摘要：
The real-time identification of sampling data can avoid incorrect action of protection and monitoring device. It is difficult to distinguish abnormal sampling data and electric parameters in system failure for single sampling points. The existence of second derivative of electrical quantity in power system is proved firstly; the error between the adjacent remainder of Lagrange Linear Interpolation is deduced secondly; and the error threshold are given last. This method has the strong realtime processing capability and suitable for all kinds of relay protection and real-time systems such as measurement and control device.
