IV. Working Principle
After power-on and self-inspection, the module collects core operating parameters including generator terminal voltage, excitation current, stator current and grid frequency through isolated acquisition circuits, and locks the grid reference phase via the hardware PLL unit. The high-speed processor calculates excitation adjustment commands in real time through closed-loop PID algorithm according to parameter deviation, and outputs control signals to the rear excitation power unit to dynamically adjust excitation current and stabilize generator voltage and reactive power.
Under grid-connected conditions, the hardware phase-locked circuit automatically corrects excitation parameters to ensure synchronous consistency between the generator and the grid, realizing stable and disturbance-free grid-connected operation. For load fluctuation and grid disturbance, the module responds within 100μs to execute dynamic forced excitation and limit excitation, suppressing unit oscillation and voltage drift.
The module monitors operating status in real time. Once excitation abnormality, parameter over-limit or phase desynchronization is detected, it immediately triggers protection logic, latches fault codes, records operation logs, and outputs alarm and interlock signals to complete de-excitation and shutdown protection. All data is uploaded to the upper system for visual operation, maintenance and data archiving.

3. Distributed power generation system of industrial self-provided power stations for isolated/grid-connected excitation control and power quality stabilization.
4. Power grid power quality optimization for voltage and reactive power balance adjustment and grid fluctuation suppression.
5. Technical renovation and in-situ replacement of old ABB AC800PEC excitation systems to reduce transformation costs and downtime.
