Research On The Substation Secondary Electric Design & Management Based On The Life Cycle

Through analyzing the problems in the design,construction and equipment of the secondary electric system in substation,refer to the operation and maintenance experience,from a designer’s point on each stage of project construction,to ensure the safe operation of the grid and reliable power supply.Introducing of life-cycle concept proposed substation design modular design in order to reduce the transformation and expansion of impact on the substation that in the life-cycle.By design recommendations for improvement of the environment,to address the environmental impact of components and equipment life,and put forward reasonable suggestions for equipment design.Based on life-cycle-cost that the substation secondary equipment electronic,computer equipment replacement fast,with the bathtub curve analysis of vulnerability component life-cycle,the paper view is designers signed equipment maintenance cycle and more specifically the number of spare parts in the whole project in the technology agreements.By proposing a new model,provide for spare parts storage more viable long-term preservation solution.
