1. Product Overview
ABB SYNCHROTACT6302 is a high-precision synchronization unit engineered for grid connection and parallel operation of generators, turbines, and large rotating machinery. It automatically matches key parameters (voltage, frequency, phase angle) between the equipment and the power grid, ensuring smooth, shock-free synchronization to avoid equipment damage and grid disturbances. Compliant with IEC 61000-6-2 (EMC) and IEEE 1547 (grid interconnection) standards, it’s a core component for power plants, industrial power systems (CHP), and renewable energy (solar/wind) plants.

3. Core Application Scenarios
3.1 Thermal/Hydro Power Plants
Synchronizes steam/hydro generators with the main grid during startup or load adjustment, preventing voltage/frequency fluctuations that affect grid stability.
Reduces mechanical stress on turbine-generator shafts by ensuring zero phase difference during connection.
Enables parallel operation of on-site generators (diesel/gas-fired) with the public grid, optimizing energy use (e.g., switching to grid power during low production hours).
Provides fast re-synchronization after grid outages to restore critical industrial loads (e.g., manufacturing lines, data centers) within seconds.
3.3 Renewable Energy Plants
Synchronizes solar/wind inverters or battery energy storage systems (BESS) with the grid, complying with IEEE 1547 standards for stable renewable energy integration.
Compensates for intermittent renewable energy output by adjusting synchronization timing to match grid demand.
4. Core Features
