Special Purpose Application
in Industries :
Industries having fast variable loads like spot
welders, arc welders, CNC machines, cranes, hoists,
steel rolling mills, steel forging industries
etc. have real problem of maintaining desired
P.F. level. A few systems have already been supplied
for these special applications.
P.F. correction at water and sewage pumping stations
using 3.3.KV and 6.6 KV motors is practically
an untouched area. We have studied about six water
pumping stations of Delhi Jal Board using such
motors. P.F. at all such places is between 0.72
to 0.8. The Maximum Demand at such stations is
average 4000 KV A. M/S Reliance and TATA have
exclusive power distribution rights in Delhi Metro
area. Both of these companies have stopped billing
the electricity consumption on KWH basis, more
commonly known as on unit basis. As per the new
policy, now the billing is on KV AH basis. This
is a proven fact that under such circumstances
the billing can be reduced by average 25 % if
the P.F. is improved to unity from the actual
values mentioned above.
It can be realized that this area has a huge market
potential, if we can manage proper publicity and
convince various government agencies about the
savings.
This same billing pattern has already been introduced
by UP electricity board. The concept of directly
working at 3.3 KV or 6.6 KV level is our own and
there is no body else in this field.
Our system can very effectively be used at power
distribution sub-stations of state electricity
boards. We have studied a power distribution station
at Connaught Place, Delhi, which transfers the
voltage from 33KV to 11KV. The average P.F.
at this place is 0.72. It can be easily be calculated
that a huge power saving to the tune of more than
25% can be achieved only by improving P.F. from
the present value of 0.72 to 0.0.98. The sub-station
maximum demand is about 16 MVA. This market is
yet to be properly studied. It is a fact that
we can easily add about 20 % to our existing power
generating capacity merely by improving P.F. at
suitable stages. The requirement of our system
is huge and without any competition. All electricity
boards in India use fixed capacitor banks at their
sub-stations which, in fact cause more harm. We
have already supplied two small systems to Surat
Electric Company at their distribution sub - stations
which is giving good results with a pay back period
of less than twelve months.
Another potential market for our product is Wind
Electric generators. There is a huge demand by
the manufacturers and in this field we can work
virtually without any competition. Following are
three major manufacturers of wind Electric Generators
in India;
1. M/S Suzlon.
2. M/S Vestas.
3. M/S Enercon.
We have already approached
M/S Suzlon and the negotiations are at very advance
stage. They have indicated that the final decision
may be taken by the end of February 2005.
The last area which we intend to penetrate is
Railways. Traction sub stations and railway work
shops of all railways through out India are paying
heavy penalties on account of low power factor.
We have been studying railways since last three
years. It is an acute problem and till date, no
body has been able provide any economically viable
solution.
After carrying out studies at a number of places
we took up a job (as joint venture with and another
financially sound company) of improving P.F. at
Parel work shop of Central railway. We designed,
manufactured and commissioned a system of 2150
KV AR in the month of March 2004 which is working
satisfactorily till date. We could achieve reduction
in the maximum demand by about 1000 KV A.
It is a great saving for railways and for the
nation. In this case alone it can be proved that,
the electric supply company can supply power to
other consumers to the tune of 1000 KV AR without
spending even a single Rupee for either augmentation
or strengthening the generating or transmission
and distribution capacity. We have already take-up
study of Western Railway repair work shop at Lower
Parel and expecting the order before March 2005..
This example proves that working with poor power
factor is a criminal national loss, which must
be avoided. Here it is worth pointing out that
we were the first agency to carry out this job
for any Indian railway work shop in India.
Similarly most of the traction sub-stations in
India of Indian railways suffer heavily due to
low power factor. It is an inherent characteristic
of the locomotives that their P.F. is very low.
We had carried out a power analysis study At Bhadli
Sub-station near Jalgaon in Maharashtra. It can
be very well seen that the system P.F. is as low
as 0.72. The analysis report is attached herewith.
Till now there was no solution available in India.
We have taken up this job and the project is near
completion.
At present we have only M/S ABB ltd as our competitors.
But the market is huge and can absorb a number
of such manufacturers. We also feel that our technology
is much superior technically and economically
in comparison to that of ABB. More over our technology
has been proved in railways at Parel work shop,
where as M/S ABB do not have any such proof
