| Electricity as an important basis for national economic development, industry, able to provide strong protection for economic and social development and the demand for energy. In recent years, although many factors affecting the national grid for power transmission engineering company has promulgated a series of corporate standards, but due to the design capacity, review mechanisms, human intervention, resulting in project design varies, some failed the program is also designed to meet the standards to be implemented, resulting in failure to achieve the expected return on investment projects, but also to the system is running lay hidden. In order to effectively address this issue, excluding the impact of human factors on the design, we must establish a scientific and feasible substation engineering design evaluation mechanisms to ensure the quality of the project design meet the requirements.First, this paper analyzed the theoretical results in substation construction projects at home and abroad; secondly, according to the Ministry of Housing “35KV-110KV” substation engineering design specifications" and index construction principles, from the evaluation of the necessity of construction, site selection and reasonable assessment, evaluation of the advanced nature of the electrical construction, civil construction part of the evaluation, economic evaluation six aspects of the design to build a substation book program evaluation project evaluation system preliminary design plan; and then summarizing the advantages and disadvantages of various comprehensive evaluation method based on the establishment of a projectbased substation matter element Model of preliminary design program evaluation model and select the G1 method to determine the index weight; Finally, take Muren 110 KV substation project for example, to verify the validity of the index system operability and models, to provide reference for the other substation project preliminary design evaluation. |
