ABB HESG324442R11 (216VC62A) Excitation Control Board

Product Brief Description

The ABB HESG324442R11, also known as 216VC62A, is a generator excitation control board, the earlier hardware revision of HESG324442R12. It is a core control PCB for ABB synchronous generator excitation systems, responsible for closed-loop regulation of excitation current. Designed for power industry cabinet installation, the board features strong EMC resistance to work stably in high electromagnetic interference environments in power plants.

Product Functions

• Closed-loop adjustment of excitation current to stabilize generator terminal voltage
• Monitor generator operating parameters and perform reactive power control
• Switch between automatic excitation control mode and manual control mode
• Implement protection logic for over-excitation, under-excitation and voltage anomaly
• Receive voltage and current feedback signals and communicate with main excitation controller
• Built-in self-diagnosis function for hardware fault detection and alarm output

Application Scenarios

• Thermal power plant synchronous generator excitation control cabinets
• Hydropower station generator voltage regulation systems
• Industrial self-provided power plant and backup generator sets
• Power grid generator auxiliary control and protection system
• Offshore and marine generator excitation control equipment
