A novel topology for choosing best method to detect the type of fault occurred at any periphery of a radial power network through machine learning has been presented. Firstly, conventional load flow analysis has been performed, and then, different types of sequence parameters have been found for healthy and different fault conditions at peripheral load buses. Then, sequence component-based fault diagnosis has been performed at the end, and six types of machine learning-based methods have been applied for the discrimination of all types of faults. From a comparative study, the best suitable method has been derived.

With the advancements of different renewable energy sources, DC microgrid gets a scope to explore its operation. The protection of low voltage DC (LVDC) microgrid faces a greater challenge with comparison to AC microgrid because of the absence of zero crossing nature of DC signal. As solid state circuit breaker (SSCB) is more capable of providing fast operation compared to mechanical or hybrid type of circuit breaker, it gets more attention by the researchers. Previously used thyristor based circuit breaker takes operation time about tens to few hundred micro seconds. In this research, a new topology of thyristor based SSCB has been proposed for DC microgrid, that breaks the faulty line with lower time compared to existing topologies. Along with this, it also requires lesser numbers of thyristor switches, which reduce the overall losses of circuit breaker. The protection of a monopolar DC line against permanent pole-to-pole fault has been successfully studied in this paper through MATLAB/Simulink platform.
随着各种可再生能源的发展,直流微电网的运行有了一定的探索空间。由于直流信号不具有过零特性,对低压直流微电网的保护面临着比交流微电网更大的挑战。由于固态断路器相对于机械式或混合式断路器具有快速运行的特点,越来越受到研究人员的关注。以前使用的晶闸管断路器的操作时间约为几十到几百微秒。在本研究中,提出了一种基于晶闸管的新型直流微电网SSCB拓扑,与现有拓扑相比,该拓扑可以在更短的时间内断开故障线路。与此同时,它还需要较少数量的晶闸管开关,这减少了断路器的总体损耗。本文通过MATLAB/Simulink平台成功地研究了单极直流线路对永久极对极故障的保护问题。

This paper analyzed the effect of various maximum power point tracking (MPPT) algorithms applied on the solar PV module and describes the importance of Model Predictive Control (MPC) algorithm applied for MPPT of solar PV. Perturb & Observe (P&O) and Incremental Conductance (InC) based tracking algorithms are the conventional and most popular tracking algorithms for MPPT of solar PV module, but they are lacking due to low efficiency with slower tracking speed of maximum power point (MPP) and higher oscillations. DC-DC boost converter has been used to scale the low-level voltage into high-level voltage. The complete setup inclusive of PV module, DC-DC boost converter and tracking algorithms has been designed and analysed on MATLAB/Simulink Software and the simulated results shows the performance of the applied algorithms on the PV module setup and suffice that MPC based tracking algorithm is well suited for solar PV MPPT setup.

The single-ended primary-inductor converter(SEPIC) is a DC-to-DC converter that allows both the operations of voltage level steps up and steps down. The SEPIC converter output is controlled by the switch duty cycle. The SEPIC converter consists of two inductors and two capacitors; hence it is a fourth-order converter. The state space model is obtained by using the state space averaging technique. Further, its order is reduced to first, second and third order using a modified Routh table and stability equation-based diminution techniques. Impulse response, step response, and Bode response of both the interval limits are plotted. The results show the usability and effectiveness of the proposed converter.

Reduced CMV SVPWM Scheme for Three-Level Z-Source NPC Inverter for PV Grid Integration 面向光伏并网的三电平z源NPC逆变器简化CMV SVPWM方案
Pub Date : 2023-01-03 DOI: 10.1109/ICPEE54198.2023.10060515

Renewable energy and various drive applications favor multilevel inverters with voltage boosting capabilities. For those applications, the common mode voltage (CMV) produced by multilevel inverters must be limited. Consequently, a simplified space vector pulse width modulation (SVPWM) scheme for the three-level Z-source neutral point clamping (NPC) inverter with special switching sequences is proposed to achieve voltage boosting and common mode voltage reduction. Three-level SVPWM is implemented using the two-level SVPWMM method to reduce the computational load of dwell time calculations. Restricting CMV to 1/6th of the dc-link voltage requires eliminating small vectors with a higher CMV. The voltage is boosted by inserting shootthrough states into the switching sequences. Harmonics content in the line voltage remains unchanged despite voltage boosting and CMV reduction. The theoretical analysis results are verified in the simulation studies that are conducted in MATLAB/Simulink software.
可再生能源和各种驱动应用青睐具有升压能力的多电平逆变器。对于这些应用,必须限制多电平逆变器产生的共模电压(CMV)。因此,提出了一种简化的空间矢量脉宽调制(SVPWM)方案,用于具有特殊开关顺序的三电平z源中性点箝位(NPC)逆变器,以实现升压和共模降压。为了减少停留时间计算的计算负荷,采用两级SVPWMM方法实现了三级SVPWM。将CMV限制在直流电压的1/6需要消除具有较高CMV的小矢量。通过在开关序列中插入穿透状态来提高电压。尽管电压升高,CMV降低,但线路电压中的谐波含量保持不变。在MATLAB/Simulink软件中进行了仿真研究,验证了理论分析结果。

In a closed loop control, operating point oscillations occur, the PI controller's performance is unsatisfactory as a result of tuning issues. In this paper, the concept of indirect vector control for an asynchronous motor drive is introduced using a type 2 neuro-fuzzy control method (T2NFC). A comparative performance with PI, type-l TINFC and T2NFC is done under various operating conditions of the asynchronous motor drive. It is investigated how well the induction motor performs in terms of its current, torque, flux variation, and speed. The simulated performance shows that T2NFC based Indirect vector-controlled drive gives better performance, less torque ripple and lesser spikes in the current as compared to TINFC and PI based control.

