【摘要】：提高配电系统的供电可靠性是配电自动化系统建设的重要目标,但需考虑配电自动化设备的经济成本,且实际工程中通常是分阶段拨款。提出一种考虑供电可靠性和经济成本的配电自动化终端布点优化的动态规划方法,混合使用多种类型配电终端,在架空线安装故障指示器、电压时间型终端、电压电流型终端,在电缆线安装故障指示器、二遥终端和三遥终端,根据自动化终端类型确定故障影响模式。运用JAVA语言进行编程,实现从XML文件读取配网数据。以开关为边界划分配电网的区域节点,采用开源的图形库JGraph T存储配网拓扑信息。考虑故障停电情况,以用户年平均故障停电时间为评价供电可靠性的指标,分别建立以可靠性指标为优化目标和以投资总额为优化目标的配电自动化终端布点优化的动态规划模型。使用建模系统GAMS求解模型,得到配电终端布点优化结果。采用某地区区域配电网自动化终端布点规划作为算例验证,结果显示了该方法的可行性与优越性,为类似实际工程提供借鉴与依据。
[Abstract]:To improve the reliability of distribution system is an important goal of the construction of distribution automation system, but it is necessary to consider the economic cost of distribution automation equipment, and the allocation of funds in practical projects is usually phased. In this paper, a dynamic programming method for distribution automation terminal placement optimization considering power supply reliability and economic cost is proposed. It uses a variety of distribution terminals, installs fault indicators, voltage-time terminals and voltage-current-type terminals on overhead lines. Install fault indicator, second remote terminal and third remote terminal in cable, and determine the failure mode according to the type of automation terminal. JAVA language is used to program to read the distribution network data from the XML file. The switch is used as the boundary to divide the regional nodes of the distribution network, and the open source graphics library JGraph T is used to store the topology information of the distribution network. Considering the condition of power failure, the average annual failure time of the user is taken as the index to evaluate the reliability of power supply. Dynamic programming models of distribution automation terminal placement optimization with reliability index as optimization objective and total investment as optimization objective are established respectively. Using the modeling system GAMS to solve the model, the distribution terminal distribution point optimization results are obtained. A regional distribution network automation terminal layout planning is used as an example. The results show the feasibility and superiority of the method and provide reference and basis for similar practical projects.
