This work aims to analyze the dynamic performance of a synchronous generator and its controls in a distributed generation system, as well as evaluate the impacts of its operation when connected to the distribution grid, using for this task the ATPDraw interface/tool of software ATP. Within this context, it is firstly necessary to obtain suitable models to represent the synchronous machine control systems (voltage regulator, speed governor and stabilizer system) in ATPDraw. Furthermore, for stability analysis, it is developed a mathematical technique to calculate the machine power angle which is represented in ATPDraw by a device (icon). The adjustments of voltage and speed control system parameters are performed by some adopted procedures which are verified using two electric systems: the first one with a synchronous generator connected to the distribution grid; and the second with three distinct generators forming a multimachine system. In these systems some disturbances are applied such as load shedding and short-circuit to accomplish the studies. Finally, with the previous results, it is carried out some dynamic performance studies of a synchronous generator of an independent producer connected to a distribution grid so as to assess aspects of power quality (voltage magnitude), stability and to evaluate the influence of machine controls during the system response for a given load shedding.
