The ABB GCD207B101 is a high-performance excitation power module,part number 3BHE024642R0101.The following are its detailed product details:
Product Positioning:An excitation power module specifically designed for medium-to-high power synchronous generators(1MW-10MW),serving as the core power source for the generator excitation system.
Features
Precise Regulation:Employs a digital PID control algorithm,achieving voltage regulation accuracy≤±0.5%.It responds to load changes within 100ms,adjusting the excitation current to stabilize the generator terminal voltage.
High Integration:Integrates the rectifier bridge,control board,and protection circuit into a single unit,eliminating the need for separate rectifier and control cabinets,reducing wiring complexity,and facilitating on-site installation and commissioning.Supports Modbus RTU protocol for remote monitoring.
Comprehensive Protection:Features five built-in protection functions:overcurrent,overvoltage,overheat,phase loss,and short circuit.When the module temperature exceeds 55℃,the built-in fan automatically speeds up;an alarm sounds at 65℃;and the unit shuts down immediately at 70℃.
Durable and robust:IP21 protection rating,resistant to dripping water and solid foreign objects.Internally uses imported high-power IGBTs with low conduction loss,low heat generation,and a service life of over 10 years.Stable operation is possible in environments ranging from-10℃to+55℃.
Technical Parameters
Input Voltage:Depends on specific application and configuration.
Output:Provides stable excitation current output for the generator excitation circuit.
Communication Interface:RS485 interface,supports Modbus RTU protocol.
Dimensions and Weight:Specific dimensions and weight are not explicitly mentioned,but generally a compact design for easy installation.
