Permission was accorded for Third Year EEE and Final Year EEE Students to NLC India Ltd. at Neyveli On 18.10.2019, 49 students visited the industry. Students got exposure towards,

• Lignite Mining.
• Thermal Power Generation.
• Solar / Wind Energy Generation.
• Coal Mining.
• Organic/Bio Farming.
• Herbal Plantations/Gardens.

The following faculty accompanied the Students for the Industrial Visit,

• Mrs.S.L.Sreedevi,Assistant Professor-EEE
• Mr.Tamilamuthan,Assistant Professor-EEE
• Ms. Abirami,Assistant Professor-EEE
• Mrs. Joshlin,Assistant Professor-EEE

The industrial visit is associated by EEE staffs Mrs.S.L.Sreedevi , Mr.Tamilamuthan , Ms. Abirami and Mrs. Joshlin - of PERI IT. Junior Engineer Mr. Krishna gave a detailed explanation about the site and the on-going process in the plant.

NLC COOLER

The 1470 MW Second Thermal Power Station consists of 7 units of 210 MW each. In February 1978, Government of India sanctioned the Second Thermal Power Station of 630 MW capacity (3 X 210 MW) and in Feb.'83, Government of India sanctioned the Second Thermal Power Station Expansion from 630 MW to 1470 MW with addition of 4 units of 210 MW each. The first 210 MW unit was synchronised in March 1986 and the last unit (Unit-VII) was synchronized in June'93. The power generated from Second Thermal Power Station after meeting the needs of Second Mine is shared by the Southern States viz., Tamil Nadu, Kerala, Karnataka, Andhra Pradesh and Union Territory of Pondicherry.

NLC PLANT VIEW

In NLC, the Junior Engineer Mr. Krishna gave a detailed explanation about the site and the on-going process in the plant. The installed plant capacity is 2,740 MW. The plant receives the coal from Mines 1 and Mines 2 in Neyveli. The coal used is lignite which has more amount of ash content. The coal is transported through belt conveyor before getting it to the boilers. Students had a look at the pre heating process and the types of fans used for the cooling process. The plant engineers also explained about ash handling and ash filtration processes. The exhaust gases and the fly ash are passed through a chimney constructed at a standard height of about 275 m. The super heated steam (540°C) is sent to the turbine of 3 types: high pressure turbine, medium pressure turbine and low pressure turbine. Turbo alternator is present on the same shaft where turbine is present. Turbo alternator runs at a rated speed of 3000 rpm. The overall process is monitored and controlled by PLC programs. The power produced is then connected to the power grid through switch yards. Switch yard is comprised of circuit breakers, isolators and step up transformers. Switching transformers are used during emergency times (plant shut down) to get power from the nearby power station. The communication is done using wave-traps in the power line.
