【摘要】：输变电建设项目可以缓解用电需求的供给压力，，确保电网的稳定运行，输变电工程项目的实施可以看做是保证居民用电和国家经济发展的基础。对输变电工程项目实施情况进行科学的综合评价，有利于衡量项目的整体施工情况，并能为后续工程项目实施提供决策依据。廊坊市杨芬港配套110千伏输变电项目是为满足区域乃至社会电力负荷需求，优化电网结构，减少网络损耗，提高供电质量和可靠性能，最终提升国民经济效益等需要而建设的。本文在阅读相关文献的基础上，提出廊坊杨芬港配套110千伏输变电工程综合评价的整体研究思路。本文首先介绍论文的研究背景及意义，然后介绍杨芬港配套110千伏输变电项目的基本情况，包括其设计依据规范，又从工程概况、线路选择方案、工程造价等方面详细介绍杨芬港配套110千伏输变电项目的四个子工程；统筹考虑该输变电项目的市场需求、经济效益、环境效益、技术水平、工程造价和路径合理性等问题，据此建立杨芬港配套110千伏输变电项目评价指标体系，最后应用模糊层次分析法对该项目进行综合评价研究。结果显示项目综合效益很好，可以缓解供电压力，满足当地负荷发展的需要，利于提升河北省供电的可靠性，同时为企业自身带来丰厚利润，还可极大推动社会经济效益；最后为该输变电工程项目提出相关建议，具有较强的实践和借鉴意义。
[Abstract]:Transmission and transformation construction projects can alleviate the supply pressure of electricity demand and ensure the stable operation of the power grid. The implementation of transmission and transformation projects can be regarded as the basis of ensuring the residents' electricity consumption and the national economic development. A scientific comprehensive evaluation of the implementation of power transmission and transformation projects is helpful to measure the overall construction situation of the project and to provide a basis for decision making for the implementation of subsequent projects. The 110kV power transmission and transformation project in Yangfen Port of Langfang City is built to meet the demands of regional and even social electric power load, optimize the power network structure, reduce network losses, improve the quality and reliability of power supply, and finally enhance the national economic benefits. On the basis of reading relevant documents, this paper puts forward the overall research idea of comprehensive evaluation of 110 kV power transmission and transformation project in Yangfen Port of Langfang. This paper first introduces the research background and significance of the paper, and then introduces the basic situation of the 110 kV power transmission and transformation project in Yangfen Port, including its design criterion, engineering overview, route selection scheme, In terms of project cost, four sub-projects supporting 110 kV power transmission and transformation project in Yangfen Port are introduced in detail. Considering the market demand, economic benefit, environmental benefit, technical level, project cost and route rationality of the transmission and transformation project as a whole, the evaluation index system of Yangfen Port supporting 110 kV transmission and transformation project is established. Finally, the fuzzy analytic hierarchy process is applied to the comprehensive evaluation of the project. The results show that the comprehensive benefit of the project is very good, which can relieve the pressure of power supply, meet the needs of local load development, promote the reliability of power supply in Hebei Province, bring rich profits for the enterprises themselves, and promote the social and economic benefits greatly. Finally, some suggestions are put forward for the transmission and transformation project, which has strong practical and referential significance.
