Abstract

Voltage sags is one of the most important for power quality problem that affect industrial customers. Generally, voltage sags are caused by fault in transmission and distribution system. Many of these industrial customers are suffered because of sag that affect the sensitive equipments. This project focused on the reactive power compensation for mitigating voltage sags. The main objective of this project is to design as well as to improve the level of voltage in the transmission system. First, the characteristic of reactive power compensation for compensating voltage sags are studied such as required shunt compensation current. The results of this project show that the shunt compensation current, injected reactive power decrease as impedance, where the source of impedance in parallel with the load impedance, increases. It also shows that reactive power compensation is the main requirement for voltage sags injecting by current source controlled. All the result are verified and simulated inPSCAD.
