LCC-Based Reconstruction Schemes of 10 kV Distribution Lines

Convenient and practical criteria are formulated to evaluate indexes such as line types,load rate and operation time.Life Cycle Cost(LCC)model of distribution line is established,and life-cycle cost minimization is pursued with the equipment life cycle cost as the indicator for equipment investment evaluation.The paper aims at the optimal solution through quantitative assessment in order to guarantee line security,economical indicators and corporate overall benefits.
