摘要

This paper elucidates the closed loop structure of 'Load-System' and the characteristics of random signals in power system, and presents the minimum cross-correlation function method, an on-line identification method for static load modeling. This method is essentially different from the current least squares fitting method in the main idea, and is suitable for -the static load modeling under the normal operating conditions with low noise-to-signal ratio. The simulation and field data modeling of this method are carried out and the effects, of this method are also compared with the least squares fitting method.
