The Utility Research Of Investment Return Analysis Of Distribution Network Planning

Investment return analysis is one of the most important componentof the distribution network planning, is the guarantee for scientificdecision-making of power grid construction projects, reduce and avoidmajor mistakes, an important means to improve the company economicbenefits and ensure safety in production. In the process of power gridconstruction, renovation, with small investment gains, investment income,distribution network planning is always of concern.Aiming at the shortcomings of existing evaluation method fordistribution network, the utility analysis of income distribution networkplanning. First establish the income distribution network planninganalysis index, study confirmed as lines or equipment current limit on theeconomy of scope. Secondly, analysis method of practical researchplanning income distribution network, the calculation model and thebranch current line of10kV power supply or average current calculationmodel, calculation process and the corresponding algorithm is givenplanning profitability. From childhood to the components and devices ofthe price difference of the individual, as the starting point,comprehensively considering the effects of various factors, such as theremaining cost, new or retrofit scheme was abandoned after the line orequipment cost, realize the quantitative analysis of profitability. Finally,combined with case analysis of the existing substation, by calculation,test the validity of this method.
