摘要
智能变电站远动通信的安全是电力系统的重要环节,TLS技术可以实现控制端与变电站之间安全连接的建立过程,但是完整的TLS通信连接过程步骤与耗时较多,本文对智能变电站远动通信中的TLS过程进行优化,将完整的TLS过程与精简的TLS过程综合配置,有效降低了TLS过程造成的通信延时情况,提高了智能变电站通信网络的时间性能。
The security of telecontrol communication of smart substation is an important part of power system. TLS technology can realize the secure connection between the control device and substation, but the complete TLS communication connection process is complex and time consuming. In this paper, the TLS process in smart substation telecontrol communication is optimized, and the complete TLS process and the simplified TLS process are integrated? so as to effectively reduce the communication delay caused by the TLS process and improve the time performance of the communication network in smart substation.
