- Main Features
- Precise Load Distribution: It adopts an advanced proportional-integral-derivative (PID) control algorithm to achieve precise power distribution among multiple generators. It also supports independent adjustment of active and reactive power to meet the needs of different load types.
- Intelligent Parallel Control: Through CAN bus communication, it realizes the synchronous operation of multiple generator sets. The automatic synchronization function ensures that the units are connected to the grid when the voltage, frequency, and phase are consistent, and the inrush current is less than 5% of the rated value. It also supports droop control for parallel operation without interconnection lines.
- Complete Protection Function: It has protection functions such as over-frequency, under-frequency, over-voltage, under-voltage, and reverse power. The fault recording function records the electrical parameters during abnormal conditions, which is convenient for fault analysis. In addition, its hot standby function ensures that the system continues to operate when the main controller fails.
- Application Field
- It is mainly used in power generation systems, such as data center backup power systems and island microgrid projects. For example, in a data center backup power system, it can manage the parallel operation of 4 2000kW diesel generators, complete the start-up, synchronization, and load distribution of the units within 10 seconds when the commercial power fails, and ensure the uninterrupted power supply of servers.
