摘　　要：数据采集与监视控制系统,是智能电网的重要组成部分,是保障电力系统通信正常运行的基础。随着电力系统中计算机网络技术的广泛应用,使SCADA系统更加依赖信息系统和远程通信网络,更令网络安全威胁迅速增长。针对其网络安全的评估问题,提出了一种防御图结合证据网络推理的评估模型,以减少评估过程中的不确定性。通过算例分析,验证了该方法的有效性。Supervisory control and data acquisition system, is a smart grid is an important part of power com- munication system, is the guarantee of the basis for the normal operation of. With the development of power system in the broad application of computer network technology, SCADA system is more dependent on the information system and the remote communication network, the network security threats grow rapidly. In view of the networksecurity assessment of the problem, put forward a kind of defense of network evaluation model combining evidence reasoning, in order to reduce the uncertainty assessment process of. Through the example analysis, proved the validity of the approach.
