DA (Distribution Automation) 

 

Traditionally, utilities substation has focused on automation functions such as monitoring, controlling, and collecting data inside the substation.  This traditional scope allows for effective control of automatic devices located within the substation fence, but it does not fully take advantage of automated feeder devices.  

The arrival of the Smart Grid comes a new level of possibilities with increased control of relays, capacitor banks, and voltage regulators along the feeders.  It also brings a new level of possibilities with the increased control and interaction of distributed energy resources, AMI and DR functions. 

The fast smart grid technologies development has created the urgent need for a new generation of Smart Grid Distribution Automation (DA) Solution for the utilities companies.

What is Smart Grid DA Solution? 

 

Smart Grid Distribution Automation (DA) solution is a new generation of automation solution allowing the utilities substations to play a highly expanded and important role in the "smartness" of the grid than in the past.  

It allows a substation to act as a decentralized nerve center, to enable the network to be more efficient and more reliable locally, while it is still connected to a higher level of intelligent with a wider perspective, e.g. SCADA / EMS / DMS systems.

Smart Grid DA Solution focuses on integration using global standards (IEEE and IEC) of three main groups of components :

1) Smart IEDs (Intelligent Electronic Devices) for sensing, measuring, and control of network parameters and equipment;

2) Interoperable communications networks to tie the different pieces together;

3) Software application at various levels of the network including the substation system that can manage the other pieces of the automation system.

 

 

Benefits of Smart Grid DA Solution 

 

Smart Grid Distribution Automation (DA) Solution has the following benefits:

- Interoperability, distributed intelligence,  integrated communications and systems for greater efficiency and reliability of the equipment, network, and energy supply.

- Significant financial gain from reduced transmitted energy losses.  Utilizing the networks more efficiently allow a longer life of equipment and an increased throughput of energy.  Using the intelligence in the network applications and automation, substation peak loads can be manipulated and reduced.

- Reduction of green house gas emissions and improved customer satisfaction through higher reliability and reduced outages.
