电力系统跨安全防护区信息交互研究

Research on Information Exchange of Power System Security Protection Area

安全防护区是电力信息系统的安全防护方案,通过设置有效的分级安全防护,保证了电力系统整体的信息安全。现有的跨安全防护区信息交互以文本方式为单一手段,交互速度慢,无法满足日益增长的数据信息交互需求,因此迫切需要解决跨安全防护区的信息快速交互。文章在原有安全防护区架构设置的基础上,提出了基于网关的信息交互方案。采用二进制(正向)方式提供了更为先进的跨安全防护区信息交互,在不影响安全性能情况下,提高了跨安全区数据交互的整体性能。通过该方法的应用,提高了数据交换速度,经过长期稳定运行,证明该方法在不影响安全的前提下,有效地解决了传统跨安全区数据传输的效率问题。

Security protection area is a security protection program; it ensures the information security of the power system by setting effective security classification. The existing information exchange security protection area takes text method as the only approach, which can not meet the growing demand for data information exchange, Therefore, it is needed to solve the problem of trans-regional information exchange. Based on the framework of the original security protection area, an information exchange program based on gateway is proposed. That program provides more advanced information exchange security protection area by binary, scheme in order to improve the overall performance without affecting the secu- rity performance. Through the application of this method, the data exchange speed is improved. After a long-term stable operation, it proves that it effectively solves the problem of poor efficiency of traditional trans-regional data transmission without affecting the safety.
