The Post Evaluation Of The 220kV Wushan Power Transmission And Transformation Project

With the growth of state investment in power grid and the upgrading of technologies,the traditional management method for the project is unable to satisfy the present demands anymore.In particular,the essential development status and the attention paid to the project post-evaluation are far from adequate.How to summarize and refine the problems in the project implementation and operation through the project post-evaluation of grid reconstruction project and how to improve them on a management level of grid reconstruction project by overall prediction,planning and guidance on the future grid reconstruction project are also very imminent problems.In this paper,the author launched the research on the post-evaluation of grid reconstruction project based on the characteristics of grid construction project and combined with the actual problems in such a project,including the selection of post-evaluation methods,the determination of post-evaluation contents and the design/establishment of the model of relevant indexes,and solved the problems in the investment timing,investment scale and interest evaluation of the reconstruction project.Through the classification study on data,combined with the accessibility of data,the author determined the electricity purchase price and load capacity for the unknown data to be predicted,and used to time sequence to implement the prediction.Then,the author determined the evaluation indexes of the grid reconstruction project in management level,technical level,economic interest level,project impact in accordance with the basic principle of the establishment of index system,and combined with the classification of project post evaluation contents.Integrating the actual characteristics of grid reconstruction project,the author further refined the various indexes,constructed the evaluation index system of grid reconstruction project and determined the contents as well as the evaluation standards of all indexes.Finally,the author took the grid reconstruction work of the 220 kV Wushan Power Transmission/Transformation Project as the example,collected data related to the post-evaluation contents of the reconstruction project,made calculation on all concrete indexes by applying the post evaluation index system of grid reconstruction project proposed in the paper,conducted prediction by using the model for relevant data,conducted analysis and verification on all indexes by using comparative analysis,comprehensive evaluation and other methods,and ultimately obtained the conclusion of the post evaluation of grid reconstruction project.Through the analysis,the author authenticated the practicability of the post evaluation system of grid reconstruction project,broadened the thinking of the post evaluation work of the reconstruction project,forged the foundation and played a positive role for its subsequent improvement.
