MODELS: A new simulation tool in the emtp

MODELS is an autonomous general-purpose simulation program recently interfaced to two versions of the Electromagnetic Transients Program (EMTP). This interfacing enables the description of components that could not be represented easily until now using the electrical elements of the EMTP and the set of control blocks available in its TACS (Transient Analysis of Control Systems) section. This paper evaluates the usage of MODELS in the EMTP by stressing the differences in approach and use as compared to TACS. An application example is provided and discussed.
