Real-time implementation of power theory using FLC based shunt active filter with different fuzzy M.F.s

In this paper the shunt active filter (SHAF) is used to improve the power quality of the electrical network by mitigating the harmonics with the help of different fuzzy membership functions (M.F.s). The proposed SHAF with different fuzzy M.F.s is able to eliminate the uncertainty in the system. On the other side fuzzy logic controller (FLC) has widened its applicability to many engineering fields and offer satisfactory results for a wide variety of operating conditions. It helps in fulfilling the need of perfection, such as stability and robustness to every system. All this motivated to adopt fuzzy logic controller for SHAF applications. By using different fuzzy M.F.s, SHAF gains outstanding compensation abilities. To validate the proposed approach, the system is implemented on a real time digital simulator and adequate results are reported for its verifications.
