Description

一种基于能源控制器公变的台区停上电快速定位方法
技术领域
本发明涉及低压台区智能电网技术领域,特别是一种基于能源控制器公变的台区停上电快速定位方法。
背景技术
随着社会的发展,人们对供电可靠性的要求越来越高,保证用户的持续可靠用电已经成为供电公司最为关心的考核指标。传统的停电抢修停留在客户投诉阶段,随着宽带载波技术的深化应用,供电公司可以通过电能表设备停电事件上报,第一时间确认停电的用户有哪些,但无法具体定位到停电的源头,只能挨家挨户排查,耽误抢修时间。
发明内容
本发明针对现有技术存在的不足和缺陷,提供了一种基于能源控制器公变的台区停上电快速定位方法。为实现上述发明目的,本发明采用如下技术方案:通过微电流发送与识别技术梳理低压载波台区的物理拓扑关系,根据基于宽带载波深化应用技术上报的载波从节点停电事件,快速定位低压载波台区停电源头,协助供电公司工作人员精准抢修。
一种基于能源控制器公变的台区停上电快速定位方法,包括以下步骤:
步骤1:根据特征电流式台区拓扑识别技术,配合带有特征电流发送和识别的智能感知设备,实现台区拓扑关系的准确识别;
步骤2:能源控制器公变对台区拓扑关系的识别记录归一化梳理,理清台区设备的父子关系,并生成一组或几组拓扑结果;
步骤3:能源控制器公变在收到台区设备停电的上报信息后,将该停电设备在拓扑关系中的对应位置置位;
步骤4:重复步骤3,一直收集台区设备停电信息,直至收集完成或者到达一分钟的收集时长限值;
步骤5:根据已收集的台区设备停电信息,配合已知的台区物理设备拓扑关系,生成台区设备停电拓扑结果;
步骤6:根据停电拓扑关系,生成主节点停电事件,查找距离根节点拓扑距离最近的停电主节点设备,生成关键节点停电事件,事件通过能源控制器上报给局方主站。
进一步地,所述步骤1带有特征电流发送和识别的智能感知设备,包括带有特征电流发送功能的智能电表、载波模块以及带有特征电流发送和识别功能的智能断路器、表箱监测单元。
进一步地,所述步骤2中的拓扑结果包括各个分级主节点以及其下属一级的子设备,不作多级延申,首先根据特征电流识别信息,确认所有父子节点的单级关系,并根据主节点分组,其次遍历所有设备节点,确认其拓扑深度级别,设备节点通过查询父节点查找到根节点(即能源控制器本身)的次数N定义为拓扑深度级别。
进一步地,所述步骤5中的台区设备停电拓扑结果包括各个停电的分级主节点以及其下属一级的停电子设备,包括各个设备节点的拓扑深度级别。
进一步地,所述步骤6中查找距离根节点拓扑距离最近的停电主节点设备,是指遍历查找各个分支上停电的主节点设备中拓扑深度最小的节点,具体方法是从拓扑深度级别为1的设备节点开始检查是否停电,停电的定义为关键节点停电,并生成关键节点掉电事件,未停电继续向拓扑深度级别+1的子节点进行检索判断,以此类推,直至找到所有分支上停电的主节点设备中拓扑深度最小的节点。
本发明的有益技术效果:通过微电流特征信号识别技术实现台区物理拓扑的精准识别,对物理拓扑关系预处理,获取各设备节点的拓扑深度级别,结合基于宽带载波技术上报的设备停电事件,梳理出停电设备的物理拓扑结果,通过对停电拓扑结果的分析溯源,可以精准的找到导致低压台区大范围停电的根源,协助供电公司工作人员快速定位、精准抢修,进而实现提高用户用电持续稳定的目的,具有很强的推广意义。

具体实施方式
为了使本发明的目的、技术方案及优点更加清楚明白,以下结合附图及实施例,对本发明进行进一步详细说明。应当理解,此处所描述的具体实施例仅用以解释本发明,并不限定本发明。
一种基于能源控制器公变的台区停上电快速定位方法,包括以下步骤:
步骤1:根据特征电流式台区拓扑识别技术,配合带有特征电流发送和识别的智能感知设备,实现台区拓扑关系的准确识别;
步骤2:能源控制器公变对台区拓扑关系的识别记录归一化梳理,理清台区设备的父子关系,并生成一组或几组拓扑结果;
台区物理拓扑关系梳理是在能源控制器启动拓扑识别完成后或拓扑关系发生变化后梳理,并存储在能源控制器内,可在能源控制器任务执行压力比较小时梳理,减小能源控制器的运行负荷,台区拓扑结果梳理流程如图2所示。
步骤3:能源控制器公变在收到台区设备停电的上报信息后,将该停电设备在拓扑关系中的对应位置置位;
步骤4:重复步骤3,一直收集台区设备停电信息,直至收集完成或者到达一分钟的收集时长限值;
步骤5:根据已收集的台区设备停电信息,配合已知的台区物理设备拓扑关系,生成台区设备停电拓扑结果;
由于台区物理拓扑关系已提前梳理完毕,在接收到台区内设备节点停电的事件上报后,能源控制器所做的只是内存的置位操作,保证整个停电拓扑关系结果的梳理过程更加高效,台区停电设备快速定位流程如图3所示。
步骤6:根据停电拓扑关系,生成主节点停电事件,查找距离根节点拓扑距离最近的停电主节点设备,生成关键节点停电事件,事件通过能源控制器上报给局方主站。
关键节点的查找如图1所示,图中AT1和BT3为停电的关键节点。
上报给局方主站的主节点停电事件内容包括主节点停电时间以及停电的附属子节点个数占全部子节点个数的比例,关键节点停电事件内容包括停电的关键设备节点以及停电的附属子节点的停电时间。
上述实施例是对本发明的具体实施方式的说明,而非对本发明的限制,有关技术领域的技术人员在不脱离本发明的精神和范围的情况下,还可做出各种变换和变化以得到相对应的等同的技术方案,因此所有等同的技术方案均应归入本发明的专利保护范围。
