2) The Ministry of Power has recently said that 17 new Islanding schemes have been planned for the major cities besides already existing 26 schemes. In this context, consider the following statements:

  1. Islanding is the intentional isolation of a part of power system during external widespread grid disturbance.
  2. Islanding Scheme ensures the maintenance of essential services and also faster restoration of supply to the electricity consumers in the event of any outage. 

Which of the statement(s) given above is/are correct?

  • a. 
  • b. 
  • c. 
  • d. 
Answer : c

Islanding

  • Islanding is the intentional isolation of a part of power system during external widespread grid disturbance. 
  • This isolated part of Grid is called Island.
  • Such a disturbance may lead to black out.

Islanding Scheme

  • Resilience of the electricity grid is very important particularly in restoration of supply in the event of the major power outage.
  • Therefore, Islanding scheme provides a mean to continue to supply power to the essential services in a zone or area.
  • Islanding Scheme is a defense mechanism for the power system in which a part of the system is islanded from a disturbed grid so that this subpart could survive in isolation from rest of grid and continuity of supply to the essential load in this area is maintained.
  • In such electrical Islanded system, the essential loads should be identified and covered so that these load continue to be served even during any major outage.
  • As informed by Central Electricity Authority (CEA), 17 numbers of new Islanding schemes have been planned for the major cities besides already 26 existing/under implementation scheme in India.

Which of the statement(s) given above is/are correct?

  • a. 
  • b. 
  • c. 
  • d. 
Answer : d

Rain at Greenland Summit

  • For the 1st time on record, the summit of Greenland received rain and not snow, just as temperatures at the spot went above freezing for the 3rd time in less than 10 years.
  • This was the heaviest rainfall that the Greenland received since record keeping began in 1950.
  • Greenland is the world’s largest island between the Arctic and Atlantic Oceans.
  • Three-quarters of its surface is covered with a permanent ice sheet.
  • At the highest point on Greenland’s ice sheet, the US’s National Science Foundation maintains a Summit Station, a research facility that observes changes occurring over the island as well as in Arctic weather.
  • The research facility observed rain at the normally frigid summit, with the precipitation extending up to Greeland’s southeast coast.
  • Not only is water warmer than the usual snow, it's also darker - so it absorbs more sunlight rather than reflecting it away.
  • Rain & high temperatures triggered extensive melting here, which is 7 times more than daily average observed at this time (August) of the year.
  • Rapid ice melting will be running off into the ocean in volumes, thus accelerating global sea level rise.
  • Concern - The UN’s “code red” climate report concluded that the burning of fossil fuels led to Greenland melting in the last 20 years.
  • Arctic Ocean may witness ice-free summers by 2050 due to extreme climate interventions.
  • If that happens, sea levels could rise by 20 feet, threatening low-lying cities around the world such as Mumbai, New York, etc.
  • Rapid melting is also threatening polar bears, which have to make their way towards Greenland’s interior from the coasts, where they usually find enough food.
