ABB SYN5201‑2277 3BHB006714R0277 SYNCHROTACT5
Product Overview
ABB SYN5201‑2277 (Part No. 3BHB006714R0277) belongs to the SYNCHROTACT5 series. It is a single‑channel automatic synchronizing device with integrated frequency and voltage regulation outputs. It is applied for grid connection of synchronous generators and parallel‑switching operations between synchronous lines.
The SYN5201‑2277 can perform fully‑automatic synchronizing independently. It can also function as a monitoring and verification unit for manual grid‑connection, to avoid grid surges and unit damages caused by non‑synchronous closing. It adapts to 50Hz and 60Hz power frequency systems, meeting synchronizing control requirements for power stations and industrial self‑generation scenarios. It supports parameter configuration and status reading via the supporting PC debugging tool SynView.

Core Functional Advantages
The SYN5201‑2277 is equipped with complete automatic frequency and voltage regulation logic. It outputs speed governing and voltage regulation pulse signals to governors and voltage regulators, automatically matching the voltage and frequency of the incoming generator side to the grid system side without continuous manual operation.
It features advanced closing angle calculation. The device outputs closing commands in advance according to the inherent operating time of circuit breakers, ensuring precise contact closure within the valid synchronizing window.
Built‑in Synchrocheck synchronizing monitoring logic continuously verifies phase angle, voltage and frequency conditions even under fully automatic mode. Closing output will be locked immediately if synchronizing conditions are not met, effectively eliminating risks of misoperation and abnormal grid connection.
The device supports multi‑group parameter storage. Independent calibrated parameters can be saved for different grid connection points, avoiding repeated parameter configuration during on-site working condition switching.
Matched with the professional SynView commissioning software, it supports real-time data monitoring and event alarm record query, greatly simplifying on-site commissioning and equipment fault troubleshooting processes.
Equipped with multiple standard communication interfaces, the device can be seamlessly connected to power station monitoring systems to realize remote status monitoring, alarm data uploading and remote parameter reading and writing.
Product Features
Adopts integral metal shell and standard panel mounting structure, perfectly compatible with conventional control cabinet openings.
Independent hardware measurement circuits and multi-dimensional abnormal judgment algorithms are embedded to effectively suppress detection misjudgments caused by harmonic interference and voltage fluctuation.
Supports dead-bus and dead-line closing logic, adapting to island power generation and standby power supply switching working conditions.
All input and output terminals adopt optoelectronic isolation design, significantly improving anti-electromagnetic interference capability in complex industrial environments.
Built-in local LCD screen and physical keys support independent on-site parameter viewing and manual operation without upper computer equipment.
Dedicated LED indicator lights intuitively display equipment status including fault alarm, system ready and synchronizing condition satisfaction, facilitating rapid on-site operation and maintenance judgment.
Supports parameter password protection function to prevent unauthorized modification of core synchronizing calibration parameters.

Comparison of Products from the Same Brand
SYN5201‑2277 is a single‑channel automatic synchronizer with built‑in frequency and voltage regulation outputs. It fits medium‑and‑small‑sized single‑unit grid‑connection projects with moderate cost and provides no hardware redundant channels.
SYN5200: Designed only for synchrocheck function without automatic frequency‑voltage regulation outputs. Suitable for points where only blocking of manual closing is required.
SYN5202: Equipped with two independent internal hardware channels in a dual‑channel series architecture. One channel serves for synchrocheck. It is intended for power plants with higher safety‑level requirements and delivers better hardware redundancy than SYN5201‑2277.
SYN5302: Fully‑redundant four‑channel configuration integrating two SYN5202 units. Applied for large critical generating units with bumpless switch‑over upon faults and higher overall cost.
SYN5100: Simplified synchrocheck unit without communication ports or automatic regulation outputs for reduced‑function applications.
SYN5500: Auxiliary expansion unit for multiple paralleling point extension, used in combination with main synchronizing devices.
FAQ
Q: What is the relationship between SYN5201‑2277 and 3BHB006714R0277?A: SYN5201‑2277 is the product model while 3BHB006714R0277 is the part number. Both refer to the same SYNCHROTACT5 synchronizing device. Either reference can be used for order confirmation.
Q: Can SYN5201‑2277 directly drive the circuit‑breaker closing coil?A: Its outputs are relay contact signals rated at 3A. Direct driving of closing coils is generally not recommended. Intermediate relays shall be adopted for transition to prevent contact damage caused by heavy current.
Q: Is dual‑channel redundant grid‑connection achievable with SYN5201‑2277?A: The unit adopts a single‑channel hardware design with no second independent measuring channel. For redundant solutions, please select SYN5202 or SYN5302.
Q: Is hardware replacement required for SYN5201‑2277 between 50Hz and 60Hz units on‑site?A: The hardware is universal. Frequency switching between 50Hz and 60Hz is completed via software parameter setting, no hardware modification is needed.
Q: What information shall be additionally confirmed during procurement?A: Confirm part number 3BHB006714R0277, system frequency, auxiliary power supply specification, panel mounting cut‑out dimension and communication interface requirements.
