Description
Product Overview
The SYN5302A (3BHB006716R0277) belongs to ABB SYNCHROTACT 5 series, a four-channel redundant automatic synchronizing controller designed for generator and busbar paralleling. It integrates two independent SYN5202 dual-channel synchronizing units inside one housing, delivering high security for breaker closing synchronization. It is commonly paired with ABB AC800M and System 800xA DCS, continuously measuring voltage, frequency and phase angle between generator and grid to calculate the optimal closing instant and avoid dangerous electrical transients during paralleling.

Key Features
- Quad Redundant Safety Architecture: Built with two independent dual-channel synchronizing circuits wired in series. If one channel fails, the second channel takes over automatically, maintaining paralleling protection without interruption.
- High Precision Paralleling Control: Real-time comparison of voltage, frequency and phase difference between two power sources, predicting breaker closing time for smooth generator grid connection.
- SynView PC Configuration: Parameter setting, trend recording, event log and diagnostic review via ABB SynView software.
- Comprehensive Protection Checks: Includes synchrocheck function to block breaker closure when out-of-tolerance conditions are detected.
- Rich Event & Fault Logging: Records synchronizing sequences, alarms and hardware faults for post-event analysis and troubleshooting.
- DCS Integration: Seamless interface with ABB System 800xA and AC800M controllers for power plant automation systems.
Applications
- Thermal / hydro / gas turbine generator automatic synchronizing
- Power plant busbar tie breaker paralleling
- Cogeneration and industrial on-site power stations
- Black start and standby generator grid connection
- Substation automatic synchronization control
Installation & Maintenance Notes
- Install inside control cabinet with proper surge protection for PT voltage input wiring.
- Separate AC voltage measurement cables from high-current power wiring to reduce EMI interference.
- Configure synchronizing threshold parameters and perform full function test before commissioning.
- Download event logs regularly during scheduled maintenance to inspect latent hardware or signal faults.
- Verify redundant channel switchover function in outage periods.
FAQ
Q: What is the difference between SYN5202 and SYN5302A? A: SYN5202 is single dual-channel synchronizing device. SYN5302A contains two SYN5202 units, forming 4-channel redundant design for higher safety critical generator paralleling.
Q: What software is used for SYN5302A parameter setup? A: ABB SynView software is used for configuration, monitoring, trending and fault diagnosis.
