The Research On Comparison Method Of Power Network Planning Scheme Based On Life-Cycle-Cost Management

Power grid as part of end of the electricity network directly connected to the userthe entire electric power system on the user’s supply capacity and quality are reflected through the gridthus the power supply indicators are actually the entire power system structure and operation characteristics of reflected.With the development of the national economyscience and technology and the improvement of people’s living standards and people’s growing demand for electricity and dependenceincreasing demand for the safe and stable economic powerpower grid construction investment continued to increase.Traditional power network construction project cost management of construction project construction costand after the transfer of the facility’s operation and maintenance costs are rarely considered from a long-term point of viewfacilities for future operations cost much more than the capital cost.Thereforethe construction programme with the lowest cost in the project Life-Cycle perspective is not necessarily optimal.To optimize the power construction project planning processconsidering the project Life-Cycle costsstrikes the best balance between cost is the urgent need to address the problem.In this situationapplication Life-Cycle cost(LifeCycleCost,LCC)concepts and theories for network planning will be more advantageous than the traditional planning methods.First analysis of the whole process of construction and operation of power gridsfrom equipmentsystemsand projects based on the long-term economic benefits of fully into account in the planning design manufacture acquisition installation operation maintenance updates until scrapped during the whole Life Cycletotal expenditures combined.Scope of analysis including project planning design construction operation and maintenanceand residuals recyclingin more than one alternative scenarioselect a programme within the Life-Cycle cost minimumestablished a planning programme Life-Cycle cost(LLC)evaluation model and method.Established in accordance with this article the total Life-Cycle costs(LLC)evaluation model of network planning project selection work carried out with specific cases.Mains main examples of 110,000 volts objective gridwind outMetro traction transformer voltage selectionline typessuch as case studies in the fieldsdistribution network mainly illustrates the plum Brook Lake areacity power grid planning in shaodong County programme selection.Results showed that this power grid planning Life-Cycle cost(LLC)evaluation model and methodcan be used to solve network planning cost analysisapplied in practical workthe analysis results and engineering application of high value.
