基于异常数据溢出的电力调度系统监测预警的研究

Research on monitoring and warning of power dispatching system based on abnormal data overflow

电力调度系统存在时空故障样本数据,导致电力调度系统中异常数据溢出控制能力较差、监测预警精度较低,为此提出基于异常数据溢出的电力调度系统监测预警方法。通过采集电力调度系统的监测数据,获取异常数据溢出的负荷水平特征量,结合配电设备的工况特征进行时空故障样本数据处理。采用模糊监测方法,对电力调度系统的异常数据进行溢出控制,通过确定权限阈值,设置电力调度系统监测预警等级,从而构建预警模型,完成电力调度系统监测预警。仿真结果表明,该方法的电力调度系统监测预警精度较高,对异常数据溢出控制能力较好。

Due to the existence of time⁃space fault sample data in power dispatching system,the control ability of abnormal data overflow is poor,and the monitoring and early warning accuracy is low.Therefore,a monitoring and early warning method based on abnormal data overflow is proposed.By collecting the monitoring data of the power dispatching system,obtaining the load level characteristic quantity of the abnormal data overflow,processing the time and space fault sample data combined with the working condition characteristics of the power distribution equipment.Adopting the fuzzy monitoring method,controlling the abnormal data overflow of the power dispatching system,setting the monitoring and early warning level of the power dispatching system by determining the authority threshold,so as to build the early warning model,complete the monitoring and early warning of power dispatching system.The simulation results show that the monitoring and early warning accuracy of this method is high,and the ability of abnormal data overflow control is good.
