The Power Station
is located on the downstream of the Chibro
Power station and was commissioned in the year 1984. The power station
draws water through a 6 km long and 7.5 diameter tunnel directly from
the collection gallery of the Chibro power
station. The surface Power House comprising 4 units of 30
MW each with Francis turbines of 43,600 HP output is located on the
banks of Yamuna and the outlet of the water
from the power station is in river Yamuna
upstream of the Dakpathar Barrage. The Power
Station's Design Energy is 345 MU with a design head of 57.9 m.
The operation of Chibro power station and the
Khodri power station is another engineering
marvel. The tandem control scheme between Chibro
and Khodri Power Stations is in operation
since January, 1984 and is the first of its kind in the country which
optimizes the utilization of water for generation besides maintaining
the safety of both the plants in case of outages.
The plants downtime has reduced and the availability has improved
significantly. The improvements have been possible due to the number of
maintenance and safety measures under taken which were pending since a
long time. The APDP also provided funds for the modernization in a
limited way mainly for installation of
(i) Static Excitation System
(ii) Dry Type Auxiliary Transformers and
(iii) SF6 Breakers .
The major
maintenance works undertaken in the plant that has been responsible for
improved performance are:-
i) Repair of underwater parts.
ii) Epoxy Textolite wedges and packers
were provided in the stator punching.
iii) Replacement of old
governors with Micro-processor based Governors
UJVNL proposes to carry out the M&U of the power station which is estimated
to cost Rs. 120.00 crore.
The major M&U works proposed are:-
i) Provision of On-line
monitoring equipment.
ii) Digital display of parameters in control room.
iii) Modernization of Communication, Test & Control,
Protection, Instrumentation and fire protection of generators
iv) Improvement in the efficiency of generators and Turbines.
v) Fire fighting system
The M&U works besides enhancing the life of plant by another 25
years would also increase the generation to 400 MU. The works are
expected to be completed by 2011-12.
