摘　　要：SCADA系统性能雪崩试验至关重要,但构建恰当的SCADA系统性能雪崩数据模型异常困难。文章在分析电力系统正常与故障时变电站自动化系统数据流特点的基础上,提出利用电力系统分析综合程序(PSASP)仿真模拟变电站复杂多重故障产生的上传遥测量,依照变电站自动化系统已配置的遥信数据库,推算该故障条件下可能产生的遥信量,再结合其他相关因素共同建立相应参考数据雪崩模型的工程方法。该模型构建方法可推广至调度自动化主站参考数据模型建立。Avalanche test is essential for testing SCADA system performance however, to build an appropriate avalanche data model is extremely difficult. Based on the analysis of power system under normal and breakdown condition with respect to the data flow of substation automation system, the authors propose using power system analysis software（PSASP） to simulate the uploaded remote measurement of substation under various complex and faulty conditions, estimating the possible telesignals generated under these faulty conditions with reference to the configured telesignal database of the substation automation system, and lastly, building corresponding reference data avalanche model considering the other related reasons. The model construction method can be extended to the reference data model construction of the dispatching automation master.
