DC networks have generated much interest in recent years, from transmission in high voltage to their use in distribution systems. One of the major challenges is to replace the high efficient and reliable ac transformer, especially at high voltage and step ratio. New resonant modular multilevel topologies have arisen as an alternative, mainly because of advantages such as optional use of transformers, natural voltage balance, simple control and soft-switching. However, this type of operation generates a high peak current, does not allow control of power flow in all power range and has a limited range of voltage variation. This paper proposes an asymmetrical triangular current mode applied in high step ratio Modular Multilevel dc-dc Converters that achieves bidirectional control of the power, soft-switching and a natural balance of the voltage in the capacitors. The simulation results show the bidirectional operation and the capacitor voltage balance of the converter under different operating conditions with high efficiency and low peak current compared to resonant mode. The proposal was tested in a down-scale prototype, confirming the operation principle.
近年来,直流网络引起了人们的极大兴趣,从高压传输到配电系统。如何替代高效可靠的交流变压器,特别是在高电压和高阶跃比下的交流变压器,是当前的主要挑战之一。新的谐振模块化多层拓扑作为一种替代方案已经出现,主要是因为它具有可选使用变压器、自然电压平衡、简单控制和软开关等优点。然而,这种类型的操作会产生很高的峰值电流,不允许在所有功率范围内控制潮流,并且电压变化范围有限。提出了一种应用于高阶跃比模块化多电平dc-dc变换器的非对称三角形电流模式,实现了功率的双向控制、软开关和电容内电压的自然平衡。仿真结果表明,与谐振模式相比,该变换器在不同工作条件下具有高效率和低峰值电流的双向工作和电容电压平衡特性。该方案在一个小尺寸原型机中进行了测试,证实了其工作原理。

Switching speed of the next-generation power devices based on the wide-bandgap semiconductors such as silicon carbide and gallium nitride are more than ten times faster than the conventional silicon insulated-gate bipolar transistors. This may increase frequency ranges of electromagnetic noise accompanied by switching operations of power converters. Besides, the operating frequency ranges of noise filters are limited due to frequency dependencies of magnetic materials and parasitic components of passive components, thus, the realization of the high-frequency (HF) noise filter with the operating frequency range beyond several ten megahertz is difficult. This paper presents a modeling technique for estimating the operating frequency range of the HF three-phase common-mode (CM) inductors. The proposed method includes a novel simple estimation technique of winding stray capacitance. The CM impedance measurement results validate that the proposing model can estimate the operating frequency range of the HF three-phase CM inductor while securing practically sufficient precision at the design-stage.
基于碳化硅和氮化镓等宽带隙半导体的下一代功率器件的开关速度比传统的硅绝缘栅双极晶体管快十倍以上。这可能会增加电源变换器开关操作时电磁噪声的频率范围。此外,由于磁性材料的频率依赖性和无源元件的寄生成分,噪声滤波器的工作频率范围受到限制,因此工作频率范围超过几十兆赫兹的高频(HF)噪声滤波器很难实现。本文提出了一种估算高频三相共模电感工作频率范围的建模技术。该方法包括一种新颖的简单的绕组杂散电容估计技术。CM阻抗测量结果验证了所提出的模型可以估计高频三相CM电感的工作频率范围,同时在设计阶段保证了足够的精度。

Different kinds of faults in the motor can occur, which causes various and independent variations in the magnetic flux distribution of machine and consequently causes different changes in the behavior of the motor and its performance. These changes reflect in the machine flux linkage, which can be determined by the machine voltage. A novel fault detection and identification technique for inter-turn-short fault and irreversible demagnetization fault in interior permanent magnet synchronous motor are presented in this paper. The deviation caused by the inter-turn short fault and irreversible demagnetization fault in the angle between $d$-axis voltage and $q$-axis voltage, which is termed as voltage or load angle is analyzed. It is observed that in case of demagnetization fault the voltage angle increases, whereas in case of inter-turns short fault it decreases. In this study, we used this unique phenomenon for the detection and identification of these faults. The proposed method is verified by simulation and experiments.

