Study on Application of Two Different Magnetic Materials in Rotor of Cylindrical Synchronous Generator to Produce Reluctance Torque
Synchronous generators are of two type’s salient pole type and round rotor type. The load angle curve of a cylindrical rotor synchronous machine comprises a single sine term only while in salient pole synchronous generators, power-angle characteristic has two terms. The first term is the fundamental component due to field excitation (the same as the cylindrical rotor) and the second term ...
متن کاملModeling of Grid-connected Superconducting Synchronous Machines
We developed an accurate, efficient and flexible modeling method for the steady-state and transient analysis of grid-connected superconducting synchronous machines. On the one hand, the machine flux linkages and electromagnetic torque as function of operational parameters are obtained from static finite element analysis and stored in lookup tables. On the other hand, the machine is represented ...
متن کاملModeling of synchronous machines with magnetic saturation
This paper deals with a method to derive multiple models of saturated round rotor synchronous machines, based on different selections of statespace variables. By considering the machine currents and fluxes as space vectors, possible d–q models are discussed and adequately numbered. As a result several novel models are found and presented. It is shown that the total number of d–q models for a sy...
متن کاملMaximum Efficiency per Torque Control of Permanent-Magnet Synchronous Machines
Abstract: High-efficiency permanent-magnet synchronous machine (PMSM) drive systems need not only optimally designed motors but also efficiency-oriented control strategies. However, the existing control strategies only focus on partial loss optimization. This paper proposes a novel analytic loss model of PMSM in either sine-wave pulse-width modulation (SPWM) or space vector pulse width modulati...
متن کاملPMU-Based Matching Pursuit Method for Black-Box Modeling of Synchronous Generator
This paper presents the application of the matching pursuit method to model synchronous generator. This method is useful for online analysis. In the proposed method, the field voltage is considered as input signal, while the terminal voltage and active power of the generator are output signals. Usually, the difference equation with a second degree polynomial structure is used to estimate the co...
