Product brief description
HAS-111 DG is an intelligent parallel relay specially designed by DEIF for power systems.The core features include:
Synchronous condition detection:voltage difference,frequency difference,phase angle difference triple criterion
Analog output:Support frequency and voltage signal outgoing adjustment
Compact installation:35mm DIN rails or bases flexible deployment
Product details
1.Functional architecture and synchronization logic
Core detection mechanism
Three-parameter synchronization criteria:
At the same time,the voltage difference between the busbar and the generator(±2%~±12%adjustable),frequency difference(-1Hz~+1Hz adjustable),and phase angle difference are monitored,and the synchronization pulse is triggered when all conditions are met.
Dynamic threshold settings:
Localized parameter adjustment through panel potentiometer
Signal interaction design
Analog output:
Provides independent output of frequency(4~20mA)and voltage(0~10V),compatible with DEIF LSU series load distribution unit
Status indicator:
Dual LEDs display synchronous progress and system status in real time(ready/delay/failure)
2.System integration and extension
Linkage control
Island synchronization support:
Automatic synchronization of generator and another device(such as shaft-with generator)can be achieved
Factory level synchronization:
Multiple HAS-111 DG coordinated control to realize grid connection of the entire field generator
Environmental adaptability
Anti-interference design:
Isolated input circuit suppresses grid harmonic interference
Installation Compatibility:
Standard DIN rails are suitable for mainstream distribution cabinet layout
Product Overview:HAS-111 DG
HAS-111 DG is a high-reliability synchronization relay developed by DEIF for parallel generator set scenarios.It is linked with analog output through precise parameter threshold control to ensure safe grid connection in scenarios such as ships and distributed power stations,and supports multi-mode synchronization operations from manual to semi-automatic.
