ABB PDD200A101｜Power Distribution And Drive Module｜

Function
Pulse driven output of thyristor
Receive CCM control board adjustment signals, output high-power trigger pulses, directly control the excitation rectifier bridge, and achieve generator excitation current closed-loop voltage regulation (AVR).
Real time monitoring and diagnosis of power circuit
Real time collection of rotor excitation current, power module temperature, rectifier bridge fault, and pulse loss signals, and real-time uploading of fault codes to the main control and upper monitoring.
Multiple hardware protections
Integrated excitation overcurrent, power component overheating, thyristor breakdown, and pulse loss lockout protection, cutting off the drive signal in the event of a fault to prevent damage to the excitation system and generator.
Multi channel bus communication
Onboard dual RS232/485 serial ports, multiple Ethernet ports, and data exchange with the PCD series control board in the entire excitation control cabinet through the internal bus of the backplane.
