What is Trackso’s solar PV DG Controller?

When the grid goes off , a diesel generator (DG) acts as a reference source for an on-grid solar power plant. However, if the solar power plant produces extra power, it can damage the DG by reverse feed.

TrackSo’s Solar DG synchronization continuously monitors the DG power and smartly instructs the inverter to adjust its working efficiency, thus ensuring zero backfeed to the DG.

How does the Solar DG Synchronization Controller work?

Data Collection and Controlling:

TrackSo PV DG Controller/ Device is an advanced device designed to seamlessly integrate PV solar and Diesel Generator systems. The controller collects the data from the DG MFM that is installed on the DG output line and smartly controls the generation of the inverters as per the current load requirements.

The controller ensures that there is no reverse feed to the DG through the inverters and the DG runs at 25-30% efficiency to save fuel consumption.

Data Sending and Storage:

The controller then transmits the data to the TrackSo platform via the Internet, ensuring real-time visibility of your solar plants. Collected data is temporarily/permanently stored locally depending on the data logger model.

Flexibility:

These controllers include Digital Input/Output (DI/DO) ports, which can be used for controlling or monitoring additional devices like relays or alarms.

Frequently Asked Questions

What is DG synchronization in solar?

Smartly Distributes the total demanded load between Solar and DG in such way that the DG runs at the minimum possible load, securing against reversefeedingand protecting the inverters from over-frequency damage, while also increasing fuel efficiency.

What are the requirements for synchronization of DG?

Basically DG Synchronization panels are mainly designed for meeting critical aspects of Power system requirements which primarily includes uninterrupted or flashing restoration of Power supply along with DG and circuitry protection for an infrastructure of social or commercial values and repute.

How to synchronize dg sets?

As you know, synchronization is simply the parallel operation of two or more generators sets sharing the load according to their ratings. Synchronization requires Voltage, Frequency, Phase angle and Phase rotation of all the alternators to be same.

What is the purpose of generator synchronization?

A generator cannot deliver power to an electrical power system unless all the aforementioned parameters exactly match those of the network. The need for synchronization arises when two or more alternators work together to supply the power to the load.

What is the purpose of synchronizing panel?

Synchronization panels are mainly designed and used to meet power system requirements. Synchronizing panel will operate on an automatic mains failure system, so that when the main supply is interrupted on one or all phases (after an adjustable delay period) the generator sets will start-up together.

What is the principle of DG synchronization panel?

Whenever the main grid supply fails, Synchronizing relay comes into action and give control signal to alternate sources. So DG connected to common busbars. After that initial warmup, DG starts and allowed to rotate at full speed.

Can DG synchronization be used for both on-grid and off-grid solar systems?

Yes, DG synchronization can be used in both on-grid and off-grid solar systems, providing uninterrupted power in off-grid systems and efficient energy management in on-grid systems.

What are the key components needed for DG synchronization?

The key components for DG synchronization include a synchronization panel, inverter, DG controller, and communication interfaces between the DG and solar system to manage the power output efficiently.

Does DG synchronization reduce fuel consumption?

Yes, DG synchronization allows the solar system to take priority, reducing the reliance on the diesel generator. This leads to significant fuel savings as the DG only operates when solar power is insufficient.

What happens during a grid outage with DG synchronization in place?

During a grid outage, the synchronized DG will automatically start and provide the required power, ensuring that the solar system continues to operate without interruption.

Is there any maintenance required for the DG synchronization system?

Regular maintenance of the synchronization panel, controllers, and connections is recommended to ensure optimal performance. The diesel generator should also be maintained as per manufacturer guidelines.