Improved Over Modulation Strategy in DTC with Constant Frequency Torque Controller of PMSM for Quick Torque Control at Different Dynamic Conditions 改进的永磁同步电机恒频转矩控制器直接转矩控制过调制策略,实现不同动态条件下的快速转矩控制
Pub Date : 2018-09-01 DOI: 10.1109/ECCE.2018.8557694

This paper proposes an improved dynamic overmodulation for direct torque control with constant switching frequency controller (DTC-CFTC) of AC motor drives to achieve fast dynamic performance under different operating conditions. The dynamic process of the DTC is obtained by the selection of active voltage vectors in the torque trainset. To further improve the dynamic performance, the most optimized active voltage is identified and selected based on the flux position. However, owing to the nature of the DTC-CFTC, some zero voltage vectors are selected in the dynamic process. As such, with the optimized voltage vector, the torque performance of DTC-CFTC is still slow. By simultaneous modification of torque and flux error statuses, the proposed overmodulation strategy can overcome this problem and achieve very fast torque response at different speed and torque operations. The effectiveness of the proposed overmodulation in DTC-CFTC of PMSM is verified by simulation results.
本文提出了一种改进的交流电机驱动恒开关频率控制器(DTC-CFTC)直接转矩动态过调制方法,以实现交流电机驱动在不同工况下的快速动态性能。通过选取转矩列中的有源电压矢量,得到了自动转矩控制系统的动态过程。为了进一步提高动态性能,根据磁通位置识别并选择最优的有功电压。然而,由于DTC-CFTC的特性,在动态过程中会选择一些零电压矢量。因此,在优化后的电压矢量下,DTC-CFTC转矩性能仍然较慢。通过同时改变转矩和磁链误差状态,该过调制策略可以克服这一问题,在不同转速和转矩操作下实现非常快的转矩响应。仿真结果验证了该过调制方法在永磁同步电机DTC-CFTC中的有效性。

The feed-forward decoupling PQ control strategy is widely used in the grid-connected control for the micro-grid inverter. When the grid voltage is unbalanced, the output of the inverter usually contains the negative sequence components, the third harmonic and other components which will affect active and reactive power stabilization with PQ control. A novel PQ control strategy with non phase-locked loop (PLL) is proposed in this paper. By presetting a synchronous rotation frequency, the negative errors for the specified frequency can be converted each other. With Hilbert transform of the amplitude and phase, the positive sequence harmonic components, the fundamental negative sequence component and the negative sequence harmonic components can be eliminated. Even under the abominable grid conditions, it can extract the synchronization signal and improve the performance of the PQ control. Simulation results verify the effectiveness and feasibility of the proposed strategy.

This paper presents an instantaneous pulse power compensator (IPPC) concept to achieve ultra-high density with zero voltage ripple and zero dc-link capacitor for high-power-density single-phase inverter application. Compared with traditional 2ndorder method with various power decoupling topologies, IPPC proposed a totally new theoretical analysis from a pulse-power point of view. For dc-link voltage ripple evaluation, traditional theoretical analysis is not suitable for small-capacitance power decoupling applications, however, pulse power analysis can be applied in the whole range. From a view of state-of-the-art on power decoupling methods, a comparison figure with voltage ripple and dc-link capacitance is given to show the limitation of traditional power decoupling method and improvement of IPPC method on minimizing dc-link capacitance. One case study is presented with full-bridge topology with simulation results. Furthermore, one Silicon Carbide (SiC) based inverter and the IPPC based circuit are built. Experimental results verify the proposed idea very well.

