Substation Automation Services

Retrofitting and Upgradation Services

As they say change is only constant thing and your substations are no exception to that. With change in technology or due to end of product life-cycle we need to keep upgrading our assets. We support in doing retrofit of Relays with either one to one replacement or by using advance version relays. Also we do up gradation of your old SCADA with new hardware or software or both.

Our Services Includes:

1. Replacement of old Electromechanical Relays with Numerical Relays

2. Replacement of Outdated Numerical Relays with Latest Models

3. Up gradation of existing SCADA system

4. Integration of additional Devices into existing SCADA

Substation Automation Testing and Commissioning Services

We support in modernizing your substation with our services for Automation and SCADA. We have worked and completed projects on all leading automation systems from reputed manufacturers like SIEMENS, Schneider, GE-Alstom and ABB. We also hold expertise in integrating IED’s of different makes into a SCADA system by using interoperability.

We have worked on below software:

1.     SIEMENS SICAM PAS
2.     SIEMENS WinCC
3.     SIMENS SICAM 230
4.     GE Alstom PaCiS
5.     Schneider ECO SUI

 

In most of the small- and mid-sized industries, processes are automated by means of industrial PLC. However, critical power assets like circuit breakers, relays, transformers, battery banks and other auxiliary switchgears, etc. are often not automated.All these important assets mostly work offline without getting monitored on a continuous basis and thus we fail to collect important data which could be utilised to maintain and operate the assets more efficiently.

Myths behind this scenario

Myth 1: Substation automation solutions are very costly as they do not justify their cost.

This is a most talked about myth in the industry. Initially, as solutions were designed to cater to mainly the utility sector which works on a very large scale, costs were higher. But now you can get a solution customised to meet the requirement of small- and mid-sized industries. All major OEMs now offer such solutions mostly with the help of their authorised partners/system integrators. Such partners or system integrators are equipped with expert level knowledge and also they have reduced overheads for engineering, manufacturing and services, making solution viable both technically and economically. Also, reachability and service availability has become better.

Myth 2: Substation automation is not necessary for our scale of industry as we can manage manually.

Let us accept the fact that while the world is moving, you cannot stay back. Sooner or later you have to catch up with new technology. Technology helps you to navigate in difficult times, e.g., consider the latest situation caused due to COVID-19 wherein industries need to work with reduced manpower. In such a scenario, if one has automation in place, then one can manage the uninterrupted power supply to their plants even with less men at work or you can even control things remotely. As in substation automation, you can monitor and control all your assets at one place.

We at DSG Enterprises, are working extensively to give our customer the flavour of substation automation technology at prices affordable to them without compromising on features.
