TWO WEEK ISTE STTP ON ELECTRIC POWER SYSTEM
10th - 15th July 2017
IIT Kharagpur conducted two week ISTE (Indian Society for Technical Education) STTP workshop on "ELECTRIC POWER SYSTEM" under National Mission on Education through ICT (MHRD) organized at Dronacharya College of Engineering, Gurgaon (Remote Centre ID - 1299) from 10th - 15th July 2017.
The experts delivered the lectures during the FDP were: Prof. N.K Kishore (Course Coordinator, Department of Electrical Engineering, IIT Kharagpur), Prof. Shreevardhan. A.Soman (Department of Electrical Engineering, IIT Bombay), Prof. Gautam. Bandyopadyay (Department of Electrical Engineering, IIEST Kolkata), Prof. Kannan M. Moudgalaya (Professor, IIT Bombay) and Mr. Naryana (TCS) .
Day 1 : 10th July, 2017:
The workshop was inaugurated and it was followed by introduction session with the enlightening and motivational words of Prof. N K Kishore, Prof. Shreevardhan A Soman and Prof. Gautam Bandyopadhyay. In the session the participants were briefed with a short overview of topics covered during the 6 days workshop. The first session of the day was on topic Components of Power Systems which was delivered by Prof. S. A. Soman. In the session, various components of Power systems along with Power Flow Analysis and Power Transfer Capability were discussed with the help of different case studies and numerical problems.
The afternoon session started with a presentation on Power System Steady State Operation delivered by Prof. G. Bandyopadhyay. Various important topics of steady state operation such as Types of Load Forecasting, Power Quality and Distortions in Current Signal were discussed.Â Last session of the day was on Symmetrical Faults which was delivered by Prof. G. Bandyopadhyay. He explained various types of faults that may occur during operation of any device and how each type is different from the other. He touched even small details of the topic and explained how we can calculate the value of fault current using methods like Superposition, Z-Bus etc.
Day 2 : 11th July, 2017:
The first session of the day was on "Symmetrical Components" delivered by Prof. G. Bandyopadhyay (Indian Institute of Engineering Science & Technology, Shibpur). In the session, he discussed the Symmetrical Components of Power systems along with the numerical problems on the same. He also discussed the Unsymetrical Fault, Phase Shift of Symmetrical Components in Y-Transformer and effect of unbalanced Loading on Alternators.
The next session by Prof. S.A Soman on Power System Stability covered the details of Star Delta transformers and the Transmission line performance. He also discussed several examples on thesis. The next sessions on "Unsymmetrical Fault Sequence Networks of Unloaded Generators" and "Economic Operation of Power System" were delivered by Prof. G. Bandyopadhyay. He explained the several aspects of unsymmetrical fault with faults on unloaded generator, line to line fault between phases, double line to ground fault, zero sequence equivalent circuit of 3-Ph network along with numerical problems. In the Economic Operation session, he discussed the distribution of plant load among the units, effect of transmission loss in distributing the load among the plants, general loss expression, and optimalload flow, economic dispatch vs. unit commitment and electricity market and economic issues in modern day power systems.
The lectures were followed by question & answer session which was helpful in better understanding of the topics.
Day 3:12th July, 2017
The first session was taken up by Prof. S A Soman on topic Power System Stability. Variations in different parameters within permissible limits were explained, keeping in view the sustainability of the overall system. Different faults and disturbances which deviate the stability were also explained.
The session continued with stability of the system. Different components such as generator, transformer, and transmission lines need to be synchronized to achieve optimum level of stability. In fact, transient, steady state and dynamic stabilities were highlighted in detail.
The next session was regarding power system protection, conducted by Prof. G Bandyopadhayay. Evidently, protection of costly and sensitive electrical appliances is crucial. Switchgear which is a combination of switches, fuses or circuit breakers to control, protect and isolate electrical equipment was explained in detail. The final session continued with power system protection techniques. Major reason for the protection is the different types of faults and sensitivity of electrical equipment. Discussion was mainly regarding protective relays, automatic operation and monitoring equipment's. Last session was reserved for topic related queries.
Day 4 : 13th July, 2017
The first session was taken up by Prof. N K Kishore with an overview of the power system simulation software. Teaching Assistant Mr. Teja gave detailed demonstration of the software. One practical example was solved to make the understanding better.
In the next session major features of simulation software were highlighted by Mr. Teja. Question answer session, in concern with the software was conducted by Prof. N K Kishore. Queries about use of software were answered in the last.
Â Day 5 : 14th July, 2017
On day 5, a quiz was organized which covered the major aspects of all the topics covered during the first 4 days of the workshop. Next session was a discussion of stability of Power System and hands on training on the software PSCAD to find the stability by the eminent Prof. N.K. Kishore. Later session continued on discussion of economics of asset management in electricity utility. The session ended with the discussion on faults on the transmission lines.
Day 6 : 15th July, 2017
Mr. Naryana (TCS) took the first session of the day; he discussed Smart Grid and also introduced the concept of Virtual Power Plants and concluded the session with the discussion of processed tools for smartening the grid. In the next session, participants were introduced to SciLab, which is simulation alternative to MATLAB software. The expert discussed the applications of power systems using SciLab.
The evening session was valedictory ceremony where the efforts being put in by IIT Bombay and IIT Kharagpur to make the NMEICT project a success were highlighted. The ceremony also included a feedback session where the remote centers discussed their views on the FDP. Certificates were awarded to all the workshop participants.
