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

IPDS (Integrated Power Development Scheme)

by Team Digireach

We are moving to an energy intensive world. Among the different stages of electricity generation and consumption, distribution is a primary area where we can make necessary adjustments in the power sector value chain to increase efficiency drastically.

One of the features of the Indian power sector reforms is the increased attention to the distribution sector. Systems and procedures for monitoring Quality of Service (QoS) of distribution utilities have been finalized by State Electricity Regulatory Commissions, especially subsequent to the Electricity Act 2003.

Distribution is the most important link in the entire power sector value chain.  As the only interface between utilities and consumers, it is the cash register for the entire sector. Under the Indian Constitution, power is a Concurrent subject and the responsibility for distribution and supply of power to rural and urban consumers rests with the states.

Systems to improve consumer interface, quantify performance and to monitor progress in a transparent manner are necessary and welcome steps. QoS process meets one of the many long felt needs to improve distribution sector. At this initial stage, it is crucial that the distribution utilities and regulatory commissions show serious end to end commitment in the QoS process. This includes the steps of formulating the system, reporting performance, monitoring progress and taking corrective measures. It is also important to proactively work for the active participation of consumers at all stages of the process. With such an approach, over the years, QoS process can evolve to be the necessary and sufficient condition for continuous improvement of the distribution sector.

Government of India provides assistance to states through various Central Sector / centrally sponsored schemes for improving the distribution sector. Integrated Power Development Scheme (IPDS) approved on 20.11.2014 with a total outlay of Rs 32,612 crore which includes a budgetary support of Rs 25,354 crore from Govt. of India. The objectives of scheme are:

  • Strengthening of sub-transmission and distribution networks in the urban areas
  • Metering of distribution transformers / feeders / consumers in the urban area.
  • IT enablement of distribution sector and strengthening of distribution network
