The purpose of this paper is to present a new approach based on the Least Squares Error method for estimating the unknown parameters of the nonlinear 3rd order synchronous generator model. The proposed method uses the mathematical relationships between the machine parameters and on-line input/output measurements to estimate the parameters of the nonlinear state space model. The field voltage is...

In this paper, we propose a new optimized PID controller to stabilize the synchronous machine connected to an infinite bus. The model for the synchronous machine is 4-ordered linear Philips-Heffron synchronous machine. In this research, the parameters of the PID controller are optimally achieved by minimizing a definite fitness function to removes the unstable Eigen-value to the left side of im...

OBJECTIVE/HYPOTHESIS The objectives were to test the hypothesis that synchronous contraction of the thyrohyoid muscle by electrical stimulation during swallowing would improve dysphagia resulting from reduced laryngeal elevation and to evaluate the effectiveness of the synchronous electrical stimulator. STUDY DESIGN Prospective study. METHODS Eleven male and 12 female patients (age range, 3...

One of the ways generating electrical power from wind energy is by employing promising technology permanent magnet synchronous generator (PMSG) variable speed turbine (VSWT). With daily increase and integration farms into traditional grids, it imperative to carry out transient stability studies generators in farms, order fulfill operational grid codes. To solve intricacies posed stochastic natu...

Wind power is experiencing steady growth, and wind turbine technologies are continually developing. Currently, power ratings of up to 20 MW are being considered for future wind farms. Offshore applications, which call for the largest and most powerful wind turbines, demand a higher standard of reliability and maintainability. Because they offer better overall efficiencies and higher reliability...

This work presents a methodology, based on the modeling of an electrical power system test created in PSCAD/EMTDC simulation environment. The purpose is to evaluate, at first, impacts that Thyristor Controlled Series Compensator (TCSC) and Static Var (SVC) cause transient angular stability generators against disturbances, evaluating rotor displacement synchronous under analysis. In second momen...

This paper studies the use of the PMSM (permanent magnet synchronous machine) generators instead of the induction based alternating current generators in renewable energy sources (wind turbines, combined heat and power, etc.). The paper considers the most significant advantages of the novel permanent magnet technology such as increased specific power, high torque, reduced maintenance costs, inc...

High voltage generators are being subject to higher voltage rating and are being designed to operate in harsh conditions. Stator windings are the main component of generators in which Electrical, magnetical and thermal stresses remain major failures for insulation degradation accelerated aging. A large number of generators failed due to stator winding problems, mainly insulation deterioration. ...
