ABB SYNC HROTACT synchronous equipment product line
Module positioning
This product is a variant of ABB’s sixth generation synchronous device SYNC HROTACT 6, with the core function of achieving precise synchronous parallel operation between multiple generators or generator sets. It is not a regular controller or I/O module, but a dedicated synchronous detection and closing control device, widely used in scenarios such as power plants and hydropower stations.
■ Core functions
Simultaneous detection: Real time monitoring of the voltage amplitude, frequency, and phase angle difference between the unit to be connected and the bus (or another unit) to determine whether the parallel conditions are met.
Closing control: When the synchronous conditions are met, an automatic closing pulse is issued to close the circuit breaker and complete the parallel operation.
Multi parameter storage: Up to 7 sets of parameters can be stored, corresponding to 7 different parallel points. A single device can manage the synchronization of multiple circuit breakers.
Digital I/O: Digital input and output can be freely configured, and all I/O are electrically isolated.
Communication integration: Supports bus control systems such as MODBUS and Profibus, greatly reducing on-site wiring and auxiliary relays.
Frequency adaptation: The rated frequency supports 50 Hz, 60 Hz, and 16 2/3 Hz.
■ Safety and Standards
⊙ Complies with IEC 61508 SIL2 functional safety level
⊙ Compliant with IEC 61850 Ed.2 communication standard
Robust design, suitable for high reliability power generation scenarios
■ Typical applications
⊙ Parallel operation of generators in thermal power plants during the same period
The synchronous parallel operation of hydropower station generators (the main generators of the Three Gorges Dam are equipped with SYNC HROTACT synchronous devices)
Load sharing scenario where multiple generator sets operate in parallel
Upgrading projects that require the replacement of old SYNC HROTACT systems or contemporaneous devices from other vendors

■ Precautions for use
This module is a dedicated synchronous device and cannot replace ordinary DCS controllers or I/O modules.
When replacing, it is necessary to confirm that the model is completely identical (3BHB006715R0277/SYN5202-0277). Different variants have different parameter configurations and cannot be mixed.
This model has been discontinued, and the market is dominated by inventory and disassembled parts. It is recommended to prioritize confirming the reliability of spare parts sources and verifying the specific units and systems that are compatible when purchasing.
For applications involving SIL2 safety functions, debugging must be carried out by engineers with functional safety qualifications.
The parameter settings of the synchronization device (voltage difference, frequency difference, phase angle difference threshold) need to be set item by item according to the characteristics of the on-site generator and circuit breaker, and cannot be directly copied from other unit parameters.
