摘　　要： 为了方便对韶关配网线路的资产、运行及用户进行综合管理、对线路线损和相关设备进行分析查询,为供电局各个部门提供配电网基础数据,针对韶关10kV配网系统特点,以Microsoft Visual Studio.NET2003作为软件开发平台开发了基于Autocad2004二次技术的集图形、数据、网络结构、理论计算为一体的可视化配电管理系统。该系统根据配电网的结构特点,提出了一种计及网络开关状态的逆流搜索方法;分析了分布式电源在配电网中的实际运行状况和相应的潮流计算方法;根据无功精确矩确定无功补偿点遗传算法确定补偿容量,并提供杆上补偿和变压器低压侧补偿方式作为降损措施。该系统能有效地降低绘制配电网工程图的难度,提高数据录入的准确性和效率并提供韶关配电网络技术降损综合有效措施。 To make it convenient for Shaoguan Power Supply Company to manage the distribution line assets, users and operation, to provide the basic distribution data to the sub-departments, to analyze the line losses, to optimize the reactive compensation, and to provide an enterprise information platform with IT application solution, a visual distribution management system （VDMS） with a fully graphical man-machine interface based on Autocad2004 secondary development technology was developed, with the functions of drawing, search, energy loss computation and synthetic analysis. An upstream searching technique considering the state of switches was introduced to analyze the topological structure of the network, forward/backward sweep method was used to calculate the flow in view of the dispersion small power sources, and accurate reactive power moment was adopted to work out the compensate nodes and the capacity. The pole-compensation type and the low-vohage-side-of-transformer-compensation type are available in this management system. Practical examples show that this system enhances the precision and efficiency for inputting a large number of distribution data and provides convenient, rapidly accessing and intuitional functions of inquiry and statistic. It realized the integrity of graphics, data, calculations, analysis and management.
