What is DG Synchronization?
DG synchronization refers to the act of synchronizing voltage, frequency, and phase angle of a generator with another generator or grid prior to connection. This is done to allow for a smooth power transfer and avoid electrical disturbance or system damage.
The DEIF HAS-111 is instrumental in automatic synchronization through:
- Synchronizing generator voltage and frequency with the grid
- Phase alignment prior to circuit breaker closing
- Prevention of reverse power flow and electrical instability
Understanding Circuit Breaker Closing in Synchronization
A circuit breaker makes or breaks electrical circuits to safeguard equipment against faults. In synchronization, a circuit breaker should close only when voltage, frequency, and phase are synchronized. The DEIF HAS-111 automates this process to ensure:
- Safe & accurate closing of the breaker
- Prevention of transient currents or electrical surges
- Smooth load transfer without power disruption
Features of DEIF HAS-111 for DG Synchronization
1. Automatic Synchronization
The DEIF HAS-111 constantly checks generator parameters and synchronizes exactly with the grid or other generators.
2. Adaptive Load Sharing Control
Adjusts automatically to load sharing to optimize power distribution across multiple DGs.
3. High-Speed Circuit Breaker Closing
Facilitates rapid and reliable breaker closing to reduce downtime and power instability.
4. Enhanced Protection Mechanisms
Guards generators and electrical systems against faults such as:
- Overvoltage & undervoltage
- Overfrequency & underfrequency
- Reverse power flow
5. User-Friendly Interface & Configuration
It is simple to configure synchronization settings through the easy-to-use interface, with real-time monitoring and control.
