IPDS for sub transmission & distribution network

by Team Digireach

India is a developing country. Power is the mainstay for any growing country. In order to leapfrog into the future, efficient utilization of power generation is of prime importance.

Electricity is the most important factor in the economic growth of any country. And the most critical segment of Power Sector chain including Generation, Transmission and Distribution, is the Distribution Sector. Efficient management of the distribution of electricity sector is mandatory as it acts as an interface between the utilities and the consumers. The real challenge in the power sector today lies in efficiency. However, the poor financial health of the distribution utilities in the States has resulted in inadequate investment in the distribution network making it difficult to meet the increasing demands of power in urban areas.

The goal of IPDS (Integrated Power Development Scheme)  are as follows:

  1. Strengthening of sub-transmission and distribution network in the urban areas;
    Metering of distribution transformers /feeders / consumers in the urban areas.
    3. IT enablement of distribution sector and strengthening of distribution network

The problems the government tries to address by implementing this scheme are as follows:

AT&C losses [The concept of Aggregate Technical & Commercial losses provides a realistic picture of loss situation in the context it is measured. It is combination of energy loss (Technical loss + Theft + inefficiency in billing) & commercial loss (Default in payment + inefficiency in collection).]

  • Establishment of IT enabled energy accounting / auditing system,
  • Improvement in billed energy based on metered consumption
  • Improvement in collection efficiency.

This is a part of the Indian government scheme of Restructured Accelerated Power Development and completion of the Reforms Programme (RAPDRP). It is a flagship programme of the Ministry of Power.

IPDS is important for a brighter future which will help enhance the economic growth of India. Electricity is vital for the overall development of the nation, and the Union Government by launching this scheme is all set to push India in the right direction of development.

Status as per No. 8/2/201 8-IPDS(Pt.) Government of lndia Ministry of Power

Projects worth Rs.30,005 Crore (Distribution Strenglhening work: Rs 2.7,626 Crore in 546 circles, IT enablement: Rs 985 crore in 1931 towns, ERP Rs 640 crore and Smart Meting: Rs 754 crore) have been sanctioned.

Better electricity leads to a better tomorrow. We, at Digital Reach are equipped with the hardware, software, system integration capabilities and domain knowledge to make this a reality.

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

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.
