Bharat Heavy Electricals Ltd has achieved a major
milestone with the successful manufacture and testing
of the country's first large capacity new series Turbo
Generator of 600-mw rating. The state-of-the-art generator
shall be supplied and installed at the upcoming North Chennai
Thermal Power Project of Tamil Nadu Electricity Board, a
release by BHEL said.
In addition to sub-critical thermal power plants of 600-mw
rating, these new series generators shall also cater to the
requirements of thermal power stations with supercritical
turbines of 660-mw and 700-mw ratings, the statement added.
With the successful testing of the generator, a new
benchmark has been set by BHEL with respect to
indigenous manufacture of thermal sets with
supercritical parameters. Several sets of 600 mw,
660 mw, 700 mw and 800 mw ratings are currently under
various stages of manufacture at BHEL's Haridwar plant.
The facility for assembly and testing of this series of
generators has been designed and engineered in-house at
BHEL's Haridwar plant in Uttarakhand. The new facility has
the capability to manufacture and test turbo generators of up
to 1,000-mw rating and has test pits for assembly of two
generators simultaneously.
The test facility is equipped with special 12-mw drive
motors powered from a variable frequency drive system
and to validate generator performance parameters, opencircuit
and short-circuit tests can be conducted during
testing. State-of-the-art data acquisition for
logging of test data and an integrated
control and monitoring system are other
significant features of this facility. The test station has
large video screens wherein engineers can monitor real
time data during testing. This multi-level test-bed
includes complete set of auxiliary equipment like lube oil,
seal oil, primary water, hydrogen gas, auxiliary cooling
water supply systems and associated controls, an official
release of BHEL observed.
