The full-life cycle cost control of power grid construction projects means that from point of whole social view the full-life cycle cost control of power grid construction project is taken as a controlled object to analyse mutual relations between various stage costs,and various key elements costs during the whole cycle through certain techniques and methods.

It deals not only with the influence of environment on structures,but also with types,functions and importance of structures based on the theory of life cycle cost(LCC).

In this paper, the 220kV Cuo-buling substation of Qingdao is taken as analised object, to which the method of life cycle cost (LCC) was introduced.

The paper introduces the concept of life cycle cost, analyses the life cycle cost of government project procurement, establishes estimation methods of LCC, and introduces the choice of parameters in estimation methods.

Based on the application of the theory of total life cycle cost analysis and the system efficiency analysis in the comprehensive evaluation of housing structure system,a(comprehensive) evaluation index system was set up.

The LCC Research of Electrical Equipment Based on CA Theory;

Decision-making Analyse of Electric Substation s Construction Based on Life Cycle Costs;

With practical engineering examples,the paper analyses and compares the life cycle costs between cast-in-situ foundations and precast foundations.

Power companies are able to obtain greater and more long-term economic benefits with the application of life-cycle cost(LCC) in power grid planning.
