ABB 3BHB001337R0002ABB Order Code 3BHB001337R0002
ABB UNS 0869A-P V2 3BHB001337R0001 Power System Stabilizer (PSS) Control Board for Generator Static Excitation Systems Core Function This dedicated PCB module is a critical power system stabilizer unit for ABB UNITROL series generator excitation control platforms. It dampens low-frequency power oscillations between synchronous generators and grid networks by modulating excitation voltage dynamically. It collects real-time generator speed, active power, and terminal voltage analog signals, executes PSS algorithm calculations, and outputs corrective regulation signals to the main excitation regulator to suppress grid swing, prevent generator out-of-sync trips, and boost power grid transient stability. It integrates galvanic signal isolation, hardware fault self-test, RS485 Modbus communicati
