具体实施时,该系统主要安装在变电站出线、重要分支线和重要电力设备处,每条线路装1组(共3只)监测点,以实现这些点的远程监测和故障定位,当故障节点检测到故障发生条件,即向周边发射自身地址及故障原因,当其周边节点收到该数据后,先检查自身是否也存在于同一个故障线路上及具有相同的故障原因。如果存在同一线路及存在相同的故障原因。即把自己的地址,及故障原因添加进消息队列中再次发送,当采集器接收到该息信后,即把该信息通过GSM网络以短信或GPRS的方式发送给监控中心。该条信息会激活监控中心应用程序,向管理员提示故障线路,及故障原因。然后监控中心调用电网GIS平台故障点的拓扑分析功能。结合GIS图形上的故障指示器拓扑结构,判断故障点,故障点分析规则如下:从电源端开始查找,搜索到最后一个有故障的故障指示器,此故障指示器的供电范围(截至到各分支的第一个故障指示器,没有安装故障指示器的分支,整条分支都是故障范围)即故障线路区域。对故障信息,提供定位和重点着色功能,以不同的颜色显示故障区段和相关指示器设备,告知用户具体故障发生在哪一段线路上。用户使用定位功能,在地理模型信息上,实现对应故障信息在全网图上的定位与展示。In actual implementation, the system is mainly installed at substation outgoing lines, important branch lines, and important power equipment. Each line is equipped with a set of monitoring points (a total of 3) to realize remote monitoring and fault location of these points. When the faulty node detects When the fault condition occurs, it sends its own address and fault cause to the periphery. When the peripheral node receives the data, it first checks whether it exists on the same fault line and has the same fault cause. If there is the same line and the same cause of failure. That is to add its own address and the cause of the failure into the message queue and send it again. When the collector receives the information, it will send the information to the monitoring center through the GSM network in the form of SMS or GPRS. This message will activate the application program of the monitoring center, prompting the administrator of the faulty line and the cause of the fault. Then the monitoring center invokes the topology analysis function of the fault point of the power grid GIS platform. Combined with the fault indicator topology on the GIS graph, the fault point is judged. The fault point analysis rules are as follows: search from the power supply end, search for the last faulty fault indicator, and the power supply range of this fault indicator (up to each branch The first fault indicator, the branch without a fault indicator installed, the entire branch is the fault range), that is, the fault line area. For fault information, provide positioning and key coloring functions, display fault sections and related indicator devices in different colors, and inform users which section of the line the specific fault occurs on. The user uses the positioning function to realize the positioning and display of the corresponding fault information on the whole network map based on the geographical model information.
