【摘要】：电力工业作为国民经济的基础产业,以向用户提供廉价而充足,可靠和合格的电力为社会责任。安全可靠、优质、经济地供电是现代社会对电力系统的基本要求。配电网是至关重要的组成部分,是影响电力市场运行的重要因素。提高配电网的供电可靠性和供电质量,是实现人民安居乐业、经济发展、生活富裕的重要保证。规划是发展的前提,做好电网规划,对指导配电网适度发展,满足社会经济发展对电力的需求,具有先导作用。论文以兰考县配电网为工程实例,对工程实际中配电网规划的基本方法、基本理论、基本要求等问题进行了研究。分析了国内外配电网规划工作的研究现状,进一步明确了电网规划需要以目前电网现状为基础,结合当地市政建设和总体规划,并考虑大地区的电网建设,通过正确的电力需求预测,制定全面合理的方案,以指导地区性电网建设,满足国民经济增长和社会发展的需要。论文结合兰考县新型城镇化规划发展需要以及负荷基础数据的整理,采用分行业综合用电分析法、电力弹性系数法进行总电量、总负荷的预测,对未来规划水平年兰考县用电负荷的发展情况进行了分析和展望。结合电网规划的理论方法在工程实际中的应用和配电网规划设计技术导则,通过对兰考县配电网现状及历史运行数据的分析,对兰考县配电网目前存在的问题进行了归类整理,提出了未来规划水平年兰考县配电网具体的配电网建设方案,并进行了投资估算和效果分析。为地区建设“十三五”坚强配电网提供技术支撑和参考,具有较强的实用价值。配电网规划成果的落实,使得规划区域配电网的各项运行指标都有了明显的改善,包括:供电可靠性指标、电压质量指标、线损率指标、容载比、N-1等。科学合理的配电网规划是保证电网长期最优发展的基础。
[Abstract]:As the basic industry of national economy, electric power industry is responsible for providing customers with cheap, sufficient, reliable and qualified electricity. Safe, reliable, high-quality and economical power supply is the basic requirement of modern society to the power system. Distribution network is a vital component and an important factor affecting the operation of electricity market. To improve the reliability and quality of distribution network is an important guarantee for people to live and work in peace and contentment, economic development and prosperity. Planning is the premise of development. It has a leading role in guiding the moderate development of distribution network and meeting the demand of power for social and economic development. Taking the distribution network of Lankao County as an engineering example, the basic method, basic theory and basic requirements of distribution network planning in engineering practice are studied in this paper. This paper analyzes the research status of distribution network planning at home and abroad, and further clarifies that the power network planning needs to be based on the current situation of power grid, combining with local municipal construction and overall planning, and considering the power grid construction in large areas. In order to guide the construction of regional power grid and meet the needs of national economic growth and social development, a comprehensive and reasonable plan is made through correct forecasting of power demand. According to the needs of the new urbanization planning and development in Lankao County and the consolidation of the basic load data, the paper adopts the comprehensive power analysis method by industry and the method of electric elasticity coefficient to forecast the total electricity quantity and the total load. The development of power load in Lankao County in the future planning level is analyzed and prospected. Combined with the application of theory and method of power network planning in engineering practice and the technical guidelines of distribution network planning and design, the problems existing in distribution network of Lankao county are classified and sorted by analyzing the present situation and historical operation data of distribution network in Lankao County. The construction scheme of distribution network in Lankao county in the future planning level is put forward, and the investment estimation and effect analysis are carried out. It provides technical support and reference for the regional construction of "the 13th Five-Year Plan" strong distribution network, and has strong practical value. The implementation of distribution network planning results has made the planning of regional distribution network operation indicators have been significantly improved, including: power supply reliability index, voltage quality index, line loss rate index, capacity to load ratio, N-1 and so on. Scientific and reasonable distribution network planning is the basis to ensure the long-term optimal development of power grid.
