【摘要】：随着我国智能变电站推广和三网合一(站控层制造报文规范(manufacturing message specification,MMS)网络、过程层采样值(sampled measured value,SMV)、面向变电站事件的通用对象(generic object oriented substation event,GOOSE)网络)研究深入,采样值报文安全研究与应用也越来越重要与迫切。该文基于IEC 62351数据和通信安全标准,对采样值报文信息安全进行了研究与分析。通过在报文中添加时间域、循环冗余(cyclic redundancy check,CRC)校验及认证内容等方法对具体的采样值报文格式进行改造,给出了采样值安全风险对应处理机制,设计了服务器和客户端的交互实现流程,解决了SMV数据报文在传输过程中被非法篡改及重放攻击等问题。在现有智能变电站装置基础上研制了保护、测控和合并单元装置采样值模块,并应用于现场。
[Abstract]:With the promotion of intelligent substation in China and the integration of three networks (station control layer manufacturing message specification specification message) network. Process layer sampling values are sampled measured value SMVs. The research on generic object oriented substation event-Goosse network for substation events is advanced. The research and application of sampled-value message security is becoming more and more important and urgent. This paper is based on IEC 62351 data and communication security standards. The security of sampled message information is studied and analyzed. Cyclic redundancy check is cyclic redundancy by adding time domain to the message. CRC (CRC) verification and authentication methods are used to modify the format of sampled-value message. The corresponding mechanism of sampling value security risk is given and the interactive realization flow between server and client is designed. The problems such as illegal tampering and replay attack of SMV data packets during transmission are solved. Based on the existing intelligent substation devices, the sampling value module of protection, measurement, control and merging unit is developed. And applied to the field.
