3. Problem Statement
• Improvement of Power System Stability
• Reactive Power Compensation of line
• Non-linear nature of Power System
• Conventional Controllers like PID deal only with linear
systems
• Limitations due to linear nature (e.g. response speed
etc.)

8. Applications
• STATCOM is installed to support electrical networks
that have a poor voltage regulation
• STATCOM with appropriate controller can be very
effective in harmonic reduction
• STATCOM can improve the bus voltage so as to make
the desired amount of power through the transmission
line

12. Hardware Developed
• We have made a Single Phase Inverter at 230V RMS
for 1kVA load using IGBT “IRG4BC30FD” using
isolated DC supplies.
• The amplitude, frequency and phase of output voltage
have been controlled using microcontroller
“STM32F401 Discovery”
• We have employed a LC filter to filter sine wave from
carrier wave as well as for isolation with grid supply

15. Future Deliverables
• We are currently working on synchronizing the inverter
with the grid
• We are currently working on the control of inverter
using Neuro Fuzzy Control
• In the near future we will test the circuit by giving PQ
demand of our own choice
