ABB SYN5302A, 3BHB006716R0277 (SYNCHROTACT 5) Characteristics

Manufacturer: ABB

Model: SYN5302A

Part Number: 3BHB006716R0277

Device Type: Dual-channel auto-synchronization module for AC 800M controller under SYNCHROTACT 5 series

Adopts dual-channel redundant hardware architecture, equipped with two independent 3-phase VT input channels to sample voltage signals from grid and generator.

Performs real-time acquisition of voltage, frequency and phase angle, and delivers high-precision phase measurement to calculate slip value.

Synchronization precision: phase angle error ≤ ±1 electrical degree; voltage difference and frequency difference limits can be flexibly configured.

Frequency measuring range: 15~75Hz, compatible with both 50Hz and 60Hz power grids.

Voltage input: supports VT secondary voltage configuration, typical measuring range 0~150V AC.

Offers three operation modes: automatic synchronization, manual synchronization and remote synchronization.

Digital logic outputs cover SYNC OK status signal, circuit breaker closing instruction and fault alarm signals.

Comprehensive built-in monitoring functions, including overvoltage, undervoltage, overfrequency, underfrequency and phase sequence error detection to prevent false breaker closing.

Interconnects with ABB AC800M controller through backplane bus; parameter configuration realized via Control Builder M engineering tool.

Optional communication interfaces: IEC 61850, Modbus, Profibus for remote monitoring and diagnostic access.

Power supply is supplied by AC800M base unit backplane.

Protection rating: IP20.

Typical applications: generator paralleling and busbar synchronization for power stations and combined heat and power plants.

1. Pre-installation Inspection & Safety Preparation

Confirm the part number SYN5302A / 3BHB006716R0277, and inspect the module casing and connectors for physical damage or oxidation.

Implement LOTO lockout-tagout procedure and de-energize all control circuits and VT secondary sampling circuits.

Check the installation environment: temperature range 0~60℃, good ventilation, away from high-temperature equipment and strong EMI interference sources; keep away from humid, dusty and corrosive environments.

Prepare necessary tools and materials: wiring schematic, multimeter, SynView configuration software, communication cables and shielded wires.

2. Mechanical Installation

Install TU531 / TU532 terminal base onto the DIN rail inside the control cabinet.

Insert the SYN5302A module into the terminal unit and secure it in place.

Reserve sufficient heat dissipation space: ≥5cm clearance on left and right sides, ≥8cm on the top, ≥3cm at the rear; maintain horizontal installation.

3. Wiring Work

Route dual three-phase VT sampling cables: connect grid voltage to Channel 1 and generator voltage to Channel 2; deploy double-shielded cables with single-point earthing.

Wire logic output terminals including SYNC OK status signal, circuit breaker closing command and fault alarm output.

Run communication cables for optional protocols (IEC61850, Modbus, Profibus).

The module gets power from the AC800M backplane; verify reliable bus contact.

Maintain a minimum 20cm separation between sampling cables and control cables to minimize interference.

Before powering on, fully inspect all wiring to rule out short circuits, polarity errors and loose terminals.

4. Power-on & Hardware Self-test

Restore power supply after wiring verification.

Monitor front-panel LED indicators and ensure no hardware fault alarms during module startup self-test.

Retrieve raw measurement data through SynView or front panel: voltage, frequency and phase values of two VT inputs to validate sampling precision.

Check phase sequence for both grid and generator voltage inputs; a phase sequence fault should trigger the blocking alarm.

5. Parameter Configuration

Complete configuration via SynView PC software or local front-panel keypad.

Set fundamental system parameters: rated frequency (50Hz / 60Hz), VT secondary rated voltage and breaker closing advance time.

Define synchronizing thresholds: permissible voltage difference, frequency difference and maximum allowable phase angle deviation.

Set supervision protection limits for overvoltage, undervoltage, overfrequency and underfrequency.

Configure communication parameters such as IP address, station address and baud rate in accordance with system requirements.

Download the parameter project to SYN5302A and save a backup copy of the configuration file.

6. Offline Simulation Commissioning (No Live Closing)

Feed simulated three-phase voltage signals into the two VT input channels for dry-run testing.

Validate three operation modes: automatic synchronizing, manual synchronizing and remote synchronizing.

Confirm the SYNC OK signal is only activated when all synchronizing criteria are fulfilled.

Test blocking logic: the closing command shall be inhibited if voltage, frequency or phase exceeds preset thresholds.

Simulate fault conditions such as signal loss, incorrect phase sequence and overvoltage to verify proper alarm activation.

Test communication transmission to ensure real-time status and measured values can be uploaded to AC800M and SCADA system.

7. On-site Live Test & Functional Verification

Carry out live paralleling test with generator at no-load status while keeping the breaker open for the first trial.

Monitor real-time slip speed, phase angle and voltage difference curves; verify synchronizing prediction and advance closing logic.

Perform supervised trial closing; confirm the breaker closing pulse is released at the correct advance time once all synchronizing conditions are met.

Verify dual-channel redundancy, fault detection and cross-monitoring functions of the two independent channels.

Validate interlock logic between SYN5302A and breaker control circuit.

8. Final Acceptance & Documentation

Document all test data, alarm logs and synchronizing curves.

Archive the final configuration file as backup.

Confirm protection blocking, alarm signals and communication functions operate as designed.

Complete the commissioning report and hand over documents to the on-site operation team.
