INDUSTRIAL VISIT TO SRISAILAM HYDRO ELECTRIC POWER STATION
INDUSTRIAL VISIT TO SRISAILAM HYDRO ELECTRIC POWER STATION
IEEE Power Electronics Society (PELS), Vehicular technology society(VTS), Power Energy Society(PES), and Sensors Council have collaborated to conduct an industrial visit to Srisailam hydroelectric power plant on 6th Aug 2023 for both fourth-year students of the electrical and electronics department of Rajeev Gandhi Memorial College of Engineering and Technology(RGMCET).
A total of 90 students took part in this Industrial tour and made it successful under the guidance of 4 faculty members of Rajeev Gandhi memorial college of Engineering and Technology. We reached the power plant by 11:00 am and visited the control room which has been converted from manual to complete automation after the power plant was affected by the heavy floods. K. Swathi Lakshmi, AE who is an alumnus of Rajeev Gandhi memorial college of Engineering and Technology has accompanied us
There are 2 banks of the hydropower plant we visited the right bank which belongs to Andhra Pradesh. It consists of 7 units each generating 110MW of power total it generates 770 MW of power. The operation of a power plant depends upon the demand. Here if the height should be more than or equal to 834 m height to generate more electrical energy all 7 units can be controlled in this control room by using systems that are operated automatically. Here the water from the dam flows through the penstock and strikes the turbine blades and the kinetic energy is further converted and the water is left from the tail race again back to the river. Here thyristor-based power electronics devices are used to provide field excitation to generate EMF and the 11KV is generated and it is sent to the step-up transformer and voltage is stepped up and further it is transferred to the power grid through the bus bars. Here bus bars have a voltage with a difference of 5V. The frequency of the motor is constant i.e. 50Hz and the speed is around 180 rpm. We can control the equipment through this room this room consists of 7 relays and circuit breakers one for each unit if any fault occurs in any of the units we can hear an alarm sound so that we can rectify the fault with the help of the system if even the fault is not rectified it immediately trips and we can later on observe where the fault is occurred and the reason of the fault manually. There are huge cranes to lift the equipment in case of any maintenance.
The event was a great success and the attendees appreciated our efforts in organizing such an informative and useful event.
