Cable Selection Model Based On Carbon Emission

In the context of the global development of low-carbon economy,in response to the national development requirements and people's desire for low-carbon society,more and more enterprises have joined in the work of carbon emission reduction.As the electric power enterprise is a typical large-scale carbon emission enterprise,burning fossil fuel as the main energy source,it is duty bound in the carbon emission reduction work.As an important participant in the carbon emission trading market,electric power enterprises should constantly strengthen their own capacity building,tap the potential of carbon emission reduction within enterprises,strengthen communication with other enterprises,and actively promote the construction and improvement of the national carbon trading system.As we all know,electric power enterprises have huge potential for carbon emission reduction.For electric power enterprises,to achieve the goal of carbon emission reduction is very important in promoting their own brand value,fulfilling their social responsibilities,and increasing economic benefits.At present,electric power enterprises have begun to pay attention to the measures and effects of carbon emission reduction,and there are a lot of domestic and foreign literatures discussing what measures electric power enterprises should adopt to achieve carbon emission reduction,which are good methods and articles.However,no matter the measures of carbon emission reduction of electric power enterprises,or the research projects and papers of experts and scholars,they are mainly concentrated in the power generation ring of electric power enterprises The measures to achieve carbon emission reduction in the section often ignore the relevant carbon emission research and carbon emission reduction measures in the transmission process of power grid.In view of this,this paper attempts to deeply study the transmission process of electric energy in the grid,find out its carbon emission law,and on this basis,explore the possibility of carbon emission reduction and specific operation methods for power enterprises in the process of transmission of electric energy.In order to discuss the transmission process of electric energy and how to achieve the goal of carbon emission reduction in this process,the first step is to discuss from the core of the transmission process of electric energy cable.As we all know,after generating power at the generation end,power enterprises need to reduce voltage through high-voltage grid at all levels,and finally convert it into household voltage to be transmitted to customers.Cables with different voltage levels will have different process requirements and working conditions.In the same voltage level,a large number of different types of cables work together in the same voltage level due to the influence of many factors such as the purchase batch of cables,process requirements,etc.Due to the influence of different factors such as the selected materials,cross-sectional area and length of wires,different cable resistivities result in different types of cables.Under different operating conditions,cables will have different operating conditions and power loss conditions,which results in different line loss rates and very large differences between different types of cables under the same voltage level.Under the same voltage level,there are dozens of hundreds of models of cables available for electric power enterprises to choose.However,according to the understanding from the relevant staff of the purchasing department of electric power enterprises,at present,when purchasing cables,the electric power enterprises only use the purchase price of cables as the necessary condition for cable selection on the premise of meeting the process requirements,instead of purchasing the cables produced during the operation period The cost of raw carbon emissions is added to the cable selection as one of the considerations.There are many reasons for this.The most important reason is that at present,the domestic carbon trading mechanism is still in the stage of exploration and improvement.From the perspective of short-term operation,the extensive cable selection mode of power enterprises will not have adverse consequences.But from the perspective of long-term operation,the cable selection mode of power enterprises will not only increase the future power grid operation cost of power enterprises,At the same time,it is not conducive to the electric power enterprises to carry out carbon emission reduction work and achieve the ultimate goal of carbon emission reduction.As the main component of power grid and the important carrier of power transmission,cable is an indispensablepart of power enterprises.Power enterprises should reduce the total amount of carbon emissions in the process of power transmission from the source,reduce the cost of carbon emissions in the process of power transmission,and finally achieve the goal of carbon emission reduction through reasonable and scientific cable selection.To sum up,this paper takes the realization of carbon emission reduction of power enterprises as the goal,the reduction of carbon emission of power enterprises in the process of power transmission as the research direction,the selection of cables as the starting point,combined with the actual situation,puts forward the method of optimizing the selection of cables for power enterprises,establishes the cable cost model based on carbon emission,and will collect the data-data of all 110 k V cables in X region The carbon emission law of different types of cables under the voltage level of 110 k V in X area is found out.Finally,through the verification of the calculation results,it is concluded that adding the carbon emission cost of the cable to the selection factors of the cable is in line with the actual operation of the cable and the requirements of the current society.In the future,when selecting cables,the purchasing department of electric power enterprises should consider the carbon emission cost of cables,and make the optimal solution of cable selection,which can not only reduce the operating cost of power enterprises in the transmission link,but also reduce the carbon emission of power enterprises in the process of power transmission,and ultimately achieve the goal of carbon emission reduction of power enterprises.
