摘　　要：为增强电网访问服务端对于电量信号的承载能力,避免访问风险,提出基于时间序列数据库的电网访问服务端风险预警方法。确定电量挖掘深度,计算电网负荷量的具体数值,完成基于时间序列数据库的电网负荷分析。选取电压、电流作为预警对象,并分别计算上述指标参量在越限与过载情况下的数值水平,实现新型电网访问服务端风险预警模型的设计与应用。实验结果表明,与多态不确定性评估方法相比,在时间序列数据库作用下,电网访问服务端对于电压、电流两类电量信号的承载能力明显增强,能够更好避免风险访问行为的出现。In order to enhance the carrying capacity of power grid access server for power signal and avoid access risk,a risk early warning method of power grid access server based on time series database is proposed.Determine the depth of power mining,calculate the specific value of power grid load,and complete the power grid load analysis based on time series database.The voltage and current are selected as the early warning objects,and the numerical levels of the above index parameters under out of limit and overload are calculated respectively,so as to realize the design and application of the new risk early warning model of power grid access server.The experimental results show that compared with the polymorphic uncertainty evaluation method,under the action of time series database,the carrying capacity of power grid access server for voltage and current signals is significantly enhanced,which can better avoid the occurrence of risk access behavior.