This paper investigates the performance of multiphase interleaved boost converter topologies for fuel cell electric vehicle (FCEV) system. Fuel cells (FC) have a low voltage and high current characteristics. The output voltage of a fuel cell stack must be increased to approximately 400V$sim$700V to be suitable for the motor drive system. Therefore, a DC/DC step-up converter is crucial for interfacing fuel cell stack with the DC bus of the vehicle.Owing to the volumetric constraints and other performance requirements, the FC connected DC/DC converter is expected to possess high power density, low weight, high efficiency and good thermal performance. Further, it is of paramount importance to maintain the output current ripple of FC for its enhanced life span. Interleaved boost converter (IBC) topologies are found to satisfy all these requirements of FCEV application. Hence in this paper, a performance comparison of few interleaved topologies appropriate for FCEV drive train is presented. It is observed that six phase IBC is superior to other two variants namely two phase and four phase IBC. The output voltage, input current and losses are analysed for all the three topologies. The design of the closed loop control algorithm is discussed lucidly. The results of extensive simulations carried out in MATLAB environment are presented.
本文研究了用于燃料电池电动汽车系统的多相交错升压变换器拓扑结构的性能。燃料电池(FC)具有低电压、大电流的特点。燃料电池堆的输出电压必须增加到大约400V / 700V才能适用于电机驱动系统。因此,DC/DC升压转换器对于燃料电池堆与车辆直流母线的接口至关重要。由于体积限制和其他性能要求,期望FC连接的DC/DC变换器具有高功率密度、低重量、高效率和良好的热性能。此外,维持FC的输出纹波对其延长寿命至关重要。交错升压变换器(IBC)拓扑结构可以满足FCEV应用的所有这些要求。因此,本文对几种适合燃料电池汽车传动系统的交错拓扑结构进行了性能比较。观察到六相IBC优于其他两种变体,即两相和四相IBC。分析了三种拓扑结构的输出电压、输入电流和损耗。对闭环控制算法的设计进行了详细的讨论。给出了在MATLAB环境下进行的大量仿真结果。

Further, it is of paramount importance to maintain the output current ripple of FC for its enhanced life span. Interleaved boost converter (IBC) topologies are found to satisfy all these requirements of FCEV application. Hence in this paper, a performance comparison of few interleaved topologies appropriate for FCEV drive train is presented. It is observed that six phase IBC is superior to other two variants namely two phase and four phase IBC. The output voltage, input current and losses are analysed for all the three topologies. The design of the closed loop control algorithm is discussed lucidly. The results of extensive simulations carried out in MATLAB environment are presented.","PeriodicalId":250652,"journal":{"name":"2023 International Conference on Power Electronics and Energy (ICPEE)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128811326","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The motors used in an electric vehicle such as induction motors are inferior to their dynamic characteristics. Similarly, the utilization of rare earth magnets in brushless dc motors and permanent magnet synchronous motors increases the cost of construction. The synchronous reluctance motor is a suitable replacement for existing electric motors because of the absence of high-cost rare earth magnets and simple construction with easy maintenance. This paper proposes the dynamic behavior of synchronous reluctance motors using the d-q model for electric propulsion. The direct and quadrature axis inductance values are obtained from the 2D model of synchronous reluctance motor and it is introduced in the d-q model as look-up tables. The motor design parameters are influenced by several electric vehicle characteristics such as weight, size, speed, and gradient. The performance of the developed synchronous reluctance motor is analyzed by variation in output parameters such as torque and speed concerning the input parameters. The aforementioned model is validated in different simulation platforms such as MATLAB and ANSYS platforms.
电动汽车中使用的电机,如感应电机,其动力特性不如感应电机。同样,在无刷直流电动机和永磁同步电机中使用稀土磁体增加了建造成本。同步磁阻电机不需要高成本的稀土磁体,结构简单,易于维护,是现有电动机的合适替代品。本文用d-q模型研究了同步磁阻电动机的动力特性。从同步磁阻电机的二维模型中得到直轴和交轴电感值,并以查找表的形式引入到d-q模型中。电机设计参数受电动汽车的重量、尺寸、速度和坡度等特性的影响。通过分析同步磁阻电机的转矩、转速等输出参数与输入参数的关系,分析了同步磁阻电机的性能。在MATLAB和ANSYS等不同的仿真平台上对上述模型进行了验证。
