随着我国电力市场的不断发展,变电站自动化远程通信系统的通信效率已经成为变电站工作效率的高级指标,变电站自动化通信安全体系的建设是有效保障电力调度控制系统及其网络信息安全的关键,为了免除信息不被竞争对手窃取利用,有效保障电力调度控制系统及其网络的信息安全,实现远程通信的保密是变电站自动化通信安全体系所必须解决的问题。主要从变电站自动化远程通信安全体系进行探索,以找到实现变电站自动化远程通信安全体系升级的建设依据。 With the continuous development of power market in our country, the communication efficiency of the automation system of substation automation has become a high-level index of substation efficiency. The construction of substation automation communication security system is the key to effectively guarantee the power dispatching control system and its network information security. Information is not steal and utilize by the competitor, effectively guarantee the information security of power dispatching control system and its network, and realize the confidentiality of remote communication is a problem which must be solved in the automation communication security system of substation. Mainly from the substation automation telecommunications security system to explore in order to find the realization of substation automation telecommunications security system upgrade basis.
