English abstract:
This work presents the behaviour of the voltage control loop in a self-excited synchronous generator running in the dynamic regime. The voltage control loop plays an important role in choosing and adjusting the controlling closed-loop. The output regulator of this loop is a specific three-phased rectifier: in the synchronous generatorīs self-exciting phase the rectifier functions are an uncontrolled rectifier; after the phase nominal voltage is reached, the rectifier functions as a semi-controlled rectifier. The switch between the two functioning regimes is done without a pause. This work underlines the control loop performances in the dynamic regime for type P or PI rectifiers. The stability analysis was done following the simplified Nyquist criterion and hodographs. The analysis method can be used for other applications with minor modifications of the program.
