This paper analyzes and compares position estimation performances of fundamental-model-based sensorless control methods considering the effects of inverter nonlinearities and parameter estimation errors. Based on the investigation of four conventional sensorless control algorithms, estimated position error from each algorithm is represented in a quantitative manner. This representation is helpful in understanding how the error influences the position estimation performance. And, it is revealed that steady state position error can be expressed as a unified formula regardless of position estimation methods. The validity of the analysis is verified by computer simulations and experimental results.

A simplified analysis of influence of pole pairs on the steady-state behavior of induction motors is presented. The analysis makes simplifying assumptions to express relationship between key steady-state performance parameters of 2-pole reference motor compared to its multiple pole counterparts. The analysis is performed using considerations of fixed geometrical dimensions on one hand and fixed output power on the other hand. Available manufacturer catalogue data of medium voltage induction machines from one manufacturer is used to evaluate the soundness of the analysis. Also test and catalogue data analyses of commercially manufactured low voltage machines from different manufacturers are evaluated to determine extent to which they conform to the theoretical considerations of the analyses. The preliminary findings indicate more agreement with the medium voltage motors than the low voltage motors.

This paper proposes a methodology to model and control a three phase voltage source inverter (VSI) with LCL filter intended for distributed generation in microgrid scenario. Thus, the inverter should be able to operate in both grid-connected and islanded modes with a smooth transition between them. The strategy is to split the control input into two components. The first component is generated to make the voltages at capacitors to track sinusoidal references; meanwhile the second component is suitable to increase these voltages in order to achieve the certain amplitude and phase that guarantee the required output current. To obtain the controllers that generate these control signals, system is modeled in state-space and reduced to an equivalent single phase representation; state-feedback controllers are computed by means of Linear Matrix Inequalities solvers considering uncertainty on the grid inductance. Simulation results prove the validity of the proposed control system.

The performance of doubly-fed induction generators (DFIGs) would be affected by the rotor winding inter-turn short circuit fault, such as harmonics increase in electromagnetic quantities and torque pulsation. Thus, it is necessary to monitor and diagnose the rotor inter-turn fault for DFIGs. However, the rotor three-phase windings inherent imbalance and static air gap eccentricity may cause misdiagnosis of the rotor winding inter-turn fault. The finite element models of the DFIG are presented firstly, which consider the rotor three-phase windings inherent imbalance and static air gap eccentricity respectively. Then the rotor inter-turn short circuit faults of DFIGs are simulated under both conditions. Based on the characteristics analysis of the stator line voltage, rotor line current and electromagnetic torque from the simulation, a diagnosis method for the DFIG rotor inter-turn fault is proposed, which could avoid misdiagnosis caused by the rotor three-phase winding inherent imbalance and static air gap eccentricity and increase the diagnosis accuracy.

In this paper a computationally efficient high-fidelity multi-physics design tool applicable to E-core power inductors is developed. The tool is composed of 2-D electromagnetic and 3-D thermal finite analyses coupled to models for inductor core and winding loss. The models are fully parametrically defined and appear as a black-box problem which can be used to perform parameter studies or design optimisation. For example, the influence of strip or edge wound rectangular conductors on ac loss generation and thermal performance can be evaluated or inductor designs which satisfy a given specification can be identified. The tool is demonstrated by the design and experimental test of a high-energy-density filter inductor for an automotive application.

As the contribution of wind energy to the power grid increases, serious concern about its influence on the dynamic behavior of the power system has also increased. This has raised the need for advanced analysis and simulation tools that can study the complicated dynamic behavior of wind turbines, test their controllers as well as emulate a complex power grid. Therefore, to meet all the aforementioned goals, a reconfigurable hybrid wind farm testbed has been developed and implemented into a real-time simulation platform that has eight CPUs. The proposed wind farm testbed includes a Hardware-in-the-Loop (HIL) system involving a Doubly-fed Induction Machine (DFIM) test setup and wind turbine controllers. The wind farm model is also tested under normal and abnormal grid conditions. Several types of system symmetrical and asymmetrical faults are investigated. The first is a two-phase to ground fault at the point of common coupling (PCC) and the second is a three-phase to ground fault. An innovative approach referred to as Computer Twins is employed to react to these faults and maintain the stability of the power grid. A comprehensive set of test results are presented in this paper to demonstrate the capability of proposed testbed.

This paper investigates the calculation, modelling and interpretation of efficiency maps for electrical machines. The efficiency maps are calculated using a finite-element based mapping of losses, torque and flux-linkage as a function of the d- and q-axis currents and speed. For modelling efficiency maps, it is shown that a number of key loss types can be described in the form Tmωn. The effect of each of these losses on the shape of the efficiency map is then explored. It is found that practical efficiency maps can be approximated using a series of such terms which leads to a better understanding of the losses in the machine. The above results are validated using the loss and efficiency maps of three example machines.

Flyback switch mode power supplies have been widely used in low-power applications, such as DC/DC converters, solar micro-inverters and LED drivers. However, flyback converters have several problems related to the volume of the output capacitor as well as high output voltage noise; this is produced by the discontinuous output current. Consequently, interleaved operation with parallel connection on the secondary side can reduce the output current ripple compared with the single-phase flyback converter. Nevertheless, besides the output capacitor, the interleaved operation is unsuitable for transformers if it is desired to obtain light weight and compact performance. To address this problem, the interleaved flyback converter with integrated transformer has been proposed for achieving miniaturization of the output capacitor and transformers. There are mainly two types of the proposed flyback converter with integrated transformer: Parallel and Series types. These two types are categorized based on the connection on the primary side. Nevertheless, quantitative comparison of the volume and power loss has not been analyzed yet. Moreover, the design method of the integrated transformer also has not been conducted with clarity. Hence, in this paper, in order to provide a guide for the design of an interleaved flyback converter for achieving high power density, we analyze the quantitative volume and power losses of the integrated transformer and the input capacitor. Finally, this paper shows some experimental results that validate the appropriateness of the design method for the integrated transformer.

As the transformerless solar inverters have been pushed to an impressive 99% efficiency in residential and small commercial applications (less than 20 kW), high efficiency medium and large commercial scale (50-250 kW) transformerless solar inverters are gaining more and more attentions. However, due to the differences of inverter power ratings, grid voltages and standard requirements, there are new challenges and problems for the commercial scale photovoltaic system to eliminate the isolation transformers and achieve the competitive efficiency. This paper reviews and evaluates the state-of-art technologies of today's U.S. commercial scale PV inverters, and proposes the future trends for next generation commercial scale transformerless solar inverters. The transformerless inverter topologies, leakage current and existing standards are discussed and assessed. The goal of this paper is to address the new challenges of moving transformerless solar inverters into the commercial scale PV system with 99% efficiency.

This paper presents modeling and analysis of a hysteresis interior permanent magnet (IPM) motor drive for electric submersible pumps. A hysteresis IPM motor can self-start without the need of additional position sensors and complex control techniques. It does not have any slip power losses in the rotor at steady state which results in less heat dissipation and low electrical losses. When used in an electric submersible pump (ESP) for oil production, it has the ability to automatically adapt itself to the changes in well conditions. In this paper, a bond graph model of a hysteresis IPM motor ESP drive is used to predict the effect of rotor dynamics on the transient behavior of the submersible motor drive. Experimental investigations have been also carried out for a laboratory prototype 5HP hysteresis IPM motor drive. Due to increased efficiency and simplified controller requirements, the hysteresis IPM motor is proposed as a replacement for the standard induction motor currently used for downhole ESPs in offshore oil recovery plants.
