Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with accompanying drawing.
See also Fig. 1, the process flow diagram of the computing method of the overall life cycle cost of Fig. 1 cable of the present invention.The computing method of the overall life cycle cost of cable of the present invention mainly comprise the steps:
Step 1: the present worth of calculating the initial Meteorological CI of described cable.Concrete, the initial Meteorological of described cable comprises Installation and Debugging expense and some other fees of the purchase commodity of described cable body, described cable body, such as the special debug-item expense of cable body and the state monitoring apparatus expense of purchasing possibly.The initial Meteorological of described cable can be the summation of purchase commodity, Installation and Debugging expense and the other fees of cable body, and the initial Meteorological of described cable also can comprise at least a expense in purchase commodity, Installation and Debugging expense and the other fees of described cable body.
The purchase commodity of described cable body comprises described cable body purchase expense, specific purpose tool expense, first standby redundancy expense, Site Service expense, supplier's traffic expense, premium of insurance.The purchase commodity of described cable body can buy for described cable body take, the summation of specific purpose tool expense, first standby redundancy expense, Site Service expense, supplier's traffic expense, premium of insurance, the purchase commodity of described cable body also can comprise described cable body buy take, specific purpose tool takes, the first at least a expense in standby redundancy expense, Site Service expense, supplier's traffic expense, the premium of insurance.Preferably, described cable body purchase commodity is the price after technology and scope of supply adjustment take producer's price as the basis.
The Installation and Debugging expense of described cable body mainly is the cable laying mounting cost, comprises building mounting cost, proprietor's traffic expense, the front debugging charge of putting equipment in service.The Installation and Debugging expense of described cable body is for building the summation of the debugging charge before mounting cost, proprietor's traffic expense, the putting equipment in service, and the Installation and Debugging expense of described cable body also can comprise at least a expense of building in the front debugging charge of mounting cost, proprietor's traffic expense, putting equipment in service.
The initial Meteorological CI of the described cable that calculates is the present worth of the initial Meteorological CI of described cable.After obtaining present worth, multiply by again (1+i)
aObtain corresponding final value, wherein, i represents interest rate, and a is the life-span of cable body, take year as unit.Here and hereinafter, present worth refers to calculate the then value of initial end of year, and final value refers to calculate the then value of time termination.
Step 2: according to the present worth of each annual operating cost CO in the life cycle management of described cable, calculate the present worth of the operating cost in the described cable life cycle management.Concrete, described each annual operating cost comprise described cable year wear and tear expense and annual day-to-day operation patrol and examine expense.N year operating cost is the summation that described cable n year wear and tear expense and n year day-to-day operation are patrolled and examined expense, certainly, described each annual operating cost also can comprise cable year wear and tear expense and annual day-to-day operation patrol and examine at least a expense in the expense.
The described annual day-to-day operation expense of patrolling and examining comprises tour cost of equipment, the Master Cost of Daily Round Check needs and makes an inspection tour labour cost.Year day-to-day operation patrol and examine that action comprises that environment is maked an inspection tour, specialty checks, ground temperature detects, induction current test, spy are patrolled, infrared detection, ultraviolet detect.The described annual day-to-day operation expense of patrolling and examining can be the summation of making an inspection tour cost of equipment, Master Cost and making an inspection tour labour cost, and described annual day-to-day operation is patrolled and examined expense also can be for making an inspection tour at least a expense in cost of equipment, Master Cost and the tour labour cost.Further, cable year wear and tear expense=cable year loss of electricity * cost electricity price=(year AC resistance loss of electricity+year dielectric loss electric weight) * cost electricity price; Annual daily walkaround inspection expense=(environment is maked an inspection tour expense+professional inspection charge+ground temperature testing cost+induction current testing expense+spy expense of patrolling+sampling observation expense+other expenditure) * unit length.
N year operating cost CO in the life cycle management of the described cable that calculates is the present worth of described cable n year operating cost CO.After obtaining present worth, multiply by again (1+i)
-n, can obtain the present worth of the life cycle management of cable corresponding to n year operating cost CO.According to the principle of similitude, utilize said method, can obtain respectively spending operating cost in the life cycle management of described cable, thereby present worth of the life cycle management of the cable that each degree operating cost is corresponding is cumulative, can obtains the present worth of the operating cost in the whole cable life cycle management.After obtaining present worth, multiply by again (1+i)
