智能配电网的通信隔离方案研究

Research on scheme of smart distribution grid communication isolation

针对智能配电通信网中的信息安全以及信息的隔离问题,提出一种实现信息隔离的配电通信方案.该方案利用MPLS_VPN的QoS、流量工程机制以及不同VPN之间的信息隔离特性,可以实现变电站信息在网络中高速、安全地进行传输.在接入端,利用IPSec的加密、认证功能可以实现业务信息拥有严格的机密性.通过对配电网的仿真,可以看出此方案在电网通信中可以利用不同的VPN来实现关键信息与一般信息之间的隔离.本方案在传输信息时其隔离性较好,可以较好地提高配电网的通信安全.

Aiming at the information security and isolation question of smart distribution communication grid, this paper proposed a smart distribution communication scheme which can solve this information isolation question. This communication system in smart distribution bone network uses the QoS , traffic engineering mechanism and isolation technology of the MPLS_VPN technology, realizing that substation information could transmit speedily and safely in communication backbone network. At the access side, using the IPSec encryption and authentication functions can realine that the critical business information has a strict confidentiality. According to the simulation result of smart distribution communication grid, we can find that this scheme in the grid communication can use different VPNs to realize the isolation between the critical information and general information in the communication systems. This scheme can get a good isolation when transmiting information and can improve the communication security of smart distribution grid.
