5 Days Internship Programme on Solar PV Power Plant

The internship programme was of 5 days, conducted on a topic “Solar PV Power Plant” from 24th July to 28th July, 2019 at Ever Green Energy Technologies, Kochi. Theoretical sessions, Practical sessions, Simulation sessions, Designing sessions, Energy Auditing and other sessions were conducted along with Industrial Visits to Cochin International Airport Limited, Kochi and IGA Tech Industries, Kochi. It was organised by IEEE IA/IE/PELS Jt. Chapter Kerala in association with IGA Tech Industries and Ever Green Energy Technologies, Kochi.

The inauguration began auspiciously at 4.30pm with a silent prayer lasting for a minute. It was followed by reading out IEEE Code of Ethics by Mr. Sarath Chandran (Electronics Communication Coordinator, IEEE IA/IE/PELS Jt. Chapter Kerala). The welcome speech was delivered by Er. C M Varghese(Chair- Industry Relations Director, IEEE IA/IE/PELS Jt. Chapter Kerala). He had mentioned about the future of solar energy and the course details. The inauguration was done by Dr. Suresh Nair(Immediate Past Chair, IEEE Kerala Section), followed by lighting up the lamp. He explained about the importance of IEEE in the society and internship programmes. Mrs. Alice Antony (Managing Director, EGET) and Er. Anandhu S Kumar (Student Branch Coordinator, IEEE IA/IE/PELS Jt. Chapter Kerala) did the felicitation. Followed by that, Mr. Nebic J Johnson(Student Coordinator, IEEE IA/IE/PELS Jt. Chapter Kerala) led a membership development session on IEEE PELS, explaining member benefits, formation, activities and other details of IEEE and IEEE PELS. The inauguration was winded up by vote of thanks by Mr. Akhilesh Vishnu T I (Design Lead, IEEE IA/IE/PELS Jt. Chapter Kerala). Non-IEEE delegates from Providence College of Engineering Chengannur have decided to form a Student Branch and a PELS Student Branch Chapter in their institution.

The registration was started at 9.30am and lasted for 1 hour. The event started with a session by Er. C M Varghese (CEO, EGET) on the basics of solar system and PV Power Plant as the morning session with having a tea break in between. After 1.15pm, lunch was given to delegates. The afternoon session was led by C M Varughese wherein the delegates were familiarised with the different instruments used in a Solar PV Power Plant. The delegates were taught to measure the specified quantities and the calculations based on it. Followed by that, inauguration of the event was conducted.

The day started with a session led by Dr. Nikhil P G(Former Scientist, National Institute of Solar Energy). He explained various aspects used in Solar PV Power Plant and did some group activities. The delegates were divided into 5 groups having 5 people as strength. They were given tasks to study a given case study happened once in the world and asked to made a chat presentation on that. Groups were restructured in such a way that each person in each group understood the problem and solution in each case. After tea break, delegates were taught to design a solar power plant for their home. Each of them designed one solar power plant as per their house’s requirement. They were taught to calculate the profit they would gain after installing plant at the house. Commercial designing were also done. After designing, a theoretical session on Types and Selection of PVs and Inverter is led by Sudev D. After leaving for lunch, practical session on types and Selection of PVs and Inverter was done. The day was ended up with simulation session, conducted using PVsyst software. 

The day 3 started with the familiarisation of parts of Solar PV Power Plant by Sudev D. The delegates were divided into several groups for the familiarisation sessions. A session on safety and precaution measures to be undertaken at site while working in a Solar PV Power Plant personally as well as on dealing with the equipments were taken by Annie James. The afternoon session was handled by C M Varughese wherein the delegates were asked to identify the familiarised parts of a Solar PV Power Plant and arrange it in a required manner. The day 3 was ended up with a session on the various types and sizing of Solar batteries.   

The day 4 started with the first phase of the Industrial Visit to Cochin International Airport Limited, the first fully solar powered airport in the world, wherein all the delegates were overwhelmed with a panoramic view of a 14.4 MW ground mounted, grid connected photovoltaic power station. An overview of the details of the project were given. The daily data estimations with the help of SCADA monitoring were clearly explained along with the total output energy, weather forecasting data, plant performance data and many more. The delegates were given a clear cut idea of the operations involved in  monocrystalline modules, string inverter, SMPS and the connections of the string type photovoltaic cells installed in CIAL. They were able to observe the various pyranometers placed at different places of the plant.

Followed by the views of the terminals of CIAL, the delegates were taken to second phase of the Industrial Visit to IGA TECH Industries Ltd. Kochi, a well-known industry in the field of Power Electronics and Industrial Automation and a has made a name for itself in the list of top suppliers of Inverters and UPS Equipments. Owing to the keen interest of the delegates to explore the manufacturing of inverters, the instructors monitored, starting from the assembling and soldering of power electronic devices, which was followed by the testing of the circuitry, internal connection diagrams of the inverters and the mounting of the chasis and casings.

After the completion of the Industrial Visit, the delegates were taken back to Ever Green Energy Technologies Ltd. Kochi for the lunch. After lunch, a practical session on Solar Installation and commissioning was led by Akhil(Solar Consultant, Kochi Metro). The day 4 ended up with a practical session by Sudev D, on the operations and maintenance of Solar PV Power Plant installed there.

The day 5 started with the session on Energy Auditing, Site study and optimisation technique by G. Krishnakumar. The different aspects involved in the various levels of energy auditing were well explained with PowerPoint presentations. The stages included in energy auditing of a site and its optimization techniques were also described in a well clearly manner. The delegates were taught to analyse the different levels of reports and costs effectiveness on Energy audits. The session was followed by a test which included general areas of interests in interviews and the topics covered in the whole internship. The day 5 got soon ended up with lunch since a majority of the delegates have to travel a long distance to reach their places.
