基于GPS的无人值守变电站故障设备定位系统研究

The Research of GPS-Based Unmanned Substation Equipment Failure Positioning Systems

摘要: 无人值守变电站的快速发展，越发凸显出变电站中设备状态监测的重要性，本文提出了一种基于GPS卫星系统的无人值守变电站故障设备定位系统；介绍了该系统的功能、结构；着重分析了该系统定位原理。该系统采用GPS伪距差分定位实现了变电站设备定位功能，并通过有效采集变电站中各设备状态信息反馈到控制中心，从而实现故障设备的精确定位。

Abstract: The rapid development of unattended transformer substation highlights its importance of equip-ment condition monitoring. This paper proposed a faulty equipment positioning system in unat-tended transformer substation based on a GPS satellite system, introduced the system’s function, structure and focused on analyzing the system’s positioning principle. The system uses GPS pseu-dorange differential positioning to achieve the location of transformer substation’s equipment, and by feedback the effective collected information of each substation device status to the control center, enabling precise positioning of the failed device.
