basic industries in the people's livelihood, and shoulder important political and social responsibility to ensure the safe and stable operation of the power grid is the primary task of the company is facing the one hand, the requirements in the operational phase of the asset formation early in the decision-making process has been fully taken into account, greatly reduce the assets of the possibility of health risks caused by the early stages of planning, design, bidding and construction, on the other hand, in the running of the asset-based full-cycle cost management concepts used in a variety of management methods, contribute to the operation and management level improved.
The full-cycle cost management is the key initiatives to improve the quality of assets to extend the useful life of equipment.
In the the grid asset life cycle costs, the failure caused the loss of a larger proportion of full-cycle cost management in the planning of the equipment or system design and bidding adequately consider the reliability factors, the cost of failure as a punitive costs discounted into the full life-cycle costs, a comprehensive analysis of the impact of the reliability of the whole life cycle cost, to help improve the reliability of equipment and systems from the source, so as to enhance the quality of transmission and distribution equipment assets and extend their useful life.
Third, the conclusion.
China is in the peak of power grid construction, asset size, fast growth, asset management mode, it is necessary to change the past "segment" management, process management model to unify the various departments objectives, optimize the various stages of business management strategy, whole process of optimal asset management. traditional grid cost management mode only attach importance to investment cost, do not attach importance to the running costs, only by hand, do not consider a state-of-the-art management tools; rely mainly on the corporate finance department, not pay attention to play the majority of employees enthusiasm, and therefore difficult to adapt to the requirements of the development of the grid. This requires innovation in the concept of cost management, to establish the concept of competition, new concept. effective concept, business concept, the legal concept of management thought is the soul, the management of the organization is to ensure the management methods conditions First, the rationalization of management organization, there is no guarantee on the organization, the enterprise is difficult existing human, material and financial organizations, it is impossible to maximize the overall benefits Secondly, management tools programmed full application network information system, not only can replace the complicated affairs of labor and can accelerate information processing, ease of management personnel to make the right decisions in a timely manner.
