Research on Transmission Delay Control and Emergency Response for Hydrological Information in Overseas Hydropower Stations
境外水电站水情信息传输延迟治理与应急响应研究

摘要

境外水电站选址多集中于热带山地区域，公网信号覆盖存在盲区，水情数据回传主要依托北斗卫星短 报文通道。但地形遮挡造成信号衰减，湿热工况加速器件老化，导致防汛调度决策与大坝安全应急响应均受 掣肘。围绕上述瓶颈，研究构建终端硬件迭代、站基设施适配改造、多信道冗余切换与分级应急响应协同推 进的技术体系，以期实现复杂工况下系统运行韧性同步增强。

Abstract

Overseas hydropower stations are mostly located in tropical mountainous areas, where public network signal coverage often has blind spots, and hydrological data transmission mainly relies on BeiDou satellite short-message channels. However, terrain obstruction causes signal attenuation, and hot and humid working conditions accelerate component aging, which restricts both flood control dispatching decisions and emergency response for dam safety. Focusing on these bottlenecks, this study constructs a technical system that coordinates terminal hardware iteration, station infrastructure adaptation and renovation, multi-channel redundancy switching, and graded emergency response, with the aim of synchronously enhancing system operation resilience under complex working conditions.
