A power amplifier system for testing of distance relay operating characteristic
Marçal, Rui; Rodrigues, Ricardo; Fortunato, Carlos; Martins, L. Sousa; Pires, V. FernãoThis paper describes a power amplifier system for testing of distance relay operating characteristic. This power amplifier is based on two three phase inverters with a neutral wire. The output power currents and voltages are controlled by a sliding mode controller. A developed matlab/simulink digital simulator generates the test signals. This test signals are converted in current and voltage references using a ...
