随着经济社会的发展,电力系统在生活中的作用越来越重要,智能电网对电力系统的安全也提出了更高的要求,而目前电力系统的结构还存在一些安全隐患,使电力通信系统的安全受到了威胁。论文分析了目前的电力通信系统的结构,结合安全隔离网闸技术,提出了一种基于正向隔离网闸技术的电力系统通信网络架构,这种架构能够有效地阻断外部网络对电力系统的威胁,保证了电力系统的安全。 With economic and social development, the power system plays an increasingly important role in daily life. The smart grid also places higher requirements on the safety of the power system. However, there are still some potential safety problems in the structure of the power system, which makes the power communication system The security is under threat. This paper analyzes the structure of the current power communication system, combined with the technology of security isolation gatekeeper, proposes a power system communication network architecture based on the forward isolation gatekeeper technology, which can effectively block the external network from affecting the power system Threat, to ensure the safety of the power system.
