System Load Dynamics-Simulation Effects and Determination of Load Constants

Justification for using more realistic load models in stability studies than has been the practice heretofore is presented below. Examples are given which show that stability tests may be dramatically affected by load-voltage characteristics, or that more sophisticated models are necessary under conditions which preclude the usual composite load assumptions. In conclusion the paper states that system measurements are the most practical means of obtaining realistic load-voltage data for use in computer stability programs.
