III. Main Functional Characteristics

1. Precise Load Distribution (Load Sharing)

Current sharing control: Precisely adjust the active power output of each generator in parallel operation to ensure load distribution is even and eliminate circulating current, prolonging the lifespan of the generators.

Control modes: Supports two modes: Isochronous (no difference) and Droop (with difference).

Isochronous mode: Used for single-unit operation or isolated grid, maintaining constant speed/frequency.

Droop mode: Used for parallel operation of multiple generators, achieving stable load distribution through the speed drop characteristic.

2. Fully Automatic Synchronization and Grid Connection (Synchronization)

Four-way synchronization: Automatically detect the voltage, frequency, phase, and sequence of the generator to be connected to the grid (or bus).

Real-time adjustment: Real-time adjust the speed and voltage of the generator to be connected to ensure synchronization.

Zero-impact grid connection: Issue a closing command at the moment when the conditions are perfectly matched, achieving zero-impact grid connection and protecting the generator and the grid.

3. Advanced Control and Protection

Voltage matching: Linkage adjustment of the automatic voltage regulator (AVR) to ensure consistent grid voltage.

Frequency fine-tuning: Provide precise frequency bias control to optimize grid stability.

Fault safety: Immediately lock out the closing and issue an alarm in case of synchronization failure, voltage anomaly, or frequency over-limit.

Remote monitoring: Through RS-232/422 interface, support remote programming, status monitoring, and fault diagnosis.

IV. Typical Application Scenarios

Multi-generator parallel power station: 2 or more diesel/gasoline generators in parallel, load distribution, stable power supply.

Backup power system: UPS and generator in parallel, seamless switching of primary and backup power sources.

Marine power system: Marine multi-generator grid connection, ensuring safe power supply during navigation.

Island micro-grid: Remote areas, islands with independent power grids, multi-generator coordinated stable operation.

Industrial self-owned power plant: Enterprise self-owned generator sets connected to the city power grid or isolated grid.
