ABB SYN5202 SYNCHROTACT 5 Automatic Dual-Channel Synchronizer

The ABB SYN5202 is a fully automatic dual-channel synchronizer designed for demanding power system applications. It performs voltage and frequency matching, issues closing commands to circuit breakers only under safe synchronous conditions, and includes built-in synchrocheck monitoring. The dual-channel architecture (with diverse hardware and software structures) significantly reduces the risk of asynchronous closing. It supports up to 7 different parameter sets, allowing one device to handle multiple paralleling points with varying requirements. Commissioning and monitoring are simplified via the front panel or SynView PC software.

• Diverse Dual-Channel Design: Two independent channels with different hardware/software structures connected in series for highest safety against incorrect paralleling.

• Automatic Synchronization: Includes voltage/frequency matcher and command generation for precise breaker closing.

• Synchrocheck Mode: Can operate purely as a synchrocheck for monitoring manual paralleling, including dead bus/dead line functionality.

• Multiple Parameter Sets: Up to 7 configurable sets selectable via digital inputs for different circuit breakers or conditions.

• Flexible Integration: Supports communication options such as Modbus, Profibus, LON, and IEC 61850.

• Advanced Diagnostics: Real-time displays, transient recorder, event logging, and parameter setting via SynView software.

• Robust & Compact: Plug-in casing with optional surface mounting, wide auxiliary voltage range, and strong EMC compliance.

• High Reliability: Proven in power plants and substations worldwide for generator-grid and line-line paralleling.

• Product Type: Automatic Dual-Channel Synchronizer / Synchrocheck

• Series: SYNCHROTACT 5

• Auxiliary Voltage: Wide range (typically 24–250 VDC / 100–230 VAC, model-dependent)

• Measuring Inputs: Voltage U1/U2 (nominal 50–130 V, higher via transformers); Frequency 16⅔ / 50 / 60 Hz

• Accuracy: High precision (phase angle typically ≤ ±0.5°; frequency difference ≤ 0.01 Hz)

• Paralleling Relays: Robust relay outputs for breaker commands

• Digital I/Os: Freely configurable inputs and outputs

• Communication: RS232 (SynView); optional fieldbus interfaces (Modbus, Profibus, LON, IEC 61850)

• Casing: Plug-in type (optional surface mounting)

• Protection Class: IP54 (front) / IP50 (rear) typical

• Operating Temperature: Industrial range (e.g., -10°C to +55°C)

• Mounting: DIN rail or panel

• Power generation plants (thermal, hydro, gas turbine)

• Generator synchronization to grid or other generators

• Substations and switchyards for busbar or line paralleling

• Industrial captive power plants and cogeneration systems

• High-safety redundant synchronization setups

• Retrofit projects in existing power infrastructure

Q: What is the difference between SYN5202 and SYN5201?A: SYN5201 is a single-channel automatic synchronizer; SYN5202 is a dual-channel version with diverse independent channels for higher safety.

Q: How does the dual-channel design enhance safety?A: Two differently structured independent channels operate in series, greatly minimizing the probability of incorrect paralleling.

Q: Can the SYN5202 be used for manual paralleling?A: Yes, it supports synchrocheck mode to monitor conditions and release commands for manual operations, including dead bus/line.

Q: How many different paralleling configurations does it support?A: Up to 7 parameter sets can be stored and selected, ideal for complex switchyards with multiple breakers.

Q: What software is used for configuration and monitoring?A: The SynView PC tool provides parameter setting, real-time visualization, transient recording, and event logging.

Q: What communication protocols are available?A: Optional Modbus, Profibus, LON, and IEC 61850 for seamless integration into DCS/SCADA systems.
