| Abstract |
This paper proposes a starting and grid-synchronization control method for a salient-pole synchronous generator using a Voltage Source Converter (VSC)-based Static Frequency Converter (SFC). Unlike conventional thyristor-based SFCs, the VSC-based system offers precise PWM-based voltage and speed control, enabling self-commutation even in low-speed regions. The proposed control structure consists of a speed control loop and a phase angle controller, enabling stable generator startup and suppressing inrush current during synchronization. Simulation results demonstrate the improvement in transient current response by comparing cases before and after phase angle correction. Furthermore, the proposed method was validated through Hardware-in-the-loop simulation, confirming its effectiveness for real-time implementation. |
