Abstract
With the development of high technology industries, the requirements for power quality become strict. The conventional approach to ensure the continuous supply of high quality power to sensitive loads is to use uninterruptible power supplies (UPS). However, this equipment is costly and batteries require maintenance. Consequently, this thesis presents a more economic solution to this problem, that is, the usage of Dynamic Voltage Regulator (DVR). By using Dynamic Voltage Regulator, the goal to regulate unbalanced distribution system voltage can be achieved.
Traditional DVR can be applied to regulate bus voltage and improve unbalance in a distribution system. Usually, pure reactive power compensation is adopted. The use of real power compensation is rare. In this thesis , a new method which employ real power compensation as well as reactive power compensation is presented for the design of a DVR. The effectiveness of the proposed DVR is compared with traditional DVRs which employ only reactive power compensation. Simulation and experiments are conducted in order to demonstrate the feasibility of the proposed algorithm. compensation capability and losses are the proposed DVR are evaluated based on simulation and experimental results. From the simulation and experimental results, it is concluded that bus voltage cab be regulated by the proposed DVR with minimum injection voltage and minimum capacity.
