Design of Adaptive controller for Regulating the Voltage by a Dynamic Voltage Restorer DVR

Abstract

Speedy changes in the source of power could influence the loads performance like (1) semiconductor invention factories (2) paper grindery (3) food treatment factories and (4) automotive installation factories. The prevalent troubles in the power sources are the decreasing of voltage (sags) or the increasing of voltage (swells) this could be caused by (1) upsets emerge in the transmission arrangement, (2) collapse of approach feeders and (3) fuse or breaker procedure. Voltage decreasing (sags) of Ten percent standing for five to ten cycles can cause an expensive loads damage. To relieve the low quality problems of power equipping, the modifier of voltage source could be connected by transmission lines serial which put as compensators. Which are called Dynamic Voltage Restorer (DVR). This research is suggesting a new blueprint for DVR controller by applying an adaptive neuro-fuzzy logic. As well as, the theory of instantaneous power is applied to estimate the voltage phase because of the great accuracy and low calculation for this theory. However, the results of simulation indicate the application of real-time on the suggested controller is powerful and potential comparison with traditional controllers which investigated previously.
