this paper presents a self-tuning pid (proportional and integral and derivative) controller for regulating terminal voltage synchronous generators. in order to modify the system reponse and to overcome the difficulties of self tuning controllers, a dual rate sampling control system was used. system results demonstrated usfulness of the proposed regulator. the designed controller is simple and c...

Abstract Wind power turbines have increasingly attracted attention as a renewable energy source. Gearboxes in wind reduce their efficiency, require periodic maintenance, and result gearbox failure. Consequently, direct-driven generators with high torque density emerged an alternative because they transmit the of turbine directly. Permanent-magnet vernier machines (PMVMs) possess simple robust s...

Accurate computing of the saturated inductances of Permanent Magnet Synchronous Machine (PMSM) is very important during the design process. In this paper, a new method is presented based on the B-H characteristic of the stator material and unsaturated inductances formulations. This method is used to calculate the saturated inductances of the axial flux PMSM. The synchronous inductance and all o...

Although synchronous generators are robust and long-lasting equipment of power plants, consistent electricity production depends on their health conditions. Static dynamic eccentricity faults among the prevalent that may have a costly effect. several methods been proposed in literature to detect static salient pole (SPSGs), they non-sensitive low degree failure require predefined threshold reco...
