Multi-phase wind generation systems are emerging as a promising technology for distributed generation systems. These systems can present unbalanced voltages or phase faults for several reasons. In this paper a modular three-phase direct matrix converter topology is used as conversion stage in a six-phase generation system to supply the desired current to a load. To achieve a reliable performance in the conversion stage, an improved predictive current control is proposed that take advantage of the modularity of the converter to enhance the behavior and to provide the capability to work continuously even under unbalance in the source or during fault operation of the generation system whilst achieving the desired tracking and power quality. The technique is compared against a classical approach to show the benefits of the proposed.

The landscape of direct current (DC) solid-state circuit breakers (SSCBs) is growing and so too is the choice of primary components. There now exists a wide range of devices capable of withstanding voltage levels conducive to electrical transmission; though steady state efficiency of these devices remains a concern. Choosing primary components out of the growing selection pool can be cumbersome and prone to biased decision-making. The purpose of using a multifaceted mathematical approach to decision-making is to reduce these complications. The contribution of this paper will reduce biased decision-making when choosing primary components of SSCBs. This methodology consists of developing accurate and consistent simulation comparisons of steady-state efficiency, thermal performance, and cost of a variety of SSCB types, topologies, and solidstate device materials. The results contained within this paper demonstrate an achievable holistic approach to SSCB primary component choice.
直流(DC)固态断路器(sscb)的前景正在增长,主要部件的选择也是如此。现在有各种各样的设备能够承受有利于电力传输的电压水平;尽管这些器件的稳态效率仍然是一个问题。从不断增长的选择池中选择主要组件可能很麻烦,而且容易产生有偏见的决策。使用多方面的数学方法进行决策的目的是减少这些复杂性。本文的贡献将减少在选择sscb主要成分时的偏见决策。该方法包括对各种SSCB类型、拓扑结构和固态器件材料的稳态效率、热性能和成本进行准确和一致的模拟比较。本文中包含的结果展示了一种可实现的SSCB主要成分选择的整体方法。

The Student Journey Map (SJM) places learners at the center of sharing knowledge, with the support of a teacher who assumes the role of coach in the acquisition and dissemination of know-how. The SJM is designed to be experimented with in combination with the educational scripting approach of the Customer Journey Map. In our qualitative study, we formulated several propositions, the primary one being that it is important to offer face-to-face social exchanges in student-based environments. The SJM helps to compensate for isolation by recreating a social link between students. The teacher begins by establishing the pedagogical scenario of the course with its objectives, the topics to be covered, and practical training sessions. Our experiments show that by using the SJM approach, students collaborate directly with each other, thereby allowing co-learning that does not occur in a merely transposed online teaching approach.
学生旅程地图(SJM)将学习者置于分享知识的中心,在教师的支持下,教师在获取和传播知识方面扮演教练的角色。设计SJM是为了与客户旅程地图的教育脚本方法相结合进行实验。在我们的定性研究中,我们提出了几个命题,主要的一个是在以学生为基础的环境中提供面对面的社会交流是很重要的。SJM通过重建学生之间的社会联系来弥补孤立。教师首先建立课程的教学场景,包括目标、要涵盖的主题和实践培训课程。我们的实验表明,通过使用SJM方法,学生们直接相互合作,从而允许共同学习,而这在仅仅转换的在线教学方法中不会发生。

In Permanent Magnet Synchronous Motors (PMSMs) with multistrands windings, inter-turn short circuit (ITSC) faults occur in two types. One is that the ITSC fault occurs between two spots of a single strand and the other is that the ITSC fault occurs between two different strands. We proposed a fault indicator to detect two types of inter-turn short circuit faults in PMSMs that have multistrands windings. The fault indicator is calculated from stationary dq currents and their Hilbert transforms. The fault indicator converges to zero in healthy state but increases proportionally to the severity of the fault in faulty state. We validated the fault indicator with finite element method (FEM) simulation data. The proposed fault indicator only uses current data, so the indicator is simple and efficient tool to detect ITSC faults in PMSMs with multistrands windings.
在多股绕组的永磁同步电动机(pmms)中,匝间短路(ITSC)故障有两种类型。一种是ITSC故障发生在单链的两个点之间,另一种是ITSC故障发生在两条不同的链之间。提出了一种故障指示器,用于检测多股绕组的永磁同步电动机的两种匝间短路故障。故障指示器由稳态dq电流及其希尔伯特变换计算得到。故障指示灯在健康状态下收敛为零,在故障状态下随着故障的严重程度成比例增大。用有限元仿真数据对故障指示器进行了验证。所提出的故障指示器仅使用当前数据,因此该指示器是检测多股绕组pmsm ITSC故障的简单有效的工具。

