【摘要】：电网是电力系统的重要组成部分,直接面向电力用户,是承上启下的关键环节,是改善民生的重要基础设施。近年来国网每年要求对各地市电网进行滚动规划修编工作,且从相关方法论高度重新认识电网,量化评价电网规划方案的优劣。由于传统规划普遍缺少对规划后的电网进行系统的评价,为此,迫切需要研究评价现有电网的关键指标与支撑性指标以及之间的量化关系,科学合理的制定电网规划评价方法。本文通过研究当前影响江苏电网正常稳定运行的关键性因素以及相关支撑性因素,从安全性、可靠性、经济性、优质性、智能性等五个方面展开深入的研究和分析,根据分析结果选择合适的指标,建立了一套可以对配电网电力专业现状或未来规划进行合理评估的指标体系。接下来按照模糊综合评价法的分析步骤,并结合德尔菲法(专家法)和层次分析法等分析方法,对整个指标体系进行深入梳理,通过对指标重要性进行分级和权重的设定,最终得到一套完整、可量化的电网诊断分析的评价标准,用于指导规划工作。最后,根据研究分析的成果结论,选取南京电网模型作为规划案例进行实例论证,通过与北京、上海等先进城市进行横向比较,寻找差距,并对规划项目实施之后的电网进行评估分析,进一步说明和验证研究成果的科学合理性和可行性。根据验证结果,至2030年,南京电网的评分将由81.08提高到97.71分,满足预期目标,将全面建成苏南现代化电网。
[Abstract]:Power grid is an important part of power system, which is directly oriented to power users, is the key link between the preceding and the following, and is an important infrastructure to improve people's livelihood. In recent years, the national network needs to carry on the rolling planning and compilation work to each city power network every year, and reconsiders the grid from the related methodology height, quantificationally evaluates the power network plan superiority and inferiority. Due to the general lack of systematic evaluation of the planned power network in traditional planning, it is urgent to study the quantitative relationship between the key indicators and the supporting indexes of the existing power network and to formulate a scientific and reasonable evaluation method for the power network planning. By studying the key factors and related supporting factors that affect the normal and stable operation of Jiangsu power grid at present, this paper carries out in-depth research and analysis from five aspects: safety, reliability, economy, quality, intelligence, etc. According to the analysis results, a set of index system is established which can be used to evaluate the current situation or future planning of power distribution network. Then, according to the analysis steps of fuzzy comprehensive evaluation method, combined with Delphi method (expert method) and Analytic hierarchy process (AHP), the whole index system is thoroughly combed out, and the importance of the index is classified and the weight is set. Finally, a set of complete and quantifiable evaluation criteria for power network diagnosis and analysis are obtained, which can be used to guide the planning work. Finally, according to the results of the research and analysis, the Nanjing power grid model is selected as a planning case for demonstration, through horizontal comparison with Beijing, Shanghai and other advanced cities, to find the gap. The evaluation and analysis of the power grid after the implementation of the planning project are carried out to further explain and verify the scientific rationality and feasibility of the research results. According to the verification results, by 2030, the score of Nanjing Power Grid will be raised from 81.08 to 97.71, which will meet the expected goal and build the modern power grid in southern Jiangsu.
