【摘要】：电力系统是整个国民经济或能源系统的一个非常重要的子系统,电力系统就是为用户提供满足需求的电力而存在和发展的,其中配电网是直接面对用户的组成部分,因此显得尤为重要。对于供电企业而言,合理的配电网规划就是寻找一种即节省费用,又可满足用户供电需求和可靠性的方法。配电网规划主要由电力负荷预测、电源规划和电网规划构成。电网规划又以负荷预测和电源规划为基础,在保证输电能力,满足各项技术指标的前提下使供电系统建设的费用最小。目前,北京市配电网建设存在着与城市建设发展不协调、负荷预测及电气计算准确性不高和配电网与主网的建设发展不协调等问题。本文结合准确的城市规划建设方案,对城市配电网进行合理分区,通过网格化的方法,实现对分区用电需求的准确预测,在此基础上,分区开展配电网规划,在原有地区主网和配电网的基础上,提出变电站点建设方案和配电站点建设方案,并在分区间完善区域配电网联络方案,保证互为备用,在满足地区用电负荷发展需求的同时,满足用户对供电可靠性的需要。本文选取北京市朝阳区作为配电网规划的试点。通过北京市朝阳区用电负荷的实际情况,将配电网进行网格化,准确进行分区负荷预测,在此基础上开展配电网规划,将为北京市其他区域配电网的规划建设提供可靠的参考依据,形成配电网规划的网格化方法,从而有效加强配电网规划的科学性。
[Abstract]:The electric power system is a very important subsystem of the whole national economy or the energy system. The electric power system exists and develops to provide the electricity to meet the demand for the user, among which the distribution network is the component that faces the user directly. So it is particularly important. For the power supply enterprises, the reasonable distribution network planning is to find a method that can not only save the cost, but also meet the demand and reliability of power supply. Distribution network planning is mainly composed of power load forecasting, power planning and power network planning. On the basis of load forecasting and power supply planning, power network planning can minimize the cost of power supply system construction on the premise of ensuring transmission capacity and meeting various technical targets. At present, there are some problems in the construction of distribution network in Beijing, such as the incoordination between the development of distribution network and urban construction, the inaccuracy of load forecasting and electrical calculation, and the development of distribution network and main network. This paper combines the accurate urban planning and construction scheme, carries on the reasonable partition to the urban distribution network, through the grid method, realizes the accurate forecast to the district electricity demand, on this basis, the district carries out the distribution network plan, On the basis of the original main network and distribution network, the paper puts forward the construction scheme of substation point and distribution station, and perfects the regional distribution network liaison scheme in each interval to ensure that it can be used for each other, while meeting the demand of local power load development. To meet the needs of users for the reliability of power supply. This paper selects Chaoyang District of Beijing as the pilot of distribution network planning. According to the actual situation of electricity load in Chaoyang District of Beijing, the distribution network is gridded, and the distribution network planning is carried out on the basis of accurate load forecasting. It will provide a reliable reference for the planning and construction of distribution network in other regions of Beijing, and form a grid method for distribution network planning, thus effectively strengthening the scientific nature of distribution network planning.
