Abstract :
This paper employs a quasi dynamic model for transient and long term analysis. The set of equations considered permits to calculate the solution by using the Newton-Raphson´s method. The simplicity of the model allows one to obtain some pieces of information required to take preventive control actions. A particular case of interest is the ramp load increase. For this sake, a real Brazilian system is employed, so the transient, long term and voltage collapse studies are carried out with all limits considered.
