Power system dynamic problem is the study which dealing with synchronism among interconnected machines. In any scenario all interconnected synchronous machines should remain in synchronism if the system is stable; i.e., they should all remain operating in parallel and at the same speed.

This may result in oscillatory, but if the system is stable, these oscillations will be damped towards to stable operating condition.

Torque estimation in permanent magnet synchronous machines and synchronous reluctance machines is required in many applications. Torque produced by a permanent magnet synchronous machine depends on the permanent magnets’ flux and d q -axes inductances, whereas torque in synchronous reluctance machines depends on the d q -axes inductances. Consequently, precise knowledge of these parameters is required for proper torque estimation. The use of high frequency signal both for permanent magnets’ flux and d q -axes inductances estimation has been recently shown to be a viable option. This paper revi

Abstract:

In the area of high power drives, double star synchronous machines are an interesting choice compared to conventional synchronous machines, due to the relatively low torque ripple created. In this paper, direct torque control (DTC) of double star permanent magnet synchronous machine (DS-PMSM) using artificial neural networks (ANN) is proposed. MATLAB/Simulink results show the comparison between direct torque control (DTC) and direct torque control using artificial neural networks (ANN). The analysis of the results shows good performance for speed, small torque and flow ripple when using the ar

Abstract:

Abstract Floating offshore wind turbines are ideal for deeper waters, providing access to stronger and more stable winds. The Counter-Rotating Axis Floating Tilting (CRAFT) turbine features a unique design with two counter-rotating turbines on a tilted vertical shaft and two independent electrical machines submerged below sea level. The primary generator, connected to both turbines, includes counter-rotation which doubles the relative torque, while the secondary machine controls the upper turbine. This study examines the impact of primary and secondary machine efficiency on electricity generat

Abstract:

This work describes a method which illustrates the benefits of the visual aspects of MATLAB/SIMULINK for educational purposes. The method is specially developed for transient analysis of synchronous machines given by a simplified model. Details such as the exciter circuit, turbine and governor systems of a synchronous machine which is linked to an infinitive bus through two equivalent lines are given and this system is implemented in SIMULINK. The considered synchronous machine has a rated power capacity of 160 MVA and rated voltage of 15 kV.

Abstract:

Abstract Commonly, the Park model is used to calculate transients or steady-state operations of synchronous machines. The expanded Park theory derives the Park equations from the phase-domain model of the synchronous machine by the use of transformations. Thereby, several hypothesis are made, which are under investigation in this article in respect to the main inductances of two different types of synchronous machines. It is shown, that the derivation of the Park equations from the phase-domain model does not lead to constant inductances, as it is usually assumed for these equations. Neverthel

Modeling and simulation of pulp mill plant permanent magnet synchronous machines (PMSM) with damper windings using Matlab/Simulink is presented. Pulp mill is a manufacturing facility that converts wood chips, timber, wood products into wood pulp that is used to produce paper, cardboard, thick fiber board, which can be used by a paper mill for further processing. Pulp and paper industry has been considered a large consumer of energy and constitute a native treat to the plant as a result of machines transient due to heavy load variation.

Abstract:

Electrical machines are important parts of different power systems. The application of high temperature superconductors (HTS) in electrical machines is very promising due to high transport currents. This paper reviews various topologies of superconducting motors and generators using HTS published in the literature in recent time. It begins with a brief presentation of the HTS material used in electrical machines. The description of AC losses and cryogenic systems is done afterwards. Then we offer a striking description of the various realizations of HTS electrical machines such as half HTS syn

Abstract:

Virtual inertia control is a methodology to make inverter-based resources (IBR) behave like a synchronous machine. However, an IBR cannot fully emulate the response of synchronous machine because of its low-current capacity. When the inertial response of an IBR is affected by the current limitation, the synchronization of the synchronous machine simulated virtually inside the IBR controller with the other synchronous generators in the grid is affected, which may cause step-out of the simulated generator. We propose a methodology which can keep the synchronization by modifying internal induced

AbstractThis paper evaluates the applicability of a newly proposed method for the indirect efficiency determination of permanent magnet synchronous machines by measuring individual losses. Similar methods are well-known and standardized for other kinds of electrical machines, but for permanent magnet synchronous machines, only the direct measurement of input and output power is standardized for efficiency determination according to IEC 60034-2‑1. Measurements and finite element simulations are carried out for four selected test machines with a rated power range between 45 kW and 90 kW and with

Abstract:

The demand for electric machines has been rising steadily for several years—mainly due to the move away from the combustion engine. Synchronous motors with rare earth permanent magnets are widely used due to their high power densities. These magnets are cost-intensive, cost-sensitive and often environmentally harmful. In addition to dispensing with permanent magnets, electrically excited synchronous machines offer the advantage of an adjustable excitation and, thus, a higher efficiency in the partial load range in field weakening operation. Field weakening operation is relevant for the applica
