随着电力系统的发展及其复杂性的增加，基本上是由于与其他生产中心的互连，引入新的控制系统技术的必要性。只有当从网络接收的数据快速准确地到达时，这些控制中心的效率才有可能。一个系统运行的基本任务是得到一个可靠、准确的真实的时间网络模型。在过去甚至在现在，通过使用系统控制和数据采集（SCADA）并经由状态估计器算法处理SCADA数据来获得真实的时间网络模型。今天的现实是不同的，智能电子设备（IED），数字故障记录器（DFR），相位测量单元（PMU）和继电器，收集了大量的数据，通过SCADA系统到达控制中心。因此，需要其他方法来验证和利用这些数据。
With the development of electric power systems and their increase of complexity, basically due to the interconnection to other production centres, impose the necessity of introduction of new control system techniques. The efficiency of these control centres is only possible if data received from network arrives quickly and with accuracy. The basic task of a system operation is to get a reliable and accurate real time network model. In the past and even in the present, the real time network model is obtained by the use of system control and data acquisition (SCADA) and processing of the SCADA data via state estimator algorithms. Today's reality is different, intelligent electronic devices (IEDs), digital fault recorders (DFRs), phase measurement units (PMUs) and relays, collects an enormous amount of data that arrives to control centres through SCADA system. So, other ways to validate and utilize this data are needed.
