摘　　要：深入研究了智能配电系统的安全需求,对智能配电系统与传统信息系统的区别进行了详细的总结,并全面分析了智能配电系统设备层通信的脆弱性以及存在的安全隐患。在此基础上,从Modbus协议安全的角度出发,基于Hash函数提出了Modbus报文安全性解决方案,设计了Modbus安全认证协议。通过修改KB0系列控制与保护开关的源代码,在实物通信中证明了该方案的可行性与可靠性。基于安全性关键技术,初步建立了智能配电系统安全防护体系,对研究智能配电系统安全具有指导意义。This article studied the safety needs of the intelligent power distribution system,summarized the difference between the intelligent power distribution system and the traditional information system in detail,and thoroughly analyzed the vulnerability as well as the existing security risk of the mechanical floor of the intelligent power distribution system.Then starting from the Modbus protocol security,Modbus message security solutions based on Hash function were proposed and Modbus security authentication protocol was designed.Meanwhile,the foresaid plan was verified on account of the intelligent power distribution system which is constituted of control and protective switching devices.By modifying the source code of control and protective switching devices(KB0),the feasibility and reliability of the schemes were proved in the physical communication.Based on the security-critical technology,the safeguard system of the intelligent power distribution system has been preliminary established,which is of guiding significance to the study on the safety of the system.
