Industrial Visit to Rajasthan Rajya Vidyut Prasaran Nigam Limited 220 KV Grid Sub Station

  • Brief Report of Industrial Visit on 03.03.2015

  • RRVPNL 220 KV GSS SEZ-I, Jaipur

  • The students of EE & ECE were visited Rajasthan Rajya Vidhut Prasaran Nigm Limited, 220 KV Grid Sub- Station (GSS) on 03.03.2015.This GSS is near a village Kalwara, Mahindra World City, SEZ-I, Distt. Jaipur.The RRVPNL is a state Government Company. The students are observed some points at GSS as following:-
  • The Key points are :-
  • "The capacity of the GSS is 220KV/132KV step-down GSS"
  • "Two inverters are used for converting to DC to AC voltage and power of each Inverter s 500MW and 3 phase output with frequency of 50 HZ."
  • "In that power plants during the day some of the energy they generating was being used by themselves and supply to JVVNL"
  • "We have seen current transformer (800A/1A) which is used for measurement of operating plant current"
  • "Potential transformer (220KV/110V) is used to measure plant operating voltage on both sides"
  • "GSS is connected to PGCIL Heerapura 400 kv station by mesh connection"
  • "Students have learned various type of protection relays e.g. over voltage relay, over current relay, distance relays, auxiliary relay etc"
  • "Wave trapper is used to communicate signals to control room"
  • "Lightening arrestor is used to protect the electrical equipments from over voltage produced by thunderstorm."
  • We are attached some photograph during visit:

  • Finally, I would like to thank all higher authorities and administration of Pratap University for giving us permission because without your kind support trip could not be a successful trip. I would like to thank all students for maintaining interest and discipline during both visits. In future our department will try to continue this practice so the students get benefited with industrial exposure with the academics.
