雷电定位系统基于卫星授时技术实现时间同步。为分析时间同步攻击对雷电定位系统的影响,在剖析现有电力时间同步安全防护措施的基础上,论文首先构建了考虑恶意时间同步攻击的雷电定位模型。其次,引入泰勒算法进行定位求解。最后,结合佛山雷电定位系统基于蒙特卡洛模拟法进行了定位误差的反演实验。研究结果表明:雷电定位精度与时间同步攻击下探测站的时间偏移呈正相关关系;当中心站点时间偏离0.2μs时,探测网边界点定位误差较正常误差可达3.16倍,验证了时间同步攻击对雷电定位系统的影响。

A lightning location system realizes time synchronization based on satellite timing technology. In order to analyze the in-fluences of time synchronization attacks on the lightning location system, by analyzing the existing time synchronization security protection measures in the power industry, firstly, we constructed a lightning location model in which the malicious time synchronization attacks were taken into consideration. Secondly, we introduced the Taylor algorithm for location solution. Finally, based on the Monte Carlo simulation method...
