Project Summary

Research work proposes design and implementation of shunt type FACTS device for power quality improvement at distribution side. The device is named as D-STATCOM.
D-STATCOM is a power electronics device and is one of FACTS devices used to improve power quality by compensating reactive power on distribution side. It provides the real time bidirectional control of reactive power. Reactive power can be absorbed from and fed to the system to which it is connected. Which results decrease in voltage regulation i.e sags and swells and improved power factor. The construction of system is capable to recover the drop-in bus voltages due to lagging power factor.
Conventionally we use capacitor banks to provide the reactive power to the system and improve the voltage profile. These conventional compensations have limitations in the dynamic behavior. When we use them in heavy load levels, they’re helpful but for low load levels they provide more harm than good.
DSTATCOM is a shunt voltage source connect converter (VSC) which has been used in distribution networks to compensate the bus voltage so as to provide improved power factor and reactive power control.

Project Objectives

Research Objective and Approach:
1.    To Improve Voltage Profile.
2.    To provide the reactive power in order to improve the power factor.
3.    To integrate this device in real time system.
4.    To stabilize the voltage flickering at user end.
5.    To mitigate the issues that arises due to the non-linear loads.
6.    To provide voltage regulation at the load end and mitigate the voltage sag and swells.
7.    To design an economical device that is improving the distribution system stability and thus the power system stability.
8.    To covenant the load protection at user end.

Project Implementation Method

The proposed project will be implemented in the following phases:-

1. System modeling using Simulink/MATLAB Software. Distribution system with radial feeder technique will be developed.
2. Hardware implementation will be developed. A three phase rectifier, three phase inverter will be implemented independently. Instead of using standard rectifier and inverter modules, design of modules will be done by us. Also, the design and fabrication of control circuit board will be done.
3. In the last, proposed project will be integrated in existing real system.

Benefits of the Project

1. It will mitigate voltage sag in the distribution system.
2. It will mitigate voltage swell in the distribution system.
3. it will reduce harmonics.
4. It will improve power quality in the distribution system.
5. It will operate only when fault occur otherwise remains in standby mode.
6. It is very useful for distribution companies of Pakistan including LESCO, MEPCO, IESCO, GEPCO, FESCO, QESCO and K-electric by providing automatic voltage regulation.
7. Our work is also helpful in heavy industries to control power factor like Fatima Fertilizer Company, FFC, ENGRO etc.
