e-Newsletter - February 2022

From HoD’s Desk

Greetings!

After having semester I of the academic year 2021-22 in the online mode the start of semester II in the offline mode in February 2022 gave immense energy and enthusiasm to all the students and faculty members. Second-year classes are about to face their in-semester examination and third and final-year students are having their fresh start for Semester II. Third-year students spent one month (January 2022) on the internship and final-year students spent it on the project prototyping. The project reviews are completed by mid-Feb.

The offline teaching is going to provide an opportunity for learning through the laboratory sessions, which were missed during the COVID-19 period. While teaching in the class, we observed the differences in the learning levels of students. Because students have spent almost one and half years in the online mode. Bringing all the students back to the earlier environment of teaching-learning is going to be a challenge. Department is also set for the academic audit of Semester I with all files and records. A couple of reviews are also taken for ensuring the compliance of the national board of accreditation committee comments. As per the institute-level expert, some more revisions are required. All are committed to doing that.

GAS-INSULATED SUBSTATIONS (GIS) AND VERY FAST TRANSIENT OVERVOLTAGE (VFTO)

Anuj Paul, BE (Electrical) Div. A

(anujpaul00@rediffmail.com)

Gas Insulated Substation (GIS) is a compact assembly of multiple high-voltage components like buses, circuit-breakers, disconnectors, and related switchgear which are enclosed in a grounded metal housing, insulated by SF6 gas under pressure. Gas Insulated Substations have gained popularity due to their many advantages over Air Insulated Substations like they require very less space only 10-20% as compared to Air Insulated Substations, which makes them easier to install in densely populated areas. They are safer and more reliable, CIGRE reports on reliability and failure statistics have proven that no major aging effects can be seen on GIS, the lifetime of GIS can be up to 60 years. GIS replacement is usually due to the increased need for power supply along with high voltage ratings and current ratings. They have better performance in harsh environmental conditions. The aggressive environment can harm the high voltage components of the substation as well as all the structures and steelworks to fix and hold the high voltage equipment. Because of its gas tightness, no aggressive can enter the high voltage components to cause damage. GIS also requires minimum maintenance once the gas compartment is sealed clean and dry gas conditions exist inside the GIS, the required cleaning processes of insulators and bushings in Air Insulated Substations are not needed with GIS. They have minimal radio and TV interference and also less erection time

However, Gas Insulated Substations suffer from a unique problem called Very Fast Transient Overvoltage (VFTO). VFTOs are a short-duration overvoltage in the frequency range of 100 kHz - 10MHz. Switching operations involving circuit breaker and disconnector can lead to rising of such VFTOs having a very short rise time followed by oscillations which may damage the system insulation and substation equipment. VFTOs typically have a magnitude between the range of 1.0 - 4.0 p.u., with rise times in the order of 3-100 nanoseconds, and frequency between 30kHz – 10MHz.

VFTOs originate mainly due to two reasons. Firstly due to switching conditions inside GIS substation like the operation of disconnectors, breakers, and earth switches. Secondly due to faults during onsite testing or in maintenance. VFTOs are classified into Internal VFTOs and External VFTOs. Internal VFTOs are mainly over-voltages or transients occurring between the GIS main conductor and the enclosure which imposes stress on GIS insulation. External VFTOs consist of over-voltages, and transient enclosure voltages i.e. transients appearing on the enclosure, secondary and adjacent equipment outside the GIS these may cause stress on secondary equipment and stress on adjacent high voltage equipment

There are four ways to mitigate VFTOs, using opening and closing resistors, using an R-C filter, Ferrite Rings, and Metal Oxide Arrestor. Using the opening and closing resistor weakens the reliability of the system and it should be equipped with actuator devices in the application, which operates frequently still the probability of failure is great. The R-C filter absorbs high-frequency components which consume the energy of VFTO, but the device R and C paralleled on the device cannot protect all the equipment, there are different selections of R and C for different types of equipment and different conditions, which would bring inconvenience of the installation. The Ferrite Rings are very effective in reducing the effect of VFTO also they do not increase the complexity of the structure of the GIS. The Metal Oxide Arrestor inhibits the amplitude of the VFTO but does not inhibit its steepness and high-frequency oscillation.

India’s Electric Vehicle Push will Lead to a Brighter, Greener Future

Kalyani Dhande, BE (Electrical) Div. B

(kalyanidhande360@gmail.com)                                                                 

India is the fifth largest car market in the world and has the potential to become one of the top three in the near future -with about 40 crore customers in need of mobility solutions by the year 2030. That is one side of the coin. The other side is that the country needs a transportation revolution. The current situation of adding ever more cars running on expensive imported fuel and cluttering up already overcrowded cities suffering from infrastructure bottlenecks and intense air pollution is unfeasible. India’s cities will choke. Though there is an ongoing debate regarding the generation of emissions due to the production of electricity to power electric vehicles. But those emissions levels are far lower than the pollution emitted by conventional vehicles and could be even lower as the electric power sector cleans up over the next few decades. The Environmental Assessment of a Full Electric Transportation Portfolio, by the Electric Power Research Institute, confirms that fuelling transportation through electricity instead of petroleum can significantly reduce emissions of greenhouse gasses and other air pollutants that threaten our environment and health. 

 

There's a low-carbon pathway with transportation electrification. Advancing policies that continue to clean up the grid and accelerate the adoption of electric vehicles will put us on the road to a clean energy future, and one that meets our climate goals. Drilling down to the impact on cars, plugging in will result in lower carbon pollution than a comparable conventional vehicle (CV). A PEV (Plug-In Electric Vehicle) today has 54 percent lower lifetime carbon pollution today. In 2050, the reduction could be larger, as much as 59 to 71 percent compared to a more efficient CV that achieves 48 miles per gallon in real-world driving, depending on the electricity grid carbon intensity electrification reduces harmful ground-level ozone, the principal component of smog because it lowers net emissions of nitrogen oxides and volatile organic compounds. A dominant factor in these reductions was the electrification of non-road equipment such as port cranes and cargo trucks, industrial forklifts, and equipment that services aircraft when they are not flying.

It would help India to fulfill its global commitments like the Paris goal, to reduce carbon emissions to limit global warming. It is likely to contribute to improving the overall energy security situation of India. Using EVs would help India save foreign exchange. The would develop a complete domestic supply chain and attract FDI(foreign direct investment) to the country. It is expected to play an important role in the local EV manufacturing industry for job creation. The battery manufacturing unit would make India’s EV path sustainable. Through several grid support services, EVs are expected to maintain secure and stable grid operations. Also, it would help in higher renewable energy penetration.

Transitioning our transportation sector from its near sole dependence on oil to electricity can lead to big reductions in carbon pollution along with improvements in air quality. Meeting long-range climate targets also require that we continue to clean up the electric sector. We must implement the Clean Power Plan and follow it with even stronger climate-protective policies. We can, and should, electrify transportation and further clean up the electric sector in parallel. Turning over the fleets of cars, trucks, and power plants to cleaner energy sources will take time and we should resolve to make sure it happens.
