摘　　要：输电线路自动故障诊断和故障定位实时发布系统(Fault Vista)实时监测电网运行状态,当电网发生故障时,将诊断结果和故障杆塔号自动展示于地理信息系统(GIS)之上,同时以短信方式通报给调度运行人员。介绍系统的主要功能模块,描述系统的特点和优势,提出非均匀线路故障定位算法和长线路混合型算法以提高故障定位的准确性。列举了几个典型故障实例,表明系统应用效果良好。The notification system of automated fault diagnosis and fault location for transmission lines（Fault Vista）monitors the electric power transmission network,and automatically displays the fault diagnosis result and fault location in terms of tower number on GIS（Geographic Information System）and notifies dispatchers via text messages when the fault occurs.We introduced the main functional modules of the system,described its features and advantages,proposed a new fault location method for nonhomogeneous lines and a hybrid method for long transmission lines to improve fault location accuracy. The paper concluded with a few field fault cases to demonstrate the effectiveness of Fault Vista.
