Some top things to know about DG Synchronization

by Tricolite02 Duct system suppliers dg synchronization panel

Quite interestingly, synchronization of the DG sets has always been a hot topic for electrical engineers out there. To be precise, DG synchronization comes with a lot of complicated logic and circuitry, which has made the system tough for engineers to comprehend the subject fully.

Note that synchronization is the procedure of operating two or more DG sets in parallel connection. This operation is accomplished by minimizing the difference of phase-angle and difference in frequency and matching phase sequence.

With huge advancements in technology platforms, the synchronization process is made simpler now. Nowadays, manual intervention is hardly required as DG syncing controllers can control the process easily.

The DG synchronization panel boasts of an easy-to-use interface, which makes the sync process simpler.  

Line Voltage Monitor

Also abbreviated as LVM, Line Voltage Monitor is a type of monitoring relay used for the identification of the availability of supply in the bus. There are other types of LVM which come with added features like reverse phase sequence checking, over-voltage settings, etc. It is imperative to note that LVM provides feedback through the NO and NC contacts.

DG Sync Controller

One of the most important components of the DG Sync process is the controller. To be precise, it is a multi-functional and programmable controller used to control and sync DGs. It also comes equipped with various other functionalities like a protection mechanism for the engine and the alternator. The controller also has analog output ports voltage signals. Here are some of the applications of DG sync panels that you should be aware of.

✔ Engineering Units

✔ Hotels

✔ Processing Plants

✔ Telecom Sector

Advantages of DG Syncing in Parallel Operations

Here is the list of benefits of deploying DG Sync Panels in parallel operations.

✔ One can get the continuous backup of power supply with DG syncing in parallel operations

✔ Saves a great deal of fuel

✔ On the basis of the load condition, the requisite number of DG panels can be operated

✔ When one panel fails, power can be drawn from the other sets without any issues whatsoever

Importance of Speed Bias

Note that the speed bias signal is the voltage signal provided to the engine speed governor to control the engine’s speed. This is usually done to match with the frequency emitted by the DG sync panels.

The DG synchronizing panel suppliers nowadays equip the panels with CAN communication channels with the help of which the DG panel can communicate with the engine. Furthermore, electrically operated ACBs are also a popular option for the incomer and utility feeders.

It is worth noting here that for automatic syncing, pre-programmed microprocessor-based relays are widely used. What’s more, the whole process is executed stepwise without any human intervention.

Always opt for those suppliers who provide built-in alternate protections and load management systems. Also, check the condition of the auxiliary control during delivery to avoid future issues. Let’s hope the things discussed above would now help you comprehend the core issues of DG sync panels.
