面向供电可靠性的配电网规划方法与实践应用

Planning Method and Its Application of Distribution Network Based on Power Supply Reliability

配电网是电力系统中直接面向用户的环节,对用户供电可靠性有着直接的影响。因此,在配电网规划中如何准确快速地评估配电网可靠性水平,以实现将电能可靠、经济地输送给用户已成为研究的热点。文中以中压配电系统为研究对象,通过从网络、设备、技术和管理4个方面分析供电可靠性的影响因素,进而系统地给出了面向供电可靠性的配网规划方法。该方法主要包含现状调研、方案制定与方案评估等几部分,有着较强的适用性和可操作性。最后通过对国内某城区配网的实践应用验证了该方法的可行性。

Distribution network is the user-oriented part of power system and has a direct impact on the reliability of power supply.In order to reliably and economically transmit the electrical energy to the user,how to quickly assess the reliability level of distribution network has become the hot topic of research.By using medium voltage distribution network as research object,this paper analyzes the factors that affect the power supply reliability from network,equipment,technology and management,and then systematically offers the method of distribution network planning based on power supply reliability.This method contains three major parts,which are status research,program development and program evaluation,and has a strong applicability and operability.Finally,the feasibility of the method is verified by the distribution network planning of a domestic urban distribution network.
