Synchronizing Panel

Synchronizing Panel is an intelligent electrical control system used to parallel multiple power sources typically two or more diesel generators (DG sets) or a generator with the utility grid to operate as a single combined power source.

Core Components

§  Synchronizing Controller: 
The "brain" (e.g., DeepSea, Woodward, or ComAp) that calculates the phase differences and manages the logic.

§  Motorized Breakers: 
High-capacity Air Circuit Breakers (ACBs) that can be closed electronically by the controller at the exact millisecond of synchronization.

§  Synchroscope: 
A visual meter that shows the phase relationship between the sources (mostly used for manual backup).

§  Load Sharing Modules: 
Electronics that communicate between generators to balance the "push" of electricity.  

Primary Functions

§  Auto-Synchronization: 
Automatically adjusts the speed (frequency) and excitation (voltage) of an incoming generator to match the "live" busbar perfectly before closing the circuit breaker.

§  Load Sharing: 
Evenly distributes the total electrical demand (both kW and kVAR) among all running generators so that no single engine is overloaded while others sit idle.

§  Load Management (AMF Integration):
These panels act as smart managers, automatically starting additional generators as demand rises and shutting them down when demand falls to save fuel.

§  Dead Bus Sensing: 
Detects when the busbar has no power and allows the first available generator to close its breaker instantly.

§  Reverse Power Protection: 
Prevents a generator from acting like a motor (drawing power instead of producing it), which could destroy the engine. 

Why Use One? 

§  Redundancy: 
If one generator fails, the others continue to carry the critical load without a total blackout.

§  Fuel Efficiency: 
Instead of running one massive generator at 20% load, you can run one small generator at 80% load. 

§  Flexibility: 
Allows for maintenance on one engine while the building remains powered by the others.
