Research On The Determination Of Reasonable Cost Range Of Power Grid Production Technological Transformation Project

This paper proposed a method to determine the reasonable cost interval of power grid production technological transformation project based on Kernel Density Estimation (KDE). The general idea of the study of reasonable cost interval is to select sample data, determine the sample estimation method, remove the outlier data, and finally calculate the reasonable unit cost interval of power grid. The general idea of the study of reasonable cost interval is to select sample data, determine the sample estimation method, remove the outlier data, and finally calculate the reasonable unit cost interval of power grid technical transformation project. Taking the actual data of the disconnector replacement project as an example, this paper made statistics of the reasonable cost range of the power grid production technological transformation project, which provides a new idea and method for the reasonable determination of the cost range in the case of large amount of data.
