北斗实时高精度定位服务在智能变电站中的应用

Application of Beidou Real-time High-precision Positioning Service in Smart Substation

针对当前智能变电站中现有定位方式在实际应用中存在定位精度低、内符合定位精度无法达到厘米级标准的问题,开展北斗实时高精度定位服务在智能变电站中的应用研究。通过智能变电站北斗地基选址与观测墩构建,增强北斗地基体系;为满足变电站巡检的位置精度要求,采集高精度无人机巡航定位路径;通过智能变电站人车巡检定位,保证人员与车辆的安全。通过实例分析证明,北斗实时高精度定位服务的应用可有效提高智能变电站的定位水平,将定位内符合精度控制在厘米级范围内。

In view of the problems of low positioning accuracy in the practical application of existing positioning methods in smart substations,and the positioning accuracy cannot reach the centimeter-level standard,the application research of Beidou real-time high-precision positioning service in smart substations is carried out.Smart substation Beidou foundation site selection and observation pier construction,enhance the Beidou foundation system;In order to meet the position accuracy requirements of substation inspection,the cruise positioning path of high-precision UAV was collected.Finally,the safety of personnel and vehicles is guaranteed through the inspection and positioning of intelligent substation.The example analysis proves that the application of Beidou real-time high-precision positioning service can effectively improve the positioning level of smart substation,and control the accuracy of in-positioning within the centimeter-level.
