光伏发电系统IEC 61850的通信安全性研究

Research on Communication Security of Photovoltaic Power Generation System IEC 61850

当前IEC 61850标准主要应用于变电站领域,在微电网领域应用很少,而在微电网中,分布式能源设备与变电站之间的通信缺乏统一的通信标准。为了提高微电网通信的安全性,解决不同厂商设备之间的互操作性问题,根据IEC 61850 ed2.0标准建模规范以及通信数据在微电网中的应用特点,以微电网中的光伏发电单元为例,提出了一种基于IEC 61850的微电网数据通信模型。对IEC 61850通信过程进行了安全性测试,并针对其通信过程中可能面临的风险,提出了基于SHA 256和RSA防御算法的安全通信机制。

The current IEC 61850 series of standards are mainly used in the field of substations,but they are rarely used in the field of microgrids,and the communication between distributed energy equipment and substations in microgrids lacks a unified communication standard.In order to improve the security of microgrid communication and solve the interoperability problem between devices manufactured by different manufacturers,this paper is based on the IEC 61850 ed2.0 standard modeling specification and the application characteristics of real-time data in microgrid,taking the photovoltaic power generation unit as an example,and a communication model based on IEC 61850 microgrid data is proposed.The related experiments are designed to test the security of IEC 61850 communication process,and a secure communication mechanism based on SHA 256 and RSA defense algorithms is proposed for the possible risks in IEC 61850 communication process.
