基于轨迹监测的配电网作业安全保护研究
Research on safety protection of operation in distribution network based on trajectory monitoring
Safety protection in power grid operation is of great significance for reducing safety risk of operators and ensuring stable operation of power system. Taking into account of protection issues during the grid operation, this paper investigates the risk warning and protection method based on monitoring of operator movement trajectories, and discusses the Beidou-based operation trajectory tracking and risk warning method for long-distance and large-scale operation. By real-time monitoring the deviation and working time between the trajectory and the preset trajectory of operators, the risk warning is issued when large deviation or operation time-out happens. For complex indoor working conditions such as substations, trajectory tracking based on ultra-width band(UWB) positioning and YOLO v7are used to issue risk warning when deviation, high-risk area entering, or violation behavior is detected. Effectiveness of the proposed method in comprehensive operation process of distribution network is verified through experiments.
