IV. Working Principle
After power-on and self-inspection, the module collects key operating parameters of the generator through isolated acquisition circuits and locks the grid phase reference via the hardware PLL unit. The high-speed processor calculates excitation adjustment commands in real time according to parameter deviation, dynamically adjusts the output excitation current, and realizes closed-loop stabilization of generator voltage and reactive power. During grid-connected operation, the module continuously corrects phase deviation to maintain synchronous operation. Once a fault is detected, it immediately triggers protection actions, latches fault information and uploads data to the upper monitoring system to ensure system safety.
