Acknowledgement • I would like to thank Mr Narendra  Balkishan Soni (Head

of Department, Department of Electrical and Power Engineering, UPES) for meticulously planning academic curriculum in such a way that students are not only academically sound but also industry ready by including such industrial training patterns.

• I would also like to thanks Mr Ram Mohan Sharma (Group In-charge) for the positive attitude he showed for my work, always allowing me to question him and giving prompt replies for my uncertainties.

• Finally, I would also like to thanks Mr. Chandra Shekhar (Head-Simulator & Training), Mr. B.S. Prasad (Station Head) for giving us this opportunity and guiding during the course of the training.

Company Background• Rosa Power Plant is a 1200 MW (3*400 MW) of coal based

generation capacity at Rosa village in Shahjahanpur, Uttar Pradesh.

• Rosa Power Supply Company Limited (RPSCL), the holding company of Rosa Power Plant was incorporated on September 1, 1994 as a subsidiary of Aditya Birla Power Company.

• It was later transferred to Reliance Power on November 1, 2006 and is now fully owned subsidiary of Reliance Power. It is a project that has received a considerable support from the Uttar Pradesh government with it being designated a ‘Priority project’.

• The Entire power generated will be sold to Uttar Pradesh Power Corporation Limited (UPPCL).

About Reliance Power Ltd.

• Reliance Power Limited is part of the Reliance Anil Dhirubhai Ambani Group.

• It was established to develop, construct and operate power projects in the domestic and international markets. 

• Reliance Energy Limited, an Indian private sector power utility company along with the Anil Dhirubhai Ambani Group promotes Reliance Power.

• Along with its subsidiaries, it is presently developing 13 medium and large-sized power projects with a combined planned installed capacity of 33,480 MW.

• Reliance Natural Resources merged with Reliance Power in 2010, shortly after its initial public offering.

Overview of Industrial training• Simulator Training; The simulator training held for 6 days at RPSCL, Sahajhanpur

Uttar Pradesh.

Simulator is an imitation of the actual software that is being used to control a single unit.

Within these six days we have to complete simulation of 300 MW. which a single unit of entire RPSCL.

• Maintenance Training; Maintenance training held for 3 days.

This includes theory classes and plant visit respectively.

Switchyard, Turbine and Boiler drum mainly covered in this training.

Day 1-6 of Simulator Training

• Electrical Charging;This is a process of charging all the auxiliaries from the grid. In any Power Plant all your auxiliaries need to start first for that electric charging is done. All 6.6 KV, 415V, 220V DC, UPS & emergency power supply (DG) are available & buses are charged.220 KV-6.6KV-415V 

• Auxiliary Cooling Water;ACW pumps are started first followed by air compressor. Ensure that coal-handling system is ready. Ensure ash-handling system is ready for ash evacuation. Ensure that all soot blowers are in non -operating position. Start CW (Cooling Water) & CCW (Condensate Cooling Water) system and charge all the associated systems. Open drum, MS drain after stop valve & start up vents.

• Purging;Fulfil all the purge permissive and purge the boiler. Boiler purging will take exactly 300 seconds or 5 minutes. Carry out HFO and LDO leak test if required, otherwise bypass the test.

• Boiler Lighting;Light up the boiler with BC elevation and allow it to run for next 15 min. Take all the guns at BC elevation in service after 30 minutes & raise the drum pressure & temperature.

• Starting of Turbine;Start main Turbine oil, Jacking oil & Seal oil system. Charge hydrogen system and ensure that hydrogen pressure 3 bar. Charge Generator cooling water system with one pump in service. Start turbine barring gear RPM- 2.56. Ensure that all the HP-IP drains, valve chamber drains are open. Put AB elevation guns in service. Switch over the soot blowing medium from air to steam APH.

 • Seal Oil;Take second streams of ID & FD fans in service. Close HP/LP bypass. Regulate the pressure. Ensure all turbine drains are in open condition. Start seal Oil back up pump and check that the discharge pressure.

• Turbine Rolling;Rolling parameters achieved. Close all HP-LP bypasses. Bypass mode off then roll. Latch all Guide vanes (GV’s) & Transfer Vanes (TV’s). Set the target and ramp rate of i. 600 rpm, 100 ii. 2040 rpm, 100 iii. 2950 rpm, 100 and TV-GV transfer after that, iv. 3000 rpm, 50

 • Load Raising;Set the target load at 30 MW. Select the load rising rate of 1 MW/min. Start Primary Air fan. Start seal air fan. Light up the mill system. Take new mill in service & raise the firing rate. Now set target and change over at 40 MW.

• Synchronization;Open earth switch, close isolators. Check the readiness of generator. Exciter (ON), 20 KV.DEH-CNTL mode, auto sync, in service. Start synchronizing

• ISOLATOR; It is a disconnection switch to

be operated on no load. An isolator switch is used to

make sure that an electrical circuit can be completely de-energized for service or maintenance.

• Circuit Breaker; It is an automatically

operated electrical switch designed to protect an electrical circuit from damage caused by overcurrent or short circuit.

Conclusion• Industrial training has exposed the real working environment as an

engineer.

• Industrial training has developed/improved student creative and critical thinking as well as problem solving ability.

• Industrial training has exposed student with not only engineering related of works, but also management of works.

• Through practical training, I have gain a great learning to systematic work coordination in an environment that is conducive coupled with friendly staff that is always there to help.
