Experimental and Educational Platform for Operation Tests and Parameterization of Power System Regulators and Stabilizers

This paper presents the development and application of an experimental and educational platform for operation testing of synchronous machines and power system regulators. This platform is composed by an asynchronous motor, which simulates the primary machine, that is coupled to a synchronous generator shaft. The platform also includes a supervisory and control system, which acts on the parameterization of the regulators and drives the primary machine and generator’s excitation field. It is possible to carry out operation tests with the generator stator running in open circuit, stand-alone or connected to the grid, and to simulate disturbances in the system to observe the power system behavior and control performance in such cases. The main contribution of this research is a real platform for experimental validation of digital models of automatic voltage regulators, power system stabilizers and governors, consequently optimizing control design and parameterization. Regarding to the teaching in power system control, the differential of this platform is the unified approach of theory understanding with the comprehension of techniques for implementation of control and instrumentation in real systems, thus contributing to the improvement of student learning, professional formation and motivation for practical activities.
