Design Of Transformer Substation Based On Life-cycle Cost

With China’s economic development has entered a new norm, from high growth to lower the high-growth situation, should inherit and carry forward the national grid results and years of asset management experience, continue to use new methods and models to strengthen existing and future asset management, thus visible to the whole life-cycle management of existing and currently planned substation is very necessary. Life-cycle cost of substation engineering based, to achieve low input, high output, low emissions, can be recycled production model, to achieve a comprehensive, coordinated, the application of new technology to improve resource utilization. Through the full life cycle cost model design, substation project in the coming decades operations more effectively achieve its function, reduce natural, adverse effects on human society and achieve sustainable development, promote resource-saving and environment-friendly building society.In the process of urban development, urban power substation plays an essential role, and a huge investment, only a 110kV substation investment amounted to 3000-4000 yuan, such a large amount of investment, and only be able to use during the design LCCA methods research, analysis and control, in order to receive good results.In this paper, the principle of life-cycle costs, combined substation design-related technical issues, the general method of substation design discourse analysis theory based on the full life cycle. For basic equipment in substations, transformer, power distribution equipment, protective equipment, such as secondary math models are established. Finally, the effect of the cost-effectiveness of a comprehensive assessment and detailed engineering data examples illustrate, draw the optimal solution, and explain This method is feasible in substation design.
