电力二次系统中计算机技术,通信技术以及网络技术的迅猛发展,使得智能变电站生产控制业务系统以及调度数据网之间数据传输越来越频繁,因此,电力网络的可靠性,及时性以及安全性越来越重要。从智能变电站的安全区域划分以及安全防护两个方面阐述了智能变电站的安全防护的要求,重点对智能变电站的二次安全防护系统的方案进行了探讨。
The rapid development of computer technology, communication technology and network technology in secondary power system make data transmission between production control business system and dispatching data network of intelligent substations more and more frequent. Therefore, the reliability, timeliness and safety of power network more and more important. This paper elaborates the requirements of the safety protection of smart substations from two aspects of the safety zone division of the substation and safety protection of the intelligent substation. The scheme of the secondary safety protection system of the intelligent substation is emphatically discussed.
