Therefore, more 0 引言 attention should be paid to investigate data security vulnerabilities of real power systems and formulate 电力系统安全可靠运行是国民经济持续健康 corresponding defense mechanism during process of 发展的重要保障。因此，对电力系统运行状态进行 constructing secure smart grids. For this reason, basic 实时监控至关重要。通过对SCADA 系统实时采集 principles of fraudulent data and their impacts on power [1] 的量测数据进行滤波，电力系统状态估计 能够推 systems are firstly discussed. Secondly, according to feasible ways of constructing fraudulent data, their manipulation 断出表征电力系统实时运行状态的状态变量，为能 methods are classified into 2 categories: manipulating data 量管理系统做出潮流优化、电网实时建模及应急 collection and corrupting data communication. Thirdly,
