摘　　要：以提升电网设备运行环境安全预警的实时性为目的,设计云平台集群部署下电网设备运行环境实时预警系统。应用层内的电网设备运行环境预警中心利用非线性状态分析的预警方法构建预警模型后,形成预警估计值,有效预测电网设备运行环境;为了提高预警的实时性,引入非线性算子计算估计值的相似度,完成电网设备运行环境实时预警。实验结果表明:该系统实时预警的电网故障概率与模拟曲线重合度较高,残差浮动范围小,抗干扰能力强,且提高了预警实时性和准确性。In order to improve the real-time security early warning of power grid equipment operation environment,a real-time early warning system of power grid equipment operation environment under cloud platform cluster deployment is designed.The power grid equipment operation environment early warning center in the application layer constructs the early warning model by using the early warning method of nonlinear state analysis,forms the early warning estimation value,and effectively predicts the power grid equipment operation environment.In order to improve the real-time performance of early warning,a nonlinear operator is introduced to calculate the similarity of estimated values to complete the real-time early warning of power grid equipment operation environment.The experiment results show that the system has high coincidence between power grid fault probability and simulation curve,small residual floating range,strong anti-interference ability,and improves the real-time and accuracy of early warning.
