| Abstract: | Mathematical models of a capacitor voltage transformer (CVT) with quick saturati ng reactor for its various states,i.e.zero-load state,normal-loaded state,shor t circuit state of primary and short circuit state of secondary,are presented.Di gital simulation models of the CVT corresponding with various states using an ad equate digital integration method are developed.On the basis of the digital simu lation models a digital simulation of CVT on PC is conveniently realized and tra nsient characters of CVT are researched on PC according to the national standard (GB4703).Details are demonstrated with the aid of a numerical example.The resul ts show that the mathematical models and the digital simulation models are corre ct. |
