| dc.description.abstract | Electric Power Systems (SEP) need to maintain their stability to ensure the supply of electrical energy continuously and within the required quality standards of minimum and maximum voltage and frequency levels. Stability maintenance is a rather complex task involving different categories of SEP stability studies, such as angular stability, voltage and frequency problems. Disturbances that can affect the stability of systems can be divided into serious and mild disorders, or large and small, which classify them as transient or dynamic characteristic disorders. There are numerous disorders that can occur in a SEP, the degree of severity of these disorders to the system, susceptible to the complexity of the arrangement and the control meshes (use of primary control regulators and / or secondary controls). Due to these analytical complexities: whether the system is stable or not to the data disturbances in the network; the use of computational tools is of great help for this categorization. The present Work of Conclusion of Course presents the use of ANAREDE and ANATEM softwares, aiming to point out the false operation of the system, in relation to the synchronism of the synchronous machines, that can occur in ANAREDE, because despite performing analysis of the power flows, returning the levels of system reactors and reporting overloads and decreases in the voltage levels in the bars, for example, it does not perform the non-linear analysis of the electromechanical stability, performed by ANATEM, in the face of various perturbations. | |
