A Review on Power Quality Problems, Causes and Mitigation Techniques

The quality of electrical power always remains a key concern especially with the increasing growth of sensitive and advanced loads in a present distribution system. Many of the electrical equipment or device may react adversely and distinctly as with the severity of power quality problems. Perhaps, the major equipment failure may be resulted due to these critical power quality problems. Moreover, it is also critical for the health of all the electrical appliance and devices incorporated in the present days power distribution networks. This paper represents a comprehensive review of all these power quality challenges comprising their importance, causes, classification, and mitigation techniques usually adopted in a modern power system. The nature and characteristics of these power quality issues are articulated with an intention to mitigate them in a more effective and efficient manner.
