The Implementation And Evaluation Of The Intelligent Reconstruction Project For Xuchang Substation

Xu Chang substation is so far the most perfect substation system’ Communicating standard. It has turned into the developing direction owing to IEC 61850 standard digitization transformer substations. Operation and administration substation will bring about far-reaching influence in our country. At present, the IEC 61850 standard is very few in routine operation substation project application. It works basically as the standard of the communications protocol, which is not enough. It does not applicable in the conventional substation equipment technology application; therefore there are still many problems to be solved. This paper briefly introduces the development trend of digital substation, the IEC 61850 standard features, and analyses the feasibility of status and xuchang substation digitization. Then, it undertakes a comprehensive demonstration of the xuchang substation intelligent transformation project management plan, technical scheme, problems, and count enneasures. Finally, based on the design of reconstruction project of xuchang intelligent, a comprehensive evaluation was summarized in the thesis, and it also gives the prospect of the next research direction of digital substation in operation and management. The main research contents are as follows: xuchang substation digitization feasibility argumentation, technical solutions and management discussion program, project-related indexes, established quantitative model and the changes. which comprehensive evaluation of the project engineering brings. Finally, through a comprehensive analysis and evaluation, the thesis introduces the new changes the digital transformation will bring to the substation operation, maintenance, economic efficiency, and technology efficiency; and it gives the direction prospect of digital substation after the transformation.In this paper the development status of the intelligent substation and its overall structure are introduced, and application of fuzzy comprehensive evaluation method of 110 kV Xuchang substation intelligent transformation effect of comprehensive evaluation, from the aspects of the technical indexes of the project, economic benefit indexes, social benefit index analysis of the effect of implementation of the project, also from an overall point of view the combination of quantitative analysis and qualitative analysis method to assess the project, so as to ensure the objectivity and scientific assessment of the project. At first, this paper describes the development status of a comprehensive assessment of the project related theory and the theory at home and abroad; secondly, it describes the multi-level fuzzy comprehensive evaluation model of the theory and modeling steps; then, the 110 kV Xuchang substation intelligent transformation effect were comprehensive evaluation.Evaluation results show that the established evaluation index system is very comprehensive, evaluation of intelligent substation reconstruction project integrated the qualitative and quantitative methods, this study confirmed that the multi-level fuzzy comprehensive evaluation model can be well applied to comprehensive assessment of China’s intelligent substation reconstruction project.
