Electrical energy is the most Efficient and enormous of energy and all of us are desperately dependent on the electric supply. We cannot imagine the life without supply of electricity. At the same time the quality and persistence of electric power supplied is also very important for the efficient functioning of the end user equipment. Most of the commercial and industrial loads demand high quality uninterrupted power. Thus maintaining the qualitative power is of important.

Power Quality Enhancement Using Custom Power Devices considers the structure, control and performance of series compensating DVR, the shunt DSTATCOM and the shunt with series UPQC for power quality improvement in electricity distribution. Also addressed are other power electronic devices for improving power quality in Solid State Transfer Switches and Fault Current Limiters. Applications for these technologies as they relate to compensating busses supplied by a weak line and for distributed generation connections in rural networks, are included. In depth treatment of inverters to achieve voltage support, voltage balancing, harmonic suppression and transient suppression in realistic network environments are also covered. New material on the potential for shunt and series compensation which emphasizes the importance of control design has been introduced.

Voltage sags and harmonics disturb the power quality and this can be overcome by custom power device called Dynamic Voltage Restorer (DVR). The DVR is normally connected between the source or feeder and critical or sensitive load. The performance of DVR depends on the efficiency of the control technique involved in reference signal generation considering phase angle jumps. The control technique shall compensate the voltage disturbances and shall reject the load current disturbance. If voltage regulation is high, disturbance rejection ability decrease and vice versa Hence a robust and optimal control technique is very much required to compromise between voltage regulation and disturbance rejection. The work is focuses on implementation of various control techniques with suitable voltage source converter topology for proper voltage regulation and disturbance rejection.

This thesis describes the problem of voltage sags and swells and its severe impact on non linear loads or sensitive loads. The dynamic voltage restorer (DVR) has become popular as a cost effective solution for the protection of sensitive loads from voltage sags and swells. The control of the compensation voltages in DVR based on dqo algorithm is discussed. It first analyzes the power circuit of a DVR system in order to come up with appropriate control limitations and control targets for the compensation voltage control. Simulation results carried out by Matlab/Simulink verify the performance of the proposed method.

Power quality problems have increasingly become a substantial concern over the last decade, but surprisingly few analytical techniques have been developed to overcome these disturbances in system-equipment interactions. Now in this comprehensive book, power engineers and students can find the theoretical background necessary for understanding how to analyze, predict, and mitigate the two most severe power disturbances: voltage sags and interruptions. This is the first book to offer in-depth analysis of voltage sags and interruptions and to show how to apply mathematical techniques for practical solutions to these disturbances. From UNDERSTANDING AND SOLVING POWER QUALITY PROBLEMS you will gain important insights into Various types of power quality phenomena and power quality standards Current methods for power system reliability evaluation Origins of voltage sags and interruptions Essential analysis of voltage sags for characterization and prediction of equipment behavior and stochastic prediction Mitigation methods against voltage sags and interruptions Sponsored by: IEEE Power Electronics Society, IEEE Industry Applications Society, IEEE Power Engineering Society.

Among most severe power system disturbances those degrading power quality are voltage sags and transient interruptions. Even voltage sags lasting only a few tens of milliseconds are enough to bring entire production lines to standstill, causing considerable economic damage as well as endangering the production equipment. Therefore necessary measures have to be taken to protect sensitive loads which are susceptible to these voltage disturbances. Among the solution candidates such as, Uninterruptible Power Supplies, Motor-Generator Sets, etc, Dynamic Voltage Restorer (DVR) which is an effective custom power device has been proposed to mitigate such bus voltage sags on sensitive loads with its excellent dynamic performance. In this study, load side connected shunt converter topology was chosen for the implementation of DVR. The performance DVR was tried to be improved by improving the control strategy used. Super Film located in Gaziantep which is one of the SANKO subsidiary company was chosen to simulate the operation of DVR as actual case of Turkish industry. All the simulations in this study were carried on PSCAD/EMTDC Software.
