【摘要】：电网规划是电网建设的重要指引和依据,是深入贯彻国家电网公司建设“一强三优”现代化电网要求的基础性工作。随着中央加快农村地区发展建设工作的推进,农村地区社会经济水平得到快速发展,同时对农村地区电网规划建设、安全水平、供电能力、服务质量提出了更高的要求。但是在目前农村电网的建设发展过程中,仍存在着对电网规划工作重视程度不够、规划理念滞后、水平参差不齐等问题,制约了电网建设发展的进程,导致用电需求与电网建设间的矛盾越发突出。以往针对性的开展电网规划研究工作相对较少,本文针对鹿泉区配电网的特点,深入分析问题,优化电网结构,加强技术经济比选,因地制宜的对鹿泉区本地的配电网进行了规划研究进一步促进电网健康快速发展。本文根据鹿泉区电网建设实际情况进行优化网络结构研究,主要进行了如下工作:首先本文第一部分主要是结合鹿泉的地区经济和社会发展的实际情况对鹿泉县配电网的现状进行分析,在对配电网的现状完全了解后,找到鹿泉配电网目前存在的主要问题。其次针对石家庄鹿泉地区丘陵平原结合的实际特点,对鹿泉地区配电网现状进行了分析,构建目标网架,指导近中期过渡方案。减少变压层次,各电压等级协调发展。通过加强配网站间联络,降低高压配电网容载比,低于导则下限,提高高压设备利用率。最后分析10kV电网网架优劣,并尽量减少规划中的结构种类,以简化运行方式;并结合“新农村、新电力、新服务”的发展战略,提高农村电网规划管理,提出建成“布局合理、技术适用、供电质量高、电能损耗低”的新型村级电网合理方案。
[Abstract]:Power network planning is an important guide and basis for the construction of power grid, and it is also the basic work for the construction of "one strong, three excellent" modern power grid by the State Grid Company. With the development and construction of rural areas being accelerated by the central government, the social and economic level in rural areas has been developed rapidly. At the same time, higher requirements have been put forward for the planning and construction of power grid in rural areas, security level, power supply capacity and service quality. However, in the process of rural power grid construction and development, there are still some problems, such as insufficient attention to power network planning, lagging planning concept and uneven level, which restrict the process of power grid construction and development. As a result, the contradiction between electricity demand and power grid construction is becoming more and more prominent. According to the characteristics of distribution network in Luquan area, this paper deeply analyzes the problems, optimizes the power network structure, and strengthens the technical and economic comparison. According to local conditions, the local distribution network in Luquan area is planned and studied to further promote the healthy and rapid development of power grid. According to the actual situation of power network construction in Luquan District, this paper studies the optimization of network structure. The main work is as follows: first of all, the first part of this paper is to analyze the current situation of Luquan county distribution network in combination with the actual situation of regional economic and social development of Luquan, and after fully understanding the current situation of distribution network, Find out the main problems existing in Luquan distribution network. Secondly, according to the actual characteristics of the combination of hilly plain in Luquan area of Shijiazhuang, the present situation of distribution network in Luquan area is analyzed, and the target grid frame is constructed to guide the transition scheme in the near and medium term. Reduce the voltage level, each voltage level coordinated development. By strengthening the communication between distribution websites, the capacity / load ratio of high voltage distribution network is reduced, which is lower than the lower limit of the guide, and the utilization ratio of high voltage equipment is improved. Finally, the advantages and disadvantages of 10kV grid network are analyzed, and the types of structure in planning are reduced as much as possible to simplify the operation mode, and combined with the development strategy of "new countryside, new electricity, new service", the planning and management of rural power grid is improved, and the reasonable layout is put forward. Technical application, high quality of power supply, low power loss "new village power grid reasonable scheme."
