PROFESSIONAL EXPERIENCE
Total
37 years (May 1978- Sep 2015), Worked at Electronics division BHEL Bangalore in
engineering department and worked on electronic cards, power electronics, control
system, traction, power factor, reactive power, SVC, HVDC, thyristor control,
series compensator, flicker and unbalance load control for ARC furnace Harmonic
filter analysis, traction control for electric train etc.
MAJOR PRODUCT/ PROJECT COMPLETED
1. Design of Control
circuits for speed control of the D.C. Motor using Thyristor. Final year
B.Tech. Project.
2. Design of Solid State
Reactive Power Factor controller for capacitor switching. New product to BHEL.
1. Solid State alarm annunciator.
New product to BHEL.
2. Design of logic
modules, delay modules etc.
4. Pulse width modulator
based G.T.O. Controlled regulator for speed control of the motors/voltage
control .New product to BHEL (1983-84)
5. Sequence controller
for 11 KV Static VAR Compensator (SVC).
This equipment is used
in SVC systems to switch ON/OFF automatically various equipments in desired
sequence.
6. Development of Base
electronic panel for NHVDC project, first time in India. (New technology)
8. Development of the
Valve Electronics for NHVDC project, First time in India (New Technology).
9. Design of the Base electronics
and Valve mini simulator
10. Design of 3Kv inpulse
generator New product to BHEL
11. Controller for SVC
system suitable for balanced load for Vaizag steel plant.
12. Development of controller for SVC system
suitable for unbalanced load for Alloy steel plant Durgapur. First time in
India. New product to BHEL.
13. Development of the
controller for SVC system suitable for AC Arc Furnace application. First time in India (New product to
BHEL).
The electric arc furnace
is used in steel plants to melt scraps. The furnace creates problems like
unbalance in power system, harmonics, flicker etc. To contain these problems,
SVC is used. The controller so designed is one of the equipment required in the
SVC system. The controller is used to control P.F., unbalance and flicker
automatically in system with the help of thyristor-controlled reactor. In one
of the project this controller is used to control 100MVAR reactor in 220KV
system.
This controller was developed
at the cost of 15L, which avoided importing of controller costing about more
than 2 Crores. This controller was a big projects and
required numbers of PCB development.
14. Development of
controller for SVC system for DC ARC FURNACE. New product to BHEL
This product is used for
SVC system required in DC arc furnace type load. The controller designed in
this project will control thyristor-controlled reactor, which helps in
controlling P.F. and voltage fluctuation in the power system.
15. Design of 7 kV Impulse
generator for capacitive load. New product to BHEL
This impulse generator
is used to apply switching inpulse across capacitive load. The generator can
provide variable output up to 7KV.
16. Development of
controller for Controlled shunt reactor (First time in India) New product to
BHEL
Controlled shunt reactor
(CSR) is basically high impedance transformer. Impedance of the transformer can
be controlled using thyristor switches. It is possible to control the voltage
and P.F. of the line by connecting CSR across the line. The controller will
measure various parameter of the line and control the CSR to improve
voltage/P.F. profile.
17. Development of controller for Flexible AC
transmission system (FACT) First time in India New product to BHEL (Part time only)
18. EMTP system study for
harmonics for high current (12kA to 55kA) rectifier for 3 contracts.
19. Power factor
improvement for the industrial LT loads.
20. Number of electronic
modules was developed for above projects.
