“…The mechanical losses, which are also known as rotational losses, are frequently lumped with core losses and depend on the rotating speed and flux linkage [5]. The core and friction losses together are assumed to be 1% of the generator rated power [32]. The stray losses are assumed to be 1% of the generator electrical power [33].…”

Wind-Speed Estimation and Sensorless Control for SPMSG-Based WECS Using LMI-Based SMC

et al. 2020

To enhance system reliability and to reduce the cost and complexity, this paper presents an efficient wind-speed estimation method and a sensorless rotor-position/speed control method for a surface-mounted permanent-magnet synchronous generator (SPMSG)-based variable-speed direct-drive wind-energy conversion system (WECS). In this regard, sliding mode control (SMC) based on a linear matrix inequality (LMI) is proposed to estimate the rotor position of an SPMSG. This method depends on measured electrical quantities, such as stator voltages and estimated stator current error, to evaluate the back electromotive force components, which are used to estimate the rotor position. The rotor speed is assessed according to the rate of change of the estimated rotor position. The wind speed is estimated by estimating the backpropagation power flow according to the nonlinear dynamical power wind-speed characteristics of the wind turbine. In estimating the rotor position, the proposed LMI-based SMC design provides good steadystate and dynamic performances under all operating modes of the WECS. The proposed control schemes are validated by simulating a test system, i.e., a 250-kW SPMSG-based WECS, in MATLAB/Simulink. The results confirm the effectiveness and correctness of the designed control schemes in estimating and tracking the actual rotor position/speed and wind speed with trivial errors.INDEX TERMS Back electromotive force (BEMF), linear matrix inequality (LMI), sensorless control, sliding mode control (SMC), surface-mounted permanent-magnet synchronous generator (SPMSG), windenergy conversion system (WECS).

“…Permanent Magnet Synchronous Motors (PMSMs) and Generators (PMSGs) have high efficiency, high power density, rigid structure, and mature control systems making them a valuable choice for modern industrial applications and renewable energy applications [1], [2]. Wind turbines, wave energy, tidal energy, and marine shaft generator system applications depend heavily on PMSG [3]- [5]. Also, PMSMs have been used in different applications such as propulsion systems [6], electric vehicles [7], and starter generators [8].…”

This paper investigates the detection of inter-turn phase faults in Permanent Magnet Synchronous Generators (PMSGs) using the Unscented Kalman Filter (UKF) compared to the Extended Kalman Filter (EKF). PMSGs are subject to several faults such as bearing, eccentricity, demagnetization, short circuit, and inter-turn faults. Accurate and early detection of the fault type is crucial for robust operation. Several techniques can detect these faults. UKF and EKF are presented here as one of the model-based fault diagnosis techniques. In the presented simulation, a comparison between the UKF and EKF estimation response of the fault has been shown. Both techniques have provided the ability to detect the inter-turn fault with the proposed PMSG fault model. However, the difference between the estimation response accuracy and speed plays an important role to decide the most effective technique.

“…Nevertheless, most of these papers are focused on analysis, presenting the results and the advantages of a designed machine. The remaining few concerning the design process [13][14][15] do not address wound-rotor salient-pole synchronous generators. Moreover, it is extremely rare to find a paper presenting a complete design procedure.…”

A Step-by-Step Procedure to Perform Preliminary Designs of Salient-Pole Synchronous Generators

This paper presents a straightforward step-by-step procedure to design salient-pole synchronous generators, starting with its main specifications and finishing with all necessary data to put it on production. As most of the electricity is generated by synchronous generators, the design of these machines remains an interesting subject, but, although it is important, it is difficult to find a complete step-by-step procedure in the literature. The proposed procedure can be followed by an electrical engineer or student and, distinctively from most papers and books, all steps are presented. Such a procedure is based on analytic calculations, eventually relying on finite element simulation to verify if everything is all right and to adjust some design parameters. All calculations have been chosen to keep the design as simple as possible; otherwise, it would not be possible to present all steps and procedures. Therefore, it can be used for beginners in the art of design-synchronous generators, applied to obtain an initial design, or be adopted by any electrical engineering course, not only aiming to be an introductory electrical machine design course but mainly to enhance the students’ comprehension of synchronous machines. The results have been compared with finite element simulation, presenting very small differences.
