1、 Basic Information
Complete model: PCD230A
Material Number: 3BHE022291R0101
Alias: PEC80-CCM Core Measurement Control Board
System: UNITROL 6000/UNITROL 6800 Generator Excitation System, AC800PEC Transmission Control System
Origin: Switzerland (ABB headquarters factory Baden), nameplate labeled Made in Switzerland
Original factory production status: not officially EOL discontinued, belonging to mature stock models; ABB is promoting the new generation of UNITOL 7000 supporting modules, but orders can still be placed from the original factory with longer lead times
2、 Core Function (Excitation System Core PLC Controller)
As the main control unit of the excitation regulator, responsible for closed-loop regulation of the entire unit:
High precision sampling of three-phase voltage/current (16 bit ADC, sampling rate 10kHz)
Excitation constant voltage, constant reactive power, constant power factor, PSS power system stability control
Complete set of protection logic operations for over excitation, under excitation, over-current, demagnetization, and abnormal frequency
Multiple communication interfaces: Ethernet, Profibus DP, Modbus, IEC61850 power station communication protocol
24VDC dual redundant power supply, single module power consumption ≤ 10W, 2kV electrical isolation between channels
Applicable: High power excitation cabinets for thermal power, hydropower, nuclear power, and gas turbine generator sets
3、 Physical dimensions&weight (original factory standard complete machine)
Dimensions (length x height x depth): 373 x 114 x 51 mm
Net weight: 2.4 kg
Original cardboard box packaging gross weight: approximately 2.7 kg
4、 Supply and substitution instructions
Original order lead time: 10-14 weeks; There is original brand new sealed inventory in stock on the market
