Professor of SASTRA University Thanjavur,
Muralisachithanadam, wrote to me about his lecture on Pumped storage power
plant posted in YouTube... on the notes taken from my blog. I was really happy
when he mailed me more than couple of emails to let me watch the lecture… I was
quite out of idea when I wrote about the Pumped storage power plant? But it
seems I have been writing about it indirectly through my post on Kadamparai Dam
in Valparai.
The professor narrates the subject simply
to understand anyone in Tamil and I am so grateful for his note of thanks and
picture on me at the end of his lecture (video below). Kadamparai power project is an
engineering marvel and manmade wonder! The unique about this hydro power
project was the power plant is situated deep inside the hill, travelling 6km into
a tunnel that cut through a single mountain rock. I have nothing to say rather
feeling wonder, how incredible our engineers are to make successful a project
design that borrowed from Germany which failed at the level of execution and
operation there.
I
visited the Kadamparai site in 2008, but we couldn’t get permission to go
inside the tunnel to visit the power house which is 7 storeys inside the
tunnel! I was happy at least getting chance to make visit to the site and
learning its amazing process. The power generated here were in two modes: In
the generation mode, the machines will be operated to cater the peak hour
demand for full load, depending on the storage level of Kadamparai Dam and the
Upper Aliyar Dam. In the Pump Mode, the machines will pump the water from Upper
Aliyar Dam to Kadamparai Dam during night hours on grid frequency above 49.4 Hz
and heavy under drawl of UI from central pool.
I really thank the professor for making
an impression among students about the Pumped storage power plant and
encouraging them to take notes from my blog. The Kadamparai pumped storage power
plant is a marvelous project that not many know about its efficiency (even not
many engineers aware of it) which is first of its kind in India. It is also one
of the highly protected sites, surrounded by wildlife activities and tribal
settlement and getting permission is toughest… even if not visited, leaning about
this project is must.
