Message from our Chancellor

Excerpt selected from the address of Sri Mata Amritanandamayi Devi upon receiving the

Doctorate of Humane letters from State University of New York 25 May 2010.

“Knowledge is like a river. Its nature is to constantly flow. Wherever it can flow, it does so,

nourishing culture. On the other hand, the same knowledge, if devoid of values becomes a source of

destruction for the world. When values and knowledge become one, there can be no more powerful

instrument for the welfare of humankind. Today, physicists have even begun investigating the

possibility that the essential substratum of the manifest universe and the individual are one and the

same.

We are standing on the threshold of a new era wherein material science and spirituality will

move forward hand in hand. It is Amma’s prayer that we develop the expansive-mindedness to

embrace both scientific knowledge and spiritual wisdom. We can no longer afford to see these two

streams of knowledge as flowing in opposite directions. In truth, they complement one another. If

we merge these streams, we will find that we are able to create a mighty river—a river whose

waters can remove suffering and spread life to all of humanity .”

- Amma

Preface

Dr. P.S. Chandramohan Conference Chair Professor & Chairman Dept. of Electrical and Electronics Engineering

Energy is an essential input for modern living. The development of human civilization is

directly linked to tapping and utilisation of natural energy resources. Today the availability and

utilisation pattern of energy are important parameters influencing the economy of any country. The

heavy dependence on fossil fuels clubbed with the habit of unscrupulous usage of energy and its

wastage have led our mother earth to environmental degradation, climatic changes and the

detrimental global warming. Unless efficient energy management is done by increasing energy

efficiency in all walks of life, avoiding/ reducing energy wastage and utilising the available

renewable energy sources to the extent possible, the catastrophic end of human race cannot be

avoided.

Technological developments continue to march forward. From the level of moving heavy

stones to distant sites using wooden logs, we are now fine tuning our technology to take up

interplanetary travels. The pre-historic people were satisfied with mere food and shelter; whereas,

the modern men live amidst countless luxuries and comforts. Energy is a truly interdisciplinary

area where blends of technological developments find their immediate applications. Not only the

scientific and technological developments but also the roles of social scientists, policy makers and

bureaucrats are indispensible in an energy management scenario.

Energy does not mean electricity alone. However today, the most convenient and most

widely used form of energy is electrical energy. It is not a primary source of energy, but a

converted, secondary form of energy derived from some primary source of energy. These primary

sources are so varied in nature and thus the conversion to electrical energy also adapts various

routes or methodologies.

vi

The generation, transmission and utilisation of electrical energy face many challenges

today. The history of electrical industry started with tiny dc generators supplying power to a local

surrounding area at the generated voltage itself. The invention of transformers made different

voltage levels possible for the generation, transmission and distribution. At the same time, dc was

not wiped off from the scene. In fact it strengthened the grid with HVDC transmission systems. The

power converter technology only made the integration of HVDC into the electricity grid possible.

Over the past century, the power systems grew from the single generator systems to

interconnected systems. The power systems are interconnected to achieve improved reliability,

stability and economic operation. The interconnection started by paralleling of generators and then

moved on to interconnecting generating stations of different kind. It expanded further by formation

of a larger grid at state level, regional level and national level. Today, international tie-lines have

been established that make power sharing between countries possible. Power engineers are

recently thinking of establishing interconnection between continental networks to facilitate power

transmission making use of the day-night variations, and accordingly the time-shift in their peak

loads, so that load sharing and utilisation of resources could be done on a larger scale.

It is true that the integrated operation of power systems provided many advantages. At the

same time it brought in many challenges before the power system operating engineers. It is to be

noted that power system is such an exciting and thrilling area where we need application of almost

all fields of engineering, especially electrical engineering. Specialists in power systems, electrical

machines, control systems, high voltage engineering, computer science and technology, electronics

and communication, power electronics, material sciences etc. find their comfortable carrier in

power and energy field.

The widespread increasing utilization of decentralized renewable energy sources most

often demand existence of islanded systems and operation of DC systems. Regarding the

distribution side is concerned; it is soon going to be a co-existing scenario of both ac and dc

systems. It appears that most of the electrical appliances, especially the domestic gadgets are likely

to adapt to dc distribution and the power loads may be supplied with 3-phase ac.

As the globally accepted electricity distribution system so far had been ac and most of the

devices and appliances of today work with converted dc from ac, it resulted in harmonic pollution

in power systems and the increased energy losses due to harmonics. For the past two decades

harmonics management had been a hot area for power system research. It brought in many

techniques like passive, active and hybrid filters. So many techniques and algorithms were

vii

developed for its identification and control. Several new techniques and devices introduced for

enhancement of energy efficiency also added harmonics into the power system.

Making the power supply available to the end users by looking after its security, stability,

safety and reliability throw many challenges before the power and energy engineers. As

innovations and new developments taking place in laboratories are moved into the field, it may

create more opportunities or revolutionise the operations in the field or sometimes may even wipe

off the existing practices and devices. The relaying and protection can be cited as a very good

example for this. When the static relays and digital relays were introduced, their electromechanical

counterparts had already become very reliable and time tested so that there was resistance to

change. And now it is the comprehensive computer protection schemes found comfortable with

many operations and applications. The electromechanical relays and many of its static versions

have moved into darkness.

The industry-academia interface has to be very vital so that challenges in the field are

brought to the attention of researchers who are comfortable with chasing such problems. One way

to vitalise such a creative interaction can be through conferences that provide a conducive forum

for many discussions, debates and deliberations. Generation of thoughts to sharpen technologies to

face new challenges can be realised more through such interactions.

Here, a maiden attempt is made by the Dept. of EEE, the youngest department in the

Amritapuri campus to have a regular annual conference on Technological Applications in Power

and Energy (TAP Energy). We hope it will materialise the above said goals as well as it will provide

a venue for the power and energy fraternity to establish long lasting friendship/ partnership and

share their wonderful thoughts for strengthening research in this most essential area for humanity,

the Power and Energy engineering. I congratulate and thank my sincere young enthusiastic

colleagues to take up this huge task of organising the TAP Energy Conference.

With the blessings of our beloved Amma, Satguru Sri. Mata Amritanandamayi Devi, the great

humanitarian leader and Chancellor of this Amrita University, I sincerely hope this recurring annual

conference will contribute quite a lot in the coming days.
