Distribution System Capacitor Banks And their Impact On Power Quality
The most common solution to harmonic problems involves the application of harmonic filters. Capacitors and the system short-circuit impedance combine to create resonances that can magnify harmonic levels to well above accepted limits. What is the solution? - Dr L Ashok Kumar
Qualitative Testing of DLMS/COSEM ICS compliant Energy Meters
The Device Language Message Specification (DLMS) and Companion Specification for Energy Metering (COSEM) form together the DLMS/COSEM application layer communication protocol and an interface model for metering applications. The requirement of an Open Protocol for energy metering was necessary for bringing in homogeneity among various makes of meters. - V Suresh and V Arunachalam
Electric Vehicles Charging up for a Better Future
As vehicle use continues to increase, many countries around the world are focusing on ways to decrease pollution, greenhouse gas emissions and dependence on oil. Promoting less polluting non-oil based propulsion systems is an effective way to address these issues. Of all emerging the road transportation technologies that use fuels other than carbon based fuels, Plugin Electric Vehicles (PEV) are the ones closest to mainstream. India, with its high dependence on oil imports and having cities with some of the highest air pollution levels in the world, can benefit with large scale adoption of PEVs on this roads as the technology matures. - Girish Shirodkar and Shantanu Gautam
Minimization of Power Loss & Improvement in Voltage Profile of 11kV Feeder by Different...
One of the greatest and the most obvious problem that India & the other developing countries are facing today is the increasing demand of electricity and its poor supply. The rising gap between demand and supply of electricity is the major factor of concern to developing countries like India. The power generation cannot be increased over night, and involves lot of investments. However, the present day scenario can be improved if we apply some more scientific techniques and methods to reduce power loss in distribution system. - Rahul Sharma
Enabling Smarter Grid Automation through Standardization
Power grid is a combination of various network elements and electrical components used to generate, transmit, distribute and supply power to end users of electricity. Complexity of power system has been growing tremendously over the last few decades, facing new challenges and targets during its operation. In order to overcome some of these major challenges, there is a definite need of automation which helps in automatically operating & controlling the power system under various situations of operating grid in day-day scenarios. The new era of smart grid in the 21st century has made automation and standardization really a need to operate grid under the dynamics of rapid load changes, making the system more time sensitive towards faults and failure modes. This research article presents analysis & overview on emerging technology and standards over past few years for smart grid automation, from generation to utilization making Indian power grids to operate in efficient manner and resilient to failure modes. - Balakrishna P &

Optimal Placement Techniques for Distributed Generation
Electrical power is transmitted through the transmission systems from the central generating stations to the end users using a series of distribution transformers and lines. From around 1990, there has been a growing interest in connecting generations directly to the distribution system, known as Distributed Generation (DG) or Distributed Energy Resources (DER). In some countries, a strict definition of distributed generation is made, based either on the rating of the plant or on the voltage level to which it is connected to the grid. However, these definitions usually follow technical documents. - P Pavani and Dr S N Singh
Contact Solutions for High and Medium Voltage Systems in PTD
Even today, electric contacts in power transmission and distribution systems are still made using screw or nut-bolt. Most of the time, however, there is...
Preventing Electrical Fires
Shockingly, almost 90 percent of all fire accidents originate from “electrical” causes, and behind a vast majority of these fires are low-quality wires and cables, that is, either low-quality insulation or inferior conductor or both. The article provides a snapshot of how consumers, consultants, specifiers and decision-makers can avoid dreadful consequences by choosing the right kind of wires and cables. - Pratap M Anam
Towards Zero Emission of Greenhouse Gases
For decades climate scientists have warned to limit the human influence on ecosystem and climate that led to global warming and climate change. Now they say we have very little time to act. The Intergovernmental Panel for Climate Change (IPCC), a global institution that studies climate change, has recently released another alarming report that bespeaks the increasing harm we humans are doing to the environment in the form of greenhouse gases emissions. This disrupts the climate more and raises global warming. There should be zero emission of greenhouse gases by 2100, the report suggests, if there has to be no further rise in the temperature. That means, all nations have to phase out the usage of fossil fuel by end of this century. - J Devaprakash
Inverter Heart of solar system
India is one of the fastest growing economies in the world like China, South Africa, Russia and Brazil. It is the second largest country in the world as far as population is concerned and fifth largest country in the world after USA, China, Russia and Japan as far as electricity generation is concerned, in spite of that its per capita power consumption is merely 920 units. There is a huge gap in power generation and peak power demand. Renewable energy is one of the most viable solutions as we are facing serious consequences of global warming all around the globe. - Aqeel Ahmad
Standby Diesel Generator Sets Issues related to Selection/ Sizing, Installation, Operation & Maintenance
India is world’s fourth largest growing economy. Our currently available power capacity is approximately 40% short of total demand. As a result the State Electricity Boards have to control the power distribution by imposing 'Load Shedding' to Industrial, Commercial and Residual consumers in a phased manner. For sustainable development, the growth in power demand will be never ending. - S N Chavan
Smart Grid Technology Particular Reference to Indian Power System
Smart Grid is adding necessary measuring, monitoring, communication, analysis and control capabilities to bring efficiency and optimization in electricity sector by integrating IT Technology onto the power network. - Robbin Pramanick
Cost Effective approaches for SPV Projects & Energy Efficient Equipment
Today’s power scenario in the world and in India in particular has changed from that of 'Generation, Transmission,Distribution' to 'Generation, Storage, Distribution & Effective usage'. Solar power generation especially at the last milestone has been recognised as the need of the hour and though, India has not woken up to the effective storage and efficient use of power, the world at large is seriously looking at these dimensions. - S V Rao
Distribution Companies Financials Living on the edge
The article takes a peep into the some of the problems faced by distribution companies and attempts to analyze the major reasons for the current financial state of the DISCOMs in India. He establishes the need for a wholesome and holistic approach to stem the rot rather than piece-meal efforts. “Inadequate or piece-meal response to danger signals can only have catastrophic consequences. After all if you try to plug a leaking dam with your fingers, you will soon run out of fingers". - Shahji Jacob
