Excitation Processing Unit Characteristics: As the core of the excitation system, it is responsible for regulating the excitation current, stabilizing the terminal voltage, controlling reactive power, and improving dynamic stability of the synchronous generator/motor. Typical applications include thermal power, hydropower, nuclear power, and industrial motor excitation control (such as rolling mills and electric furnaces).

　　Excitation Control: Precisely adjusts the generator rotor excitation current through a PID algorithm to stabilize the terminal voltage, control reactive power, and improve the dynamic stability of the power system.

　　Pulse Trigger: Integrates a pulse trigger board (PTB) function to generate thyristor/IGBT trigger signals, control the rectifier bridge output, and ensure stable operation of the excitation power unit.

　　Protection and Monitoring: Real-time monitoring of parameters such as voltage, current, and temperature; supports overvoltage/undervoltage/overcurrent protection, over-temperature alarm, insulation fault detection, and fault diagnosis.
