Resumo
The paper presents a methodology of analysis for radial power systems using quadripoles for the components repre-sentation. Three-phase elements can be represented this way if they can be considered symmetric and symmetrical components transformations are used in order to work with modal quantities instead of the phase ones. The application of the method is presented using several examples derived from real power systems, allowing interesting studies as voltage stability, reactive compensation, P-Q and P-V curves drawing, voltage variation and reactive power flow, among others. It is shown that the proposed tool demands substantially less computational effort, being, thus, very attractive to evaluate disturbances.
