摘要
当前,配电网分布式控制身份认证安全系统多采用区块链技术与生物特征识别技术,但这两种技术易受到设备地理信息偏差性的影响,使系统的认证效率降低。为此,提出基于北斗卫星的配电网分布式身份认证系统。参照系统的基本功能和总体架构,设计了集成通信板卡和负反馈电路,从而为系统提供硬件支持。利用北斗卫星定位技术捕获运维设备的中频信号,通过计算信号的多普勒频移对地理信息进行修正,结合数据解析和数字身份管理模块完成身份安全认证系统的设计。系统调试对比结果表明,所提系统的证书处理耗时均保持在20 ms之内,平均时延显著低于对比系统。所提系统具有更高的认证效率。
Currently,the distributed control identity authentication security system for distribution grid mostly adopts blockchain technology and biometric identification technology,but these two technologies are susceptible to the influence of device geographic information deviation,which reduces the authentication efficiency of the system.For this reason,a distributed identity authentication system for distribution grid based on BeiDou satellite is proposed.With reference to the basic functions and overall architecture of the system,an integrated communication board and negative feedback circuit are designed to provide hardware support for the system.BeiDou satellite positioning technology is utilized to capture the intermediate frequency signals of the operation and maintenance equipment,and the geographic information is corrected by calculating the Doppler shift of the signals,which is combined with the data parsing and digital identity management module to complete the design of the identity security authentication system.The debugging and comparison results of the system show that the certificate processing time of the proposed system is kept within 20 ms,and the average delay is significantly lower than that of the comparison system.The proposed system has higher authentication efficiency.
