A National Workshop on

Real-Time Digital Simulation for Power Engineering Applications

IEEE Student Branch Chapter IIT Mandi in collaboration with IEEE IAS SB Chapter of IIT Mandi organized a

national workshop on “Real-Time Digital Simulation for Power Engineering Applications”, 13-16 June 2019

at IIT Mandi. This workshop was partially sponsored by IEEE IAS and Science and Engineering Research

Board (SERB), India. The workshop’s objective was to enhance the knowledge of the participants in the

area of the “Real-Time Digital Simulation for Power Engineering Applications”. With the theme of “Real-

Time Digital Simulation for Power Engineering Applications,” this event was providing an environment

for research scholars, faculty members and industry personnel to know, grow, develop, experience and

exchange their ideas to fortifying the technological developments. Modern power systems are progressing

towards the cutting-edge technology which demands the whole new ideas in operations, power

management/utilization and this makes the real time simulators inevitable. So flexible, scalable, fast and

practical ground based real time digital system is the key requirement of the present electrical power systems.

Here at IIT Mandi, we usually carry out our complex and critical research works fluently with such state-of-

the-art real time digital simulator system. The drive of this workshop is to provide on acquaintance to the

participants in the direction of real-time digital simulation used for power engineering and industrial

applications. Our motive is to deliver latest and best-in-class procedural training to participants. This

program was including lecture sessions, discussions on research issues by the participants, poster

presentation and most importantly an intensive hands-on training on state-of-the-art digital simulators which

are available in the power engineering laboratory of IIT Mandi.

A unique, national level opportunity which delved into the high-level, strategic issues relating to

applications of the Power System Engineering, Power Electronics, Electrical Machines and Renewable

Energy systems. The workshop provided a platform for an in-depth discussion on the various challenges

and their possible remedies which benefited participants from academic/ R&D institutions and engineers.

The 04 days workshop was included demonstration experiments/ training on Real Time Digital Simulator

(RTDS) and OPAL-RT and research solutions for the Power Engineering applications.

The workshop was attended by the students of IIT Mandi and other institutes. The workshop on real-time

computing is to bring together researchers working on real-time systems (undergraduate and graduate

students and PhD students, faculty members, postdocs, etc.). The workshop provides a relaxed forum to

present and discuss new ideas, to explore new research directions, and to review current trends in the real-

time systems area. It is based on both short presentations and hands on experience session to encourage

stimulating discussions.

The scope of the workshop includes (but is not limited to) the following areas:

Real-time system design and analysis: task and message scheduling, modelling, verification, worst-case

execution time estimation, distributed systems, fault tolerance, quality of service.

Infrastructure and hardware for real-time systems: Advance electrical machine drives, power electronics

converters, power generation, transmission and distribution system.

Software technologies for real-time systems: compilers, programming languages and component-based

technologies.

Real-time applications: Robotics and automation, power generation system, electrical drives and etc.

Speaking about the impact of the workshop, Dr. Bharat S. Rajpurohit, coordinator of the

workshop and Associate Professor, School of Computing and Electrical Engineering, IIT Mandi, said,

that the large number of participant registrations shows the importance and significance of learning RTDS

and Opal RT tool. Since the topic of the workshop was related to the their academic and curriculum growth,

participants from different streams have shown their interest towards the workshop. There were more than

65 candidate registration in total out of which approximately 35 were from other neighboring state institutes.

He also greeted the resource persons from RTDS and Opal RT who took efforts and time confirming their

attendance to the workshop for giving hands on training to the attendees.

Highlighting the unique aspects of this workshop, Prof. S. N. Singh, Fellow, IEEE, Vice chancellor,

MMMUT, Gorakhpur, India, delivered lecture on “Estimation of Grid Harmonics in the Presence of

Renewable Energy Sources”. Prof. Singh briefed major concerns of power system design & operation

like; Quality, Reliability, Security and Economy. He covered major issues and challenges in Power System

Applications. He also discusses on role of Power Electronics Applications in Power Systems and why

Harmonics are matter of concerns. Prof. Singh has covered stat-of-art signal processing and intelligent

techniques for estimation of non-stationary harmonics. He has shared several experimental results to support

the analytical foundations. The participants raised several questions related to current scenario of power

system stability

and issues about harmonics.

Prof. S. N Singh obtained his M. Tech and PhD in Electrical Engineering from Indian Institute of

Technology Kanpur, in 1989 and 1995 respectively. Presently, he is a Vice Chancellor at Madan Mohan

Malviya University of Technology, Gorakhpur and leave from Professor (HAG), Department of Electrical

Engineering, Indian Institute of Technology Kanpur, India. Before joining IIT Kanpur as an Associate

Professor, Dr. Singh worked with UP State Electricity Board as an Assistant Engineer from 1988 to 1996,

with Roorkee University (now IIT Roorkee) as Assistant Professor from 1996 to 2000 and with Asian

Institute of Technology, Bangkok, Thailand as Assistant Professor from 2001 to 2002.

The chief guest of workshop was Prof. Ramesh Oruganti. He is an Adjunct professor at Indian

Institute of Technology Mandi. Prof. Ramesh obtained his M. Tech from IIT Madras in 1972 and Ph.D.

from Virginia Tech. University in 1987. His research interest on an efficient and high-performance DC-DC

power conversion, AC-AC power converters for improved power quality and high-performance stand alone

and grid connected inverters for renewable energy and other applications. Prof. Oruganti introduced about

how Real -Time Digital Simulation useful for Power Electronics applications. He also highlighted on the

significance of these tool in industries.

Dr. Prem Felix, Associate professor, IIT Mandi, said, that the workshop on Real Time Digital

Simulation for Power Engineering Applications is very useful in academic as well as industry research

department. Also, he introduced about different school of IIT Mandi and why IIT Mandi has no department

like private institute. He said, when we are classified department according to Engineering field then our

knowledge is bounded to only that department but in IIT Mandi has four schools instead of department. So,

research scholars and faculties are involved in various field and do effectively research.
