Software in Labview to automate tests on Synchronous Generators.

Abstract

For efficient operation of electric generators in power systems, it is necessary to validate and estimate machine parameters. Through these parameters, time-domain simulations can be performed to predict their behavior during transients and make correct decisions, such as load relief, calibration of protection schemes, and stability issue corrections. These parameters are not always provided by the manufacturer and may change over the generator's lifetime. The lack of accurate parameters can lead to inconsistent simulations, negatively impacting projects and even causing unforeseen blackouts. The need to estimate parameters becomes even more relevant due to the inclusion of distributed energy sources, which use small-scale synchronous generators, and wind turbines, which use induction generators. The objective of this work is to develop a Labview program to automate this process. The project is divided into four stages. In the first stage, a comprehensive theoretical study of electrical machine tests will be conducted. In the second stage, practical laboratory tests will be performed, automating the data collection using Labview. The third stage involves applying the laboratory tests to determine the parameters of the synchronous generator and recording the results in a database. Finally, in the fourth stage, the results will be refined. The tests will be conducted in a small power system set up in the electrical machines laboratory of the Department of Electrical Engineering and Computer Science at the University of São Paulo.
