RT DAS and AT&C Losses

by Team Digireach

RT DAS consists of two distinct important terms.

Data acquisition system is the accumulation of data. Real-time means its is based on the time at which it is performed. The delay of data collection is insignificant hence it is real-time. The time delay of transfer of audio signals when we are in a telephonic conversation is called real-time. The person receiving the audio signals is able to initiate conversation based on the audio input he gets from the speaker in real-time. The response is immediate. Having a delay in the data capturing technology will lead to a system failure in certain circumstances.

 

The other part is acquisition and storage. Collection of important parameters leads to study of the functioning of the system. The operator or administrator can plan accordingly and take preventive action which can increase the efficiency of the system. The purpose of any data acquisition system is to gather useful measurement data for monitoring and control.

Major areas of concern in the power distribution sector are high AT&C loss and poor power distribution reliability.  Hence, RT DAS comes into the picture. To address these problems, accurate measurement, diagnosis and remedial action is essential. Some of the parameters based on which the reliability of power is measured in the terms of SAIFI and SAIDI which requires solution based on real time.

To accurately measure reliability of power distribution network and facilitate utility to take suitable administrative action for enhancement of power reliability. The measurement of reliability shall be ensured by a real time data acquisition system (RTDAS) using RTU at substation.

AT & C LOSS(Aggregate Technical and Commercial Loss)

In absence of feeder metering in the past, there was huge losses in terms of T&D and theft of electricity in agricultural consumption. Agriculture consumption is around 25%, utilities were showing I as 40% and correspondingly T&D losses shown as 25%. There was obviously a large amount of theft. T&D loss figures did not capture the major gap between the billing and the collection. AT&C was introduced to get over this particular problem.

What is AT&C loss?

  • It is the difference between units input into the system and the units for which the payment is collected.
  • It is the clearest measure of overall efficiency of the distribution business.
  • AT&C measure both the technical and commercial losses.AT&C Loss(%) = (Energy Input – Energy Realised) X 100

Deployment of IoT

by Team Digireach

The Internet of Things (IoT), also sometimes referred to as the Internet of Everything (IoE), consists of all the web-enabled devices that collect, send and act on data they acquire from their surrounding environments using embedded sensors, processors and communication hardware. These devices, often called “connected” or “smart” devices, can sometimes talk to other related devices, a process called machine-to-machine (M2M) communication. This technology allows for a level of real-time information that we’ve never had before. We can monitor our homes and offices remotely to keep them safe and efficient. Businesses can improve processes to increase productivity and reduce material waste and unforeseen downtime. Sensors in city infrastructure can help reduce road congestion and warn us when infrastructure is in danger of crumbling.

However while this may sound simple enough, its proper deployment is anything but that. An IoT deployment is a process. Unless a business undertakes and completes each part of the process, the deployment will be rich with problems as well as data. Around the world, businesses of many sizes are hitting roadblocks because their IoT deployment is delayed, stalled, refused to work as designed, failed to pass regulatory requirements or didn’t deliver the expected results–sometimes all the above.

  1. Planning- The first step to a good IoT deployment is its planning. This is more about the vision that the management team has in mind about the project than the actual technological aspect of IoT. The management team needs to have a clear grasp of what they and the project have to deliver or the project will be doomed to a premature and unfinished end.
  2. Designing- After setting business goals, designing a compliant network that will deliver them is the second stage. A thorough network design and specification needs to cover the schematic of the network, the choice of components, their locations and identify any issues that might crop up at any point.
  3. Certification- Cellular based IoT deployments also require certain certifications and clearances for the network as well as the devices on it.  Ensuring devices are approved is vital to get the regulatory and carrier sign-offs that mean your deployment can go live.
  4. Testing- No deployment can go live without a thorough period of testing. Testing should not just be about the technology. It is important also to check against the original business goals.

When this process is complete you get to the fifth and final stage where an IoT deployment begins a digital transformation, improves operational efficiency, cuts costs, drives revenues and unlocks profitability.

RT DAS (Real-time Data Acquisition System)

by Team Digireach

In today’s world, data is generated at a brisk pace in all domains. Data is the new oil. We help you capture the data and gain insights from them.

We install sensors and other electrical devices like CTs, PTs, circuit breakers, switches and circuit breakers to collect and register data points.

Real site photos of our successful implementation of RT DAS:

RT-DAS system for SAIFI/ SAIDI measurement: GOI is extending financial assistance through various programmes to establish Feeder Remote Terminal Unit (FRTU). FRTU is an intelligent electronic device designed for use in feeder automation.

FRTU based SAIFI/ SAIDI measurement system in Non SCADA towns to accurately measure reliability of power distribution network and facilitate utility to take suitable administrative action for enhancement of power reliability. The same can be ensured by real time data acquisition system (RT-DAS) using FRTU at substation. It shall also facilitate utility to take appropriate measures for improvement of SAIDI/ SAIFI by knowing the reason of poor values of indices

IPDS (Integrated Power Development Scheme) was approved by the government to strengthen sub-transmission and distribution network inlcuding metering at all levels in urban areas.

Earlier scheme of Restructured Accelerated Power Development and Reforms Programme (R-APDRP) is subsumed in the new scheme of IPDS.

Major components of the scheme are:

  • Strengthening of sub-transmission and distribution network
  • Metering
  • IP application – ERP and cuustomer care service
  • Provisioning of solar panels
  • Ongoing works of R-APDRP to be completed

Advantages of implementing RT DAS:

  • Reports (SAIFI/ SAIDI reports for regulators and as per IEEE norms etc.)
  • Operation monitor to operative cycles of switching devices to have preventive maintenance
  • Data in the form of analytics
  • Historical data and MIS (Management Information System)
  • Future compatibility for controllability and technologies such as SCADA/ AMI etc with addons.

We have project (field/ office) installations of the following devices:

ConnectedSCADA makes RT DAS a possibility for you. Step into the future of electricity with us.

Electric reliability indices like SAIFI, SAIDI, SAIFI, CAIDI, MAIFI can be gathered from these data collected at your centers.
