随着经济的高速发展,我国电网容量越来越大、结构亦趋复杂,传统的电网监控、调度管理模式初步向数字化电网过渡。在过去的几年,各级电网公司已经初步建成覆盖全区域的IP宽带数据骨干网络,满足了数字化电网生产管理的基本需求。随着区域经济的飞速发展和“十一五”规划的要求,有数量众多的厂站业务准备通过数据网络接入。不过,电网数字化带来的一个问题是随着电网二次业务通信方式的网络化,也带来的巨大的安全风险,
With the rapid economic development, China’s power grid capacity is more and more large, the structure also tends to be complex, the traditional power grid monitoring and dispatching management mode to the digital power grid transition. In the past few years, the power grid companies at all levels have initially built a backbone network of IP broadband data covering the entire region, meeting the basic requirements of digital power grid production management. With the rapid development of regional economy and the requirements of the “Eleventh Five-Year Plan”, a large number of plant sites are ready to be accessed through the data network. However, one of the problems brought about by the digitization of the power grid is that with the networking of the secondary service communication mode of the power grid, there is also a huge security risk.