We present the results of a case-study analysis for optimal sizing of a battery energy storage system (BESS), photovoltaic and/or genset (or cogeneration unit) using a recently developed microgrid design tool (MGDT) which integrates advanced energy management algorithm, including MPC (Model Predictive Control) approach embedded into the optimization engine. MPC algorithm is based on the resolution of an optimization problem that uses the variable electric tariff rates (for both energy and demand), the predicted load, and distributed energy resources production profiles to minimize the cost function over a time horizon (typically 24-hours) with respect to optimal energy profile results. This Matlab Simulink based tool was able to produce comparative results to indicate battery-autonomy and how the battery design impacts the cost when the microgrid operates in grid connected mode. The analyzed KPIs were: renewable penetration ratio, yearly cost for utility grid, cash flow on the full project lifetime.

Modular Multilevel Converter (MMC) with integrated Battery Energy Storage System (BESS), where the battery strings are connected to each Submodule (SM) through DC-DC converters, can transfer energy among the DC link, the AC grid, and the batteries. And this flexible structure is suitable to be applied in the microgrid and the wind power generation system, in which the BESS is needed to smooth energy fluctuations. However, compared with the common MMC, the Battery Manage System (BMS) which is used in BESS to balance the State of Charge (SOC) among batteries makes the capacitor voltage ripple of each Submodule different and complicated. The capacitor selection needs to take this into consideration. Some simulation results under different initial SOC situations derived from a Simulation model are given to evaluate the influence. And some corresponding conclusions and suggestions are obtained based on these simulation results.

This paper performs electromagnetic (EM) and thermal coupled simulation based on 2D transient electromagnetic and 3D thermal model of a triple redundant 9-phase permanent magnet-assisted synchronous reluctance motor (PMASynRM) under various fault conditions at different speeds. The coupled simulation process is controlled by python scripts. The resultant temperatures under EM-thermal coupled simulation will be comprehensively compared with those under thermal-only simulation. The predicted temperatures by the 3D thermal model will be compared with the test results for validation. The outcomes of the study not only gives a better understanding of the thermal behavior, but also provides a guidance to the necessity of the EM-thermal coupled simulation under different fault conditions as well as to determination of the maximum permissible fault detection time before permanent damage due to the fault may occur.
本文基于三冗余9相永磁辅助同步磁阻电机(PMASynRM)的二维瞬变电磁和三维热模型,对其在不同转速下的各种故障条件进行了电磁和热耦合仿真。耦合仿真过程由python脚本控制。将电磁-热耦合模拟的结果温度与仅热模拟的结果温度进行全面比较。将三维热模型预测的温度与试验结果进行对比验证。研究结果不仅可以更好地理解热行为,还可以指导在不同故障条件下进行电磁-热耦合模拟的必要性,以及确定故障可能导致永久损坏之前的最大允许故障检测时间。

With the number of vehicles traveling every year increasing, it is becoming more important to make every trip as efficient as possible. This leads to the question, is it possible to recover a fraction of the energy that vehicles use? This paper explores the winds produced by road vehicles traveling at high speeds and, by extension, the winds produced by high speed rail and the design of a device that successfully captures and converts this wind into usable electricity. ANSYS Fluent and Solidworks Flow Simulation were used to obtain the induced wind profiles of the vehicles. A novel small scale Savonius wind turbine was then designed and constructed around reasonable perimeters for this application and tested for efficiency. The results of the simulations and experimental testing are provided to prove the proposed wind energy harvesting concept has potential for commercial use.
随着每年出行车辆数量的增加,使每一次出行尽可能高效变得越来越重要。这就引出了一个问题,是否有可能回收车辆使用的一小部分能源?本文探讨了公路车辆高速行驶产生的风,以及高速铁路产生的风,并设计了一种设备,成功地捕获并将这种风转化为可用的电力。利用ANSYS Fluent和Solidworks Flow Simulation软件对车辆的诱导风廓线进行了仿真。然后设计并建造了一种新型的小型Savonius风力涡轮机,并对其进行了效率测试。模拟和实验测试的结果证明了所提出的风能收集概念具有商业应用的潜力。