A hierarchical fault detection and fault location framework consisting of two levels is proposed for DC ring bus microgrids. In the primary level, a decentralized fault detection scheme based on back propagation (BP) artificial neural network (ANN) and discrete wavelet transform (DWT) is proposed to classify the pole-to-pole (P-P) and pole-to-ground (P-G) faults under measuring noises and load disturbances only relying on the information needed by the local double closed-loop controller, and the diagnosis speed and reliability of system are guaranteed. In the secondary level, a distributed line fault location method is presented by synthesizing the detection results of local and neighbor DG units with low bandwidth communication, and the accuracy of line faults is improved greatly without the central controller and additional sensors. Several simulation cases are analyzed under various fault configurations such as load mutations, different fault types, fault locations and fault impedance. The effectiveness and feasibility of the proposed method are verified.
针对直流环形母线微电网,提出了一种由两级组成的分层故障检测与定位框架。在初级阶段,提出了一种基于反向传播(BP)人工神经网络(ANN)和离散小波变换(DWT)的分散故障检测方案,仅依靠局部双闭环控制器所需的信息对测量噪声和负载扰动下的极对极(P-P)和极对地(P-G)故障进行分类,保证了系统的诊断速度和可靠性。在二级线路故障定位中,通过综合低带宽通信的本地和邻近DG单元的检测结果,提出了一种分布式线路故障定位方法,在不使用中央控制器和附加传感器的情况下,大大提高了线路故障定位的精度。分析了负载突变、不同故障类型、故障位置和故障阻抗等不同故障配置下的仿真案例。验证了该方法的有效性和可行性。

The use of materials with controlled electromagnetic properties, such as Curie temperature, for the development of different domestic induction heating applications can improve their safety, energy efficiency and performance.In this article, a measurement system for the magnetic characterization of ferromagnetic materials is presented. The study focuses on materials with low Curie temperature, since typically the information provided by the manufacturers of this type of alloys is limited, giving only the Curie point. It has been obtained the value of its magnetic permeability for different conditions of temperature, excitation current and frequency. These data are useful to carry out simulations of different induction heating applications and design power converters for these systems.The results obtained confirm the manufacturer’s Curie point and also provide the magnetic permeability values and their dependencies for use in simulations or system design.

Galvanic isolation, characterized by the inclusion of a transformer as a conversion stage, is the most commonly used method to eliminate hazardous common-mode (CM) current in grid tied converters. However, this solution tends to harm system efficiency and power density, while increasing costs. This issue is of particular importance for electric vehicle, where the industry is devoting significant resources to improve vehicle power density, cost, and range. This paper proposes a general, systematic method to design nonisolated converters with near zero CM currents. Several options of connection structure are provided, and two converters are designed to elucidate the method. Simulations are performed to demonstrate the CM performance improvement delivered by the proposed solution.

Designing and testing of electric vehicles (EVs) is a time-consuming process because of the iterations involved in the electric machines (EMs) and their power electronics (PEs) designs. Most of the time, both designs are done sequentially by using the output of the machine design step for proper sizing of its PEs. This paper proposes a novel fast and systematic method that sets a common ground for electric machine design and drive engineers allowing them to work in parallel and speed up the EV drivetrain development process. The proposed method is based on estimating key parameters such as magnet flux linkage, the d-q axis inductances, motor terminal voltages, and currents based on the drive requirement in terms of torque-speed envelope and battery terminal voltage. A case study based on an industrial project has been performed to show the feasibility of the proposed approach on a 7.12 kW surface and inset permanent magnet synchronous machine (SPMSM and IPMSM) drivetrains. New equations have been developed for getting IPMSM parameters from a feasible SPMSM design. Design steps and performance characteristics using simulation and finite element analysis (FEA) software are discussed. The effectiveness of the proposed design approach is also validated using MATLAB Simulink.

This paper focuses on the interoperability of smart devices (sensor and actuators) in the context of the Industrial Internet of Things. IEC 61499 and IEEE 1451 standards are employed to implement a distributed control and measurement system. It addresses how two standards can interoperate and communicate efficiently by complementing each other. Both standards share common properties which are the essential elements of any IoT system. The Message Queue Telemetry Protocols (MQTT) is utilized to provide an interoperable network interface between the IEEE 1451 family of standards and the IEC 61499 standard. An interoperability test platform is provided to show how both standards communicate efficiently for a simple read/ write automation process.
本文主要研究工业物联网背景下智能设备(传感器和执行器)的互操作性。采用IEC 61499和IEEE 1451标准来实现分布式控制和测量系统。它解决了两个标准如何通过相互补充来进行互操作和有效通信。这两个标准都具有共同的属性,这些属性是任何物联网系统的基本要素。消息队列遥测协议(MQTT)用于在IEEE 1451系列标准和IEC 61499标准之间提供可互操作的网络接口。提供了一个互操作性测试平台,以显示两个标准如何为简单的读/写自动化过程有效地进行通信。
